Default GMMG cam only through manifolds, debating headers...

Would the quality of the sound /loudness be obnoxious if I was to add headers through a catted y pipe with GMMG?

Right now I like the way how it sounds with the cam through manifolds.

Keep in mind that this is my daily driver, and I've heard GMMG through straight headers/pipes and it was just way too loud.

Wondering if with the cats it would be bareable???

Thoughts?

I think it will sound great with headers and a catted y; and you should enjoy the bump in hp too with that cam.

If it is too loud, a small magnaflow bullet can be thrown in the intermediate pipe to help quiet things down a bit.

Don't know what LS1powrd was saying. But I don't think its that bad. I have a MS3 with trick flow 220s ARH1 7/8 ORY into a GMMG. Yes drone is bad but I am putting dynomat all over in my car. There are many other ways to tame the sound down but I like it loud. If concerned get the catted Y. High flow cats don't take away that much HP anyway.

I agree it shouldnt be terrible with the catted Y. With no cats it would probably be pretty bad.

High flow cats are excellent, great sound/kills drone.

def. buy some HF cats if you get headers. if that is still too loud for you buy a powerstick (basically same chambered muffler as gmmg) and weld it in the I-pipe
