Who says the LS1's aren't best mod for mod? 65rwhp with just an exhaust setup! I should advertise for them.

My 98 TransAm was rated at 305hp and it was dead on. I was upset with the power so I bought an exhaust system to correct the problem. It then dyno'ed 325rwhp and 340'ish rwtq. It was super slow without the exhaust, definately felt like a 260rwhp'ish car. The exhaust picked it up another 65 rwhp or so and it really pulled hard, even for an automatic!

RE: LS1
The brand of headers really doesn't matter, they all do the same thing. Just different fitment and quality of materials.
I got a nice boost of power from my exhaust work, went from 13.38 @ 105 to 13.16 @ 108, in slightly warmer weather even. On a worse 60 ft (2.13vs 2.18). And no tuning.
Weather is cooler today, gonna try for a 12.999 tonight.

what did you add exactly? headers, midpipe, catback what brand? that sounds like something a lot of ls1 owners can benifit from, or are you just saying in general that happens all the time with all ls1's no matter what

I've seen manual cars make 350rwhp with the same setup as my car at that time, and even more than that with a good tune slapped on it.
My cars very well documented, so if you have any other questions, just ask. I know you're kinda skeptical about them.
