I ordered calspeeds 1 7/8" headers i have a buddy that has them an theyve
Proven to be of good quality an make good power n/a
I just wanted to know if 3" exhaust gutted cats will work fine on n/a
L76 only mods are tune headers an drop in filter
I dont want to lose backpressure thanks!!!

 

why do you want gutted cats?
is it 3" single exhaust or dual?

 

Please explain this "backpressure" you desire.

 

^^beat me to it.

usually people buy headers and free flowing exhaust to help it breath better not keep it restricted

 

Ok, heres my opinion just did a setup on a buddys truck sounds great, after the headers I would do a 3'' X-pipe, 3'' duals into some magnaflows thats just me
