Hey, just wanted some thoughts on where to go from here
I have an 03 mach 1 with following parts:
Jba cat back
Steeda cold air
Steeda underdrive pullies
Mgw short throw shifter

I'm a bit afraid of changing rear end gears since this pony sees a fair amount of highway and don't wana b real high rpm driving around, thought maybe high flow cats then dyno tune? Dunno about the cats since I wana stay with h pipe and I think headders have to be done at the same time, but it looks like id have to pull the engine to get enough room to get em in. Maybe some suspension or a light weight drive shaft?
Thanks for any thoughts guys!

i have 3.73's and its not much worse the stock...probably 200 to 300 higher....i would do those and programer. and you don't have to pull the engine to install the headers...they are just a pita to do

for the mach 1 410's are perfect:gringreen the engine responds good to the added 600 or so more rpm's.

think i might do 3.73s so i dont kill my top end speed,
thanks guys
