          Rated 5 out of 5 by from Great slip on, really light. okay price Bought this slip on to get some weight off my KTM, makes the bike breath better and sound better, the stock exhaust is really heavy and this thing is light as heck and makes the bike work better too. No need to do anything to the bike, just bolt it on and go! Again only bought it for the weight and look not for power.

          Rated 5 out of 5 by from Good upgrade This pipe companies to stock is night at day, it's about an inch shorter, but it's a bit wider and significantly lighter. It says the pipe doesn't come with a spark arrestor, it does, also comes with a wash plug and like 8 FMF stickers for added HP. I had a small issue mounting, the thread clip needed to have a tap ran through it, not a huge deal. Everything lined up extraordinarily well for aftermarket. Pipe sounds good, the bike fired right up.

          Is this pipe really loud im looking for an exhuast for my 16 crf450r to make it sound a lot better and louder is this the muffler for me?

          Asked by: Crf450r
          Not sure on your 450 but I put it on my 350 and it has a great bark but not obnoxious. Notices the power gains too over the stock muffler
