im trying to start a poll on what people think the best exhaust is for a 1989 Camaro z28 with the 5.7 350 in it were going to continue building this motor with patriot heads, a new hydro roller camshaft a new intake manifold with a Holley 700cfm carb I’m trying to hit 500 horse out of this motor and want the best exhaust and headers that can take performance let me know your thoughts and suggestions!!

 

You will need long tube headers with 1_3/4 primaries and at least a 4" exhaust but all that is easy. Building a true 500 hp motor will be the challenge you will need at least 210cc heads and a 6500 peak HP to crack that 500hp mark. Also pay attention to everything all the little details like deck height and perfect valve train geometry will come into play

 

what’s the best headers to actually get? Hooker competitions? And if I got 210cc heads most likely I would need AFR Performance heads I’m sure? I know a lot will have to do with the camshaft I choose that’s the hard part
