    Hi guys, I posted a thread about the PP muffs looking for a quieter muffler then there quiet muffler. I can't take the noise anymore. I put them on two months ago and I'm hoping I can find something quieter. I have tinnitus (constant ringing of the ears) and I need to do something besides wearing ear plugs. Any ideas?

    No , the ECM has no way of knowing exhaust restriction on those engines. Get those muffs off and put some free flowing ones on.
