Exhaust Noise Levels
I keep seeing questions regarding aftermarket exhaust slip-ons and complete system noise levels. I'm going to keep offering or asking anyone in the Syracuse area that has an aftermarket exhaust to stop by and we can get sound level data to compare.
I have the levels for the stock exhaust, then with the HMF slip-on and then with the HMF with the quiet core insert.
These were all taken using a standard test -so we can then compare apples to apples and have an idea of the different sound levels.
I love the HMF tone and peformance improvements!

I live in Buffalo and I have the Big Gun EvoR complete system and i love the way it sounds. It is loud though.
I used to hear the tires hum on the highway. Now I just hear the exhaust.
My friend has a stock KTM 400exc and when riding you cant hear his bike when I am around.

What levels did you get? How far away from the tailpipe were you? At what rpm?

Could you post what your "standard" test is so that we know what your reference data/point is? I have a sound meter and am interested in comparing my Thai Spec bikes stock exhaust to the 2BR M7 after I finish my break-in.

Big difference. The M7 should be up over 100db. It's one of the louder pipes on the market.

I also have the P4 tip in case the local law decide I am too loud which is easily resolved with some Johnny W.... There are a lot of 2 smokes running around so should not be an issue anyway.
