Monthly Testimony Log
The following information was taken first hand from the individuals experience with the XB08 exhaust system. Some are locals and some are from ebay or other online sources that emailed me information
concerning their experience with the product. Please email me at extremeblaster@gsxrexhaust.com if you would like your testimony posted.
Mitchel from California tested the first XB08 GSXR 600 06-07 pipe
Chris from Las Vegas tested the second XB08 600 06-07
Ron from Las Vegas GSXR 600 06-07
Moan from Las Vegas 08 Yamaha R6-S
I'm running ten plates now and the shifts are smooth (no pops when I get on and off the throttle). Good low end torque. Clutch up wheelies are smoother and more responsive. The mid pipe is still the
same raw aluminized color. The plates and end cap are gold now but from what I read in your notes I believe that is supposed to be ok. My buddy and I topped off our gas tanks yesterday (both 07 GSXR
600's) and went for a ride and his gas light actually came on about 3 miles before mine. If I run more plates I have better top end but the exhaust does not sound like it is flowing smooth while I am
cruising on the freeway at 85-90. I think it runs great with the ten plates in 60 to 100 degree weather.
Torque and midrange power gains are immediately noticeable over stock. Can't believe how heavy the cat was, we removed a lot of weight.
The 600 Gixxer was his wife's bike and I have since heard he enjoys riding it more then his Yamaha R6 cause it is more comfortable and handles better and now has more power.
Torque is unbelievable. Very happy with power gains.
.Increased power gains throughout powerband. Loves the look and the sound.
Moan saw what we did to Ron's bike and wanted the same thing on his R6. After I told him I only do Gixxer's he twisted my arm and I came up with a nice set up that has really good tone. Another guy
bought one from me on ebay installed it on his Yamaha 2000 R1 1000 and was very happy with it.

JD from Las Vegas 01-04 GSXR 1000
Performance is awesome and I really like how it looks and sounds. I reduced the plate count from 12 to 10 for added torque for easier wheelies.
I test rode his bike with the 10 plates and the torque is more then my 06 Gixxer 1000 and he has 22,000 miles on it. Easily spins the tire in second gear.

G2face ebay contact 01-04 GSXR 1000
what's up I love the pipe I got from you not too loud at idle and when you get on it that's when it sounds off. It even gave my bike more power. It was a good investment I'm glad I got it thanks.

Zayd from Brisbane Australia 08-09 GSXR 600-750
Not knowing what to expect from a fairly new product, but having done some research on the Supertrapps I figured why not? Kevin was of great help, personally responding to all my questions. The exhaust
arrived in the mail and my first thoughts getting it out of the box where 'wow that looks awesome'. less then 8 minutes later I had it on the bike, the first ever 08 Gixxer 750 to be fitted with that pipe and I was
amazed. It sounded great to begin with, had an exclusive look to it and when I took it out on a run I had the biggest grin on my face. Extremely happy to have tried and tested the XB08 Extremeblaster GSXR
exhaust which has brought about a whole new meaning to customizing your bike and being different. The sound, the design and especially the look from confused but amazed riders never seems to get
boring. 'How does this pipe work', they ask.... and I'm all too happy to explain starting off with 'you can tune the exhaust & bike with these plates', and the amazement continues".
Thanks Zayd

Rodney ebay contact 98-01 Yamaha R1 1000
Dude that pipe rocks, it really woke my R1 up. I had a carbon fiber pipe from exhaust specialties and I kinda felt like the bike wasnt running at it's full potential but that pipe makes my bike breath through
RPM's like it's hungry.

Pipe looks and sounds awesome. Very easy to install

Brandon local contact 08-09 Kawasaki ZX10R Slip on to header
Gave my bike a lot more torque and added horsepower. The Dyno showed I gained 8 horses to 165 hp rear wheel.

JC online contact 08-09 Kawasaki ZX10R Slip on to Cat
I like the tone and that it provides more back pressure for added torque since most of my riding is on the street in the lower RPM range. I can do wheelies in second gear much easier, can't complain about
anything. I finally got rid of the 500 lb ugly stock exhaust and my bike got the look I was looking for! The installation was a 10 minute job and I didn't get a FI light. Like the idea I don't need a Power
Commander to make my pipe work. I'm really happy with your product!!!

Anthony  online contact Suzuki 01-04 GSXR 1000
You won't believe the sound and even better the looks when other bikers see this thing. They can't believe it gives off the sound that it does and that it's totally enclosed which is baffling to them (no pun
intended). This was the best and most inexpensive decision I have made (that includes the fee from the dealership to install and remap my Power Commander)                                                                          
      
A lot of success and added power can be obtained by utilizing a Power Commander you just have to know what you are doing when remapping the fuel controller.

Desertbum  Ebay contact Yamaha 06-09 R6S
The bike starts right up and runs remarkably better then when I had 2 bros exhaust on my bike. I get better response when opening up the throttle and the plates so far are a golden color. So far I am very
pleased with product. Tyler

Thanks so much for your response. It sure looks great on my bike and sounds really awesome after installation, thank God I got rid of that stock ugly big pipe.

I decided on 9) disks and I love it., sounds great but I wish I new you did black powder coat cause that would have gone really good with my bike

Carlo  online contact Yamaha 03-05 R6
I am still running 10) plates. I am happy with the performance and sound. I had my buddy take it for a spin and it sounded great from afar.

Dr Loverous  online contact Suzuki 03 GSXR 1000
This pipe is awesome! The sound is great. Not too loud but enough that I am heard coming and going. The idle sound is wonderful. My mechanic loved it too and noticed the increase in power and said my
2003 GSXR 1000 now sounds like a real bike, a moto GP bike. That's awesome! I love it's sound in 1st gear just cruising at 4-7000 rpm, and my gas mileage has improved. I usually get 130 miles to a tank
when my low fuel light comes on and i'm at 146 miles with no fuel light yet. I haven't heard it maxxed out at high speeds yet but excited to get there. I think because people hear me now it's attracting crowds
which makes me ride slower. That's a good thing though. Man thank you for this. I wish I had found this sooner.
I love this guy! Dr Love gets the Mr. Enthusiastic award. So much so I added him for Sept.

Usually between 140-150 mph the bike starts to shake hard so I back down for my comfort. But tonight if I could have would have shot for 160-170!!!! DAMN THAT WAS SO AWESOME!!!!  That little pipe
made such a huge difference in high end speed that the bike was begging for more and I wanted every bit of it! I am sooo glad I git this pipe now.
 Amazing Grace with the right equipment.

Ricardo  online contact 2007 Yamaha R6S
All I can say is "WOW" My hands are still shakin from the rush I just got. Got my XB in the mail today and couldn't wait to open the box (which I think was glowing). From the time I put my bike on it's stand, it
was 10 minutes, and I was firing it up for a ride. I pulled out of the driveway and turned the corner like I always do, but this time the front end came up like it was nothing. I was like a kid with a new toy.
Totally amazed with the sound, performance, look, price, and ease of installation. You guys ROCK!!!  
There must be a revival going on someplace. Enough Said? I think not, see November

Ricardo  online contact 2007 Yamaha R6S
We had a local bike night at a speed shop close to my house last weekend and I was so excited about taking my bike and letting my friends hear this awesome exhaust. Well, they talked me into putting
my bike up against a bunch of other 600s on the Dyno. Wasn't expecting much cuz my bike is stock other then the XB I put on. Well, I won. I got 117 hp @ 12843 RPM. The performance and looks of your
exhaust really impressed everybody, can't thank you enough..
Thanksgiving is upon us! Thank You Ricardo for sharing. 117 hp very impressive on a R6S, and without a PC! Amen and pass the race gas

Darren  online contact 2002-2003 Yamaha YZF R1
Pipe is awesome!!! To say that I am stunned at the amount of low end power I got from it would be an understatement. Best street exhaust I have ever got. I ride on the street or through the canyons by my
house. Rarely do I get a chance to really top it out, so this pipe really gives me power I can really use. The sound is to die for. Not extremely loud when I am cruising through the neighborhood at 5am going
to work, but when I get on it, lets just say I can't get enough. As far as the look? Everyone loves it. Short, modern and black to match the rest of my blacked out R1. I couldn't be happier This exhaust ROCKS!!!

Kevin  online contact 2001-2003 Suzuki GSXR 600-750
The pipe is amazing! I can tell the difference from the other aftermarket pipe I had as far as torque, horsepower and it sounds great... Being able to add and remove plates for high end horsepower and low
end torque is nice. Very impressed with the extremeblaster!

Zach  online contact 1996-2005 1200 Suzuki Bandit
Got the pipe on today. Perfect fit! I am very pleased. The Bandit was stock at 96 hp, after I put your exhaust on it ran 106 hp. With stage 3 jet kit, K&N filter and wheelie wire disconnected it ran 126hp! I want
to thank you for all your time and effort in making my exhaust.  
This was the first Bandit 1200 exhaust I made for him. Zach was very helpful in the process. Thanks Zach!

Kaz  Local Las Vegas contact 2005-2006 GSXR Suzuki 1000
Exhaust sounds great! Took it out for a true test with my GPS installed and quickly topped out the 189 mph speedo but got a true 189 mph on the GPS on my first ride and the bike was still climbing before I
shut it down in a strong head wind. This performance easily exceeded my former aftermarket exhaust and will attempt 200 mph run after I get my Power Commander tuned on the Dyno.  Kaz
is a local here
and I helped him install the pipe. He is a professional motorcycle drag racer and I can attest to his performance claims. I'll check back with him if I can catch him!

Adam  online contact 06-09 Yamaha R6S
I got a lot of questions about the pipe. No one in Sacramento has seen it. Everyone scratches their head at it, but when they hear the sound they have BIG smiles and ask where they can get it. I'll let them
all know where to get it for. I reduced the plates to nine but put it back to ten the way I received it because I really like the way it screams with ten plates.
July 2011
Andrew  online contact 1998-2002 Yamaha R6
It was a quick thing to put on (15 minutes) It also sounds like a beast! This exhaust is so awesome. The sound was a little to throaty and deep for me with the ten plates I received it with so after testing
several plate variations all the way down to 3 plates and  I am running 5 now for the best tone the way I like it and I think it is awesome.  The length is perfect and it comes close to the swing arm without
touching even after bouncing the bike. What is the exact name of this pipe? (besides mine)
Just call it the pipe with no name or Brand X! I call it the XB Extremeblaster. Thanks for your feedback Andrew.
That's what I like about this pipe in two words, versatile and flexible. You like top end? you got it, low end? it's there, you want tone? it's all yours. Adam tuned this thing to his ear, Love it!

Todd  online contact 2002-2003 Yamaha YZF R1
First let me say that I am very happy with the service before and after the sell, I was mostly sold on the look the XB would give my bike. After 4 or so emails I can see they are very invested in their product.
First, I ran the pipe with 10 plates and found I wanted more low end response. It was suggested I remove 1 plate at a time with about 50 miles of run time till I changed. I didn't listen my mistake. I dropped
to 8 plates right off. It was a significant increase in low end response with very little change at the top, and the pipe was a lot more quite. I put 250 miles on 8 plates and went back to 9 plates. I have a sound
that is a little lower tone then a Yoshi pipe. I have all the torque I need to get me out of a corner and the pipe looks great. No need to use a Power Commander if all I have to do is remove a plate. The guys at
XB know what's up.
Thanks Todd for the awesome review. This is a testimony to the R1's flexibility with the reduction of 2 plates massive throttle response without top end loss and significant db loss.
