Jardine GP-1 Stainless Steel Slip-On Exhaust

Great Product. 5 stars for Ease of Installation, Style, and Durability. However, 4 stars for performance because it takes away from your back pressure which makes for a rougher start of your bike without a fuel mapper. This part gets a 4 for power as it does not increase the power of the bike. This part does make the bike sound much better with the stock headers/cat but its overly obnoxious with after market headers like an 05 header mod, MJS headers, or mid pipe. I do recommend this exhaust, just giving you all the info. on it. Hope this helped!

Bought this for my 09 Gixxer 600 to get rid of the huge, heavy stock canister. To me, sounds on par with or even better than some other "real" slip ons. Very deep, throaty and gives it a nice "pop" when de-accelerating. Can't really comment on power gains, since I installed a PC-V at the same time. Definitely a noticable low end gain with that combo though. I've had a few strangers walk up to my bike in public just to find out what exhaust I had and comment on how good it sounds and clean it looks.

More power and fastest. Great product.

Ladies and gentlemen, if you subscribe to the phrase "LOUD BIKES SAVES LIVES" then rest assured, you are going to live out your days on your Hayabusa without incident.. I actually added the sound reducers which I had the drill into the pipes as they are just way too loud for me? The pipes still are incredibly loud! I have not heard a pipe that sounds this good on any bike. The youtube videos do not even remotely represent the deafening roar on these pipes which is even louder than without any slip-ons installed. As for power added, I doubt there is anyone who has ridden a stock 2011 Hayabusa that thinks it needs more power. Haha! Even if they added 5% of the total power i don't think i could notice the difference of nearly 10 hp with nearly 200 stock hp. Anyway, very satisfied with these pipes. Please note the left side was a little difficult to install but just place the pipe on at the base and keep applying upward pressure to the tip until the bolt pops thru the hole in the bracket.

this pipe was super easy to install, super cheap and twice as loud as any other exhaust ive ever heard. Just make sure you ask someone what to do with the exup wires if you're on a yamaha or you're going to lose low end power. Its a perfect tone too, not too high, not too low.

Awesome pipes !! Looks good, sounds great !! I love them !! For the price you cant beat the deal you get on these awesome pipes !!! I recommend them to anyone wanting a clean look and Fantastic sound !!!
