help with mods on mod motors

[Duane'97gt2v]

I've got 2.5 in. h-pipe(no cats), 2 chamber Flows and I get alot of compliments on how good it sounds. I like the sound but it is almost too loud. some other mustang 4.6 owners in town have the same exhaust and theres aren't as loud as mine but still sound great. some buds of mine claim dynomax sounds best, but I would disagree. Never heard bassani, but I have heard borla, liked it alot. Add BBk underdrives, Upper intake plenum by trick flow, MAC cold air, throttle body, noticeable gains. Comp cams make a nice new range of cams that would work well with those PI heads you have, but they ain't cheap. Before adding procharger, I might consider an intake that is not plastic, the plastic tends to crack and bust under s/c and nitrous applications. Intakes aren't cheap either, the billit off the Bullit has tested good, I think procharger might even make one that would do better. 3.55 to 3.73 gears work great with the 5spd. Ford racing alluminum drive shaft would be nice too.
