Ditch Your Stock Pipe

Zach in WA – Machine this part was bought for: 2013 SUZUKI RMZ250

Comments On Nov 17, 2014:I needed to get a spark arrestor and had narrowed down my choice to either the 4.1 or the q4. I was concerned about how loud the 4.1 would be for trail riding and although it is deeper with the quiet insert installed it is not raspy or headache causing. Put your "Rich" EFI plug in and get out and ride.

instant performance upgrade

jeromy in NE – Machine this part was bought for: 2014 KTM 450 XC-W

Comments On Jul 21, 2014:Besides the coolest exhaust note yet: this along with the FMF Grunt added imediate & noticable improvement in the throttle response & low end for my bike over the stock silencer. I hope I don't have to but I'd purchace it again.

Additional Comments On Jul 21, 2014:I typed FMF grunt when meaning FMF Snap.

Major torque increase in 450SXF

Brad in Arizona – Machine this part was bought for: 2013 KTM 450 SX-F

Comments On Dec 04, 2013:This pipe absolutely cures the common complaint about the new 450SXF's lacking on bottom end torque. 3rd gear wheelies out of hairpin corners are common now even without a clutch kick. Once you take your stock muffler off, try looking through it and you'll see why the bike is so choked up.
