Guys with Gmmg and H/C come in!
Has anyone with a Gmmg and a cam installed anything in the I pipe to try and quiet it down some?
I'm thinking of having Gmmg make me a third muffler to put in the I pipe possibly held in by clamps where I can switch the two pieces out.
What do you guys think? How long should the muffler be and do you think it will quiet it down much? I figured this will help a little bit in the rasp department as well.
