Default Back pressure...

I have my new exhaust setup and have been hearing tales baout backpressure form some local guys. I have my longtubes with ory and Lm. Would I be better off with a resonator or a muffler for performance?

I ran LT's, ORY and a hooker CB, on my completely stock motor with no problems.

You NEVER want backpressure. Period. This has been discussed in great detail many times.

Here: https://ls1tech.com/forums/generation-iii-external-engine/324016-mufflex-4-gmmg-corsa-true-duals.html

This is a current thread that gets onto the backpressure/exhaust gas velocity topic by page three (if not earlier).
