i have a magnaflow muffler...2 1/2 inch mandrel bend custom catback...soon to make it dual exhaust just for the looks even tho it wont do anythign with the power...

i dont have any dynos but i've driven it hard when i was running stock and i drive it hard now with my mods...and you can definately feel a stronger pull, but not by much...even with any mods that only helps you gain 10 hp on such a heavy vehicle...like i said b4 on a previous thread...if you really wanan go fast, do an engine swap..or get the supercharger/exhaust/intake, and gut the whole interior and replace the two front seats with sparcos or bride racing seats and im pretty sure it'll shed many hundreds of pounds which will DEFINATELY improve your performance.
