I'm just curious if and how much torque is affected by eliminating the catalytic converter by using a straight thru pipe? What about at low and high rpms?

Here are my major mods related to airflow:

91 Z28 305TPI: Gutted airbox, edel intake, ported plenum, edel runners, edel headers, 3" cat, 3" flowmaster catback...and basically every mod out there except for the heads and cam...which will come when i get a 350.

Thanks in advance for any replies.

Bugsy

 

anyone?

 

You will have more torque and hp because you have less backpressure period.
