ISTUNT Universal 51mm Slip-on Modified Motorcycle Exhaust Pipe Muffler: Enhance Performance and Sound Review

Bought to race my 2000 Kawasaki ZX6r. Excellent quality and value for money! Loud, smooth sound and strong. I love it! I had to come up with another way to connect the hooks for my bike but very thick and nice! Fast shipping and delivery.

Good price, good sound. Replaced my fake Toce exhaust with this one and I like it a lot more, the Toce screamed too loud for my liking but it has a nice low rumble and is much easier on the ears when riding for long periods.

I bought a 51mm for a 2017 Yamaha YZF r3 but it does not fit. The hole is too big for the exhaust. I think you need to weld an extra piece of metal (extension) otherwise the exhaust will touch the rear frame and possibly scratch it. I have contacted the owner but no response. Is there an extension we can buy to solve my problem?

SO LOUD has been damaged. Your neighbors will hate you. basically a straight pipe, similar to a silencer. I didn't order a baffle when I ordered mine, do yourself a favor and add one, this is ridiculous. looks good, the sound was exactly what I wanted personally. I ordered a baffle and now it's amazing. One star deduction because the box should actually contain a baffle plate for the main counter pressure.

Well made exhaust. The springs are too long but you can order new ones or go to the extreme point of the hook and they work fine. On FZ-07 I had to make a bracket so it wouldn't rub on the pendulum and brake lever. It is very loud. In practice, the bike has a straight tube. If you don't need that kind of sound, I recommend buying a deflector. I love it. The machines can definitely hear me.

Works and looks like it should. Save yourself a lot of hassle and buy the included adapter which works but doesn't reach to the exhaust hanger and welding is required unless your bike already has spring hooks on the down tube. Very loud so if you want to muffle it a bit add a muffler because that idiot turned my 400 into a Harley. I bought the matching adapter from Kajimotor on Revain, also a great product and it took me 5 minutes to install everything.

This is a really nice looking muffler that has a tough feel and is made out of real steel that can withstand high temperatures. I would recommend it to anyone looking for a quality exhaust at a great price. My reason for 4 stars is how loud and solid it is. I live in an apartment and work late, so I knew when I bought it that it would be loud, but not as loud as it was. It was too loud for my comfort and didn't have the growling sound I wanted. If you're buying this for a Ninja 300 like me, be…
