20ish hp. other mods will effect the performance of the exhaust. the more you need a good exhaust, the more it will help

I agree 17-24 rwhp for a full exhaust, is all that mandrel bent or are you piecing it together...

Why is there all the hating on flowmasters. They give fox body a pure muscle car sound without sacrificing much power at all. I just did full exhaust on my bone stock car and I didn't really feel that much of a difference. I doubt I got I got more then 10hp. You need to pull more air in really before exhaust will help out that much.

I can definately feel my exhast make a difference.
