Default GMMG or go dual

I'm about to do a heads and cam swap on my car. Ported 243's and a torquer V3 along with a few other things. I can't decide on going true duals or just keep the ORY and GMMG I already have. I've researched it and just can't decide on what to do. So let me hear some opinions on which set up

Very true words.

GMMG doesn't even compare to a decent set of duals. Y pipes make the car sound like a boat...some systems more than others, but it's always there.

why do people make posts on questions they already know the answer to???????

Of course its gonna be True Duals, the GMMG in essence is still a catback. No catback will ever compete with a nice true dual set up.

I have a GMMG it sounds awesome on a stockish car, the minute you put headers on your car it will be insanely loud and obnoxious. If you have the cash and the know how, go with a solid true dual set up without cutting corners.

I already have headers and my car sounds fine with the GMMG. If I knew the answer to my question I would not have asked it. Maybe someday I will have all the answers like I suppose you do.

having the ORY with a head/cam setup is going to ruin the sound of the GMMG. either slap on some cats, or go TD.

Go with 3 inch duals with a badass x-pipe. And either bullets or single chambers.

Hard to beat the beautiful sound with no rasp.

If you have no Cats GMMG will sound raspy and Loud as *** with LT. if you have hi-flo cats it sounds nasty for a catback.

Hey TORCHED, with our builds i think we are equally loud. You also have a powerstick bullet muffler in place and im sure that kills the rasp and obnoxious loudness. I love my setup.
