Bob, You can see the power levels in my sig or in my thread here.
While their is torque loss down low, it's not as dramatic as my charts indicate because they started the dyno at different speeds.
The exhaust adds a good amount of horsepower in the peak gain but the non-peak is where you feel the most. I don't have any air intake, just 4.10 gears and exhaust. I don't have a performance tune on the car and it was run on 87 octane. SAE correction of course.
Read my thread.

My first test was at a stop light and before with my 295 tires I could chirp a little but that was it. After the exhaust, I could lay tracks through the intersection. Opening the exhaust helps the mid range but as you can see really opens up the exhaling at higher RPM's where it is producing more gases.
I hope to get my intake stuff on this summer and then I'll do another write up. I am doing the parts in stages and starting with exhaust because I searched for two years and didn't find an exhaust only dyno.
