Best Performance decision!

I put this on my 2018 DRZ 125 and it literally probably goes 10mph faster! Very easy to put on your self, took me about 15 mins in total to remove my old stock pipe and to put on my new FMF pipe. I ABSOLUTELY LOVE THIS PIPE!!!

Bought for 2016 drz400sm

I bought this exhaust as just a slip on taking off the stock exhaust was no issue but when putting the fmf on the tab that is behind the passenger pegs was a bit of a pain in the butt to put in once it was installed the gasket to the muffler support kept falling off and was annoying in my opinion also was kind of loose around the muffler. Overall it gave my bike a great sound and much louder than the stock one #loudpipesavelives

Power Core 4

I have not yet had a chance to ride my bike for a test But I will say it sounds amazing. It is as good as I hoped for and even better. If you have a four stroke bike it's the best you can do to get some noise going. No longer sounds like a trail bike. I'll also say it's a better sound in person than you may see on youtube. well worth the cost.

Raptor 660

Best exhaust ever super mean sound really, really loud I have it on my 2002 Yamaha Raptor 660 it´s the fastest quad I have ever owned, a couple of harleys road by my house the other day and I was on my raptor they started revving and I did it back and mine was definitely louder I will always buy a powercore 4 for my quads or dirtbikes if it fits. I get the police called on me all the time with this pipe riding in my front yard cops come 2 or 3 times every time I get on it a neighbor moved because they said it was to loud and the cops were not doing anything about it :) :)

Better Than Expected!

Amazing! This pipe was super easy to install and it sounds great! It gave my 1998 DR 650 a make over, I was amazed by the power difference. Definitely worth the price, I am impressed!
