Description

Description for S&S Cycle 4.5" GNX Black Slip-On Mufflers

The M8 engine has various pros versus the prior Twin Cam engine, however there are a few cons that have surfaced such as the low idle note combined with a choked stock exhaust system that doesn't allow the sound most are used to. S&S Cycle has heard the customers and created the GNX slip-on mufflers. This pair of mufflers combine a 4.5" muffler body equipped with a tuned baffle and finished off with their race inspired end cap, letting the sound and power flow as it should.

Look good, sound good. Muffler clamps are cheap garbage.

Quality parts, has everything you need to switch mufflers. Nice exhaust clamps, good fit and finish. Quiet a cruising speed. They burn in nicely to a deep throaty tune when you’re on the gas. Lots of bang for the buck.

Fit and finish is pretty close. Sound is really nice with DB killers removed. Very good looking set of slip-on for the money.

The sound is better than I expected and more quiet than similar products I have used. I highly recommend these mufflers for sound, appearance and quality construction.

Love these pipes, was referred by a friend. Fit is perfect, they look great and the 4.5's really look solid! Sound great when just cruising but when you crack it, it talks back!

Great Buy
Love these pipes, they were referred to me by a friend. They sound great at cruising speeds while still able to hear the radio but when you crack it, it talks back. Great delivery time from J&P too. Cant beat the price, Would buy again.

Easy hassle free install. I was hoping for a little louder exhaust note. They do make the the bike sound better
