help with mods on mod motors

[fordblue5oh]

Well guys i finally crossed over into mod motor territory. I just picked up a sweet 02 sonic blue 5sp gt(only 10,000 miles!). I've been into mustangs for years but it has been exclusively fox bodies with 5oh's so now its like im starting over i plan on installing a p1sc procharger after i recover from the down payment but in the mean time what are some good bolt on's? I am also worried about exaust i already priced full 3" at a local speed shop and have always loved 40 series 2chamber flowmasters but i have a friend who has a 01 with off road h pipe and 2 chambers all 2 1/2" and as much as i hate to say it sounds like crap. It sounds good getting on it but when you let off it sounds like the whole exaust is loose and is going to fall off the car(this is not the case we already checked). Anyway beeing a mustang guy the exaust sound is very important to me. Can you guys suggest any combos that you have or have heard? Any suggestions would be appreciated. thanks!
