Subject: RE:Help with 91 L98 Performance Mod's by bogus on 2005/9/30 14:02:06 I agree. Exhaust on these engines is the #1 restriction. Long Tube Headers High-Flow cats x-pipe Cat back exhaust of your choice. I like Corsa, simply because it is less boomy. That setup would be worth upwards of 50hp. Yes, the stock exhaust is THAT restrictive. I personally hate the TPI setup. It won't breath past 5000 RPM worth crap. I would ditch it and go with a SuperRam or MiniRam setup. Add a cam, roller rockers (1.6:1) and life should be good. With all those mods, I see 300RWHP in your future. If you want more, then you have to mess with heads and dig deeper into the motor. |
