    Hey guys :-)

    My 04 gtp currently has pace setter ceramic coated headers, zzp 3in no cat downpipe, flowmasters idk what series, but I'm looking to change it up.

    I want a deep badass sounding tone, to me the flowmasters somewhat sound like a lawnmower lol, i love loud but what mufflers or what can I change to get a deep tone?

    good luck finding a deep exhaust note coming out of the 3800 engine . I thought by putting a 44 series I would achieve that well I was wrong and only had the mufflers installed for 1 day.

    Yup. Pull 3800, remove floor, install f-body floorpan with necessary body mods, along with LSx and T-56/4L60E, get exhaust, enjoy.

    You cant really make a transverse 3800 sound good.

    Put some borla's on there, thats about the best you are gunna get.

    Ehh.. the "best" sounding 3.8's the engine is drowned out by a turbo or blower. The engine sounds bad at anything other then idle.

    Flowmaster's suck.

    Pacesetter's have their own downpipe, so not sure how you have a 3" ZZP one...do you have true dual exhaust?

    Catted WBS Store Headers, with a full dynomax catback sounded good on an '04 GTP...quiet is the key, unless you have some dumb small pulley, monster bird catching hair dryer, or some mega pointless huge lift cam.

    The biggest magnaflow resonator you can buy with two manaflow's out back. Also put a cat on it. It'll be more mellow and less raspy

    I love the sound of my car. And i get alot of compliments on it at car shows and track days. No it will never be a sexy, deep, rumbling v8. But its not a pissed off 4 banger either.
