curious on upgrades

bluegtp91, the worst 3800s I've heard are catless 3800s. There's so little flow difference from cat'd to catless, I'd put one on just for the better sound.

i backed into the concrete blocks on the side of my driveway, and dented the pass muffler and in doing that the whole exhaust actually got pushed forward like 3", its some what fixed but the ubend is fubared so i gotta replace the whole thing anyway. i like the stock sound at idle...i just dunno which mufflers to go with for the deeper sound.

do you have to get a new pcm if dropping to 3.6pulley? its prolly recommended anyway just for all the tuning tho isnt it? which pcm is the best for the 04s?

(Just trying to knock some cheap upgrades out of the way before takin it to the drag strip

)

Well between the catless vs. resonator-less 3800's I'd say a catless one sounds TONS better than a 3800 without a resonator. Plus I have headers. It makes the tone a bit deeper IMO.

But...to each his own. I love the way my car sounds.

i agree with that. dropping the cat really doesnt do much. gonna make ya not pass emissions and have raspy sound
