My Q2 came today from BikeBandit.com. They had the best price by at least $50-100 from anywhere else. I have seen a lot of post about this pipe but not so much of a review, I figured I would put together a comprehensive review of this pipe to help others decide if they would like to buy this or not. Maybe this can help you decide before you spend your hard earned money. This review is my opinion only from my experience. I am using what I have learned from the 22 years of riding and the pipes I have owned on various bikes in the past include: Hard Krome, FMF, Pro Circuit, HMF, Supertrapp, LRD, Bill’s, M4 and Micron. The fit and finish is very nice and the aluminum ‘can’ is much thicker than some of the FMF products I have purchased in the past. Seems more durable. It bolted right up just fine, perfect fit. It does touch my rear fender on the side of the can, just a couple of mm if it touches. This thing is MUCH louder than my stocker; I was expecting this to not be nearly as loud as it is. The stocker is around 80 or so decibels. I would suspect the Q2 to be about between 94db on my bike. For every six decibels, the intensity of the sound doubles. So the Q2 is roughly 2.5 times louder than stock. It is nowhere near as loud as my PC pipe on my RM but much louder than stock. The tone is deeper and makes the bike sound like it has some balls. The pipe is lighter but not substantially so the weight difference is not drastic. The bike has Dave’s mods and been rejetted, my UNI filter was back ordered and will show up Monday so it is running a stock filter. I took it for a spin and I can say that I did NOT notice any power gains. Maybe a dyno could confirm more but the butt dyno says no. Adding the air filter may make a difference. Things that the pictures do not show you about this pipe are. There are allen screws at the back of the can to remove for repacking, this is definitely a plus, versus drilling rivets. Also the end if the pipe does have an allen screw to remove the spark arrestor. The spark arrestor is a coned screen type. The anodized finish is done very well. Is this pipe for you? If you want a deeper throaty nice sounding pipe that looks a lot better than stock that is not obnoxiously loud yes! If you are expecting to save lots of weight, looking for a substantial HP increase, or looking for a stealth machine, no! No doubt if you have added a high compression piston, cams, ext. you would no doubt get much more out of this pipe versus stock. If I had to do it all over again would I buy it again, but I would have waited and used that money to do other mods and add this one later. Cheers! Ride safe Ride often!
