if the mach was yours.. what exhaust would you get ?

I am leaning towards a catted X or H pipe..i wanted to keep the similar sound it has now.. it'll be louder.. but i dont want the raspy sound..so i was leaning towards H-Pipe.. but i cant find a good quality one i like.. more to the point....i dont knwo anything about the makers.. what works.. what doesnt..

also.. X vs H .. i see in 5.0 they tested a black mach 1.. got it inot the 11;s with some mods.. they ran a full bassani exhaust.. headers.. x pipe (off road) and cat back.. any idea where i could get more info on that system ?.. preferably just the headers/x-pipe.. leave the catback stock for now..

also.. soon i am getting 4.30's.. and a shifter (thinking the MRT one).. plus either DR's OR 4 falkens all round (for AutoX).. but not sure how the falkens will hook on the street.. anyone ever autoxed on DR's ?..i could get falkens up front and DR's in the back until i can afford 2 more stock wheels for falkens all round on the autox course..

thanks
