Hey I am curious what you guys think I should run for an exhaust. I have a 1982 Camaro and the engine is getting the finishing touches at the shop. Here is how it wound up:

377ci Small block
11.7:1 compression
Pro Topline 235cc Aluminum Heads, 2.08/1.6 Valves, CNC chambers
Billet Roller Camshaft, 262/266@.050, .665/.625 lift
Jesel SS Shaft Rockers, 1.6/1.6 ratio
Bowtie Single Plane Intake, 1050 Dominator
Hooker Super Comp 1 7/8" Headers w/ 3.5" collectors

This is a drag radial street/strip car (mostly strip obviously) but I do still drive it on the street. Any recomendations for an exhaust system?

 

1.75" dia primary long tube headers....

doubt you'd see a gain going to bigger primaries.

behind that....true duals dumped.

 

I already have the headers, I am looking for what to put after the headers. I was more looking for suggestions on pipe diameter and mufflers.

 

if you have the clearance...3" and some magnaflow 4x9 straight thrus

works great on my 400rwhp LS1

you could probably run 2.5" pipes without a noticable power lose...but if you have the room or just want the best possible flow...3"

as for the mufflers. they are straight through glasspack design, which will flow great, but keep noise to a reasonable level. do a search for my videos, a side by side comparison of my car with straight pipes and then with the MF mufflers...you almost can't hear the car run.
