fantastic slip-ons I am very impressed! Fit and finish is superb, sounds every bit as good as they look too. Installation was a bit of a challenge on my 2008 KTM 990 SuperDuke. If you are mechanically inclined at all, you will figure it out no sweat. These pipes are extremely loud. Deep, aggressive tone with a heck of a bark. At cruising speed they are very tame and not annoying at all. I would highly recommend these slip-ons to anyone that doesn't mind a bit of noise. RevZilla really impressed me with their fast service and outstanding customer support. This is the place to buy them without a doubt! June 25, 2014
The ONLY exhaust for an R1! I have this exhaust on my R1 and immediately it makes it look sexy and sound mean...you know, kind of like it already does except this perfects it! I get nothing but compliments about these pipes and have even had people trying to trade me their pipes for them! There is no other set like it out there and it seriously compliments the R1 like no other bike.Well worth the price and installation is a cinch! There is no possible way to regret this purchase Instantly adds wow factor and value. SOUND: Perfect. It's very deceptive on low RPM's but when the throttle is opened, this set SCREAMS! AESTHETICS: Razor sharp styling that compliments the R1's undertail PERFECTLY PRICE: You really get what you pay for here. It doesn't disappoint. INSTALLATION: Simple...really simple. LONGEVITY: I've only put 7k on them and no hiccups. CONS: You WILL need to remap your fuel because it does backfire on decel. But, for 90 bucks why aren't you just flashing your ECU already!@#???
