🏍️ Enhanced Performance & Noise Reduction: MASO Universal 60mm Motorcycle Exhaust Muffler Pipe with DB Killer Silencer Review

Huge difference after installation, now I like the noise level. I had to use my own bolts to attach it more tightly and I also had to cut a hole in my exhaust but it's very strong now.

This made my bike quieter, uses a dB meter and yes it's quieter. I'm not sure how that affects performance. my bike is a 2001 cbr f4i with a stock muffler that someone gutted.

There is only one bolt hole and the fit is a little loose, causing the muffler to vibrate in place. The welds suddenly burst and the muffler fell into the exhaust pipe.

The largest Maso size was 60mm, which was about 1/4 inch smaller than the existing holes. The baffle mates with the existing muffler inner liner and wire mesh. I was lucky, it was exactly 60 mm. Some…
