i use lt and have no trouble pulling the tranny out for a clutch, its really bad wen you have a auto, but i didn't see it as a big issue

 

If you have the flowmasters you will most likely want the H pipe. I have the H with flowmasters and it sounds bad ass... Suposedly the X with a chamberd muffler sounds like ass

 

I think I'll go with the H pipe and maybe a different series of flowmaster's, to get a better sound. I'll stick with the 3.55's for now though.

 

long tube headers aren't that hard to install. You can do it without moving your motor, but if you have big hands you might bust your knuckles a bit. but definately long tubes.
and don't waste your money on getting an h pipe if you already have and x

 

if you think long tubes in a Mustang suck try putting Mustang mid-legnth 302 headers in a 351 Crown Vic ( i did it when everyone said you can only use shorties.)

 

I'm running flowtech redhots into turndowns with an h pipe and shorties... call me crazy, but I love the way it sounds compared to the droning 40 series flows, I've got a lot of compliments on it.

 

i agree with vince, i hate the drone from my single chamber flows,

 

I enjoy my 3.73's, gets good torque in pretty much whatever gear. Makes it more fun to drive imo..
