im getting the exhaust redone on my 89 iroc and have alot of aftermarket parts that im afraid will interfere with the exhaust setup that i was planning on doing. let me know what size exhaust u think i can run with my setup as it is now.

i have a t-56 installed as well as a spohn torque arm, hooker LT'sand a currie 9" rear. i initially wanted to do a 2.75" dual setup, but i doubt that thats feasible now. what is the largest exhaust i could possibly run with this setup?

thanks

All the 3 inch catback exhaust should work well as long as u get the right one for ure application.

Dual 2.75" is overkill for most str applications, unless you're puttin out serious hp.

Dual 2.25" is equivalent to 3" single.

I'd just go single 3".

Depends on your engine, how much hp is it putting out?

Isn't the torque arm and the exhaust on seperate sides of the driveshaft? I think any 3" would be good.
