I'm stepping down from a 400hp killer 1998 Trans Am amped up on Tq. I'm am happy with the V6 - hell with the car overall!. My family/associates remained baffled why I didnt go with the SS. I don't need it. I use to think I did till i got comfortable in the v6. Only thing I felt i would be missing was a richer sound. You guys have sold me on this exhaust.

I don't think you will see much gain at all, at least not in PEAK HP/TQ. There will be some small gains more in the mid-range. it's more like the 6 to 8 range.

We did a before and after on my car. We cut the mufflers out and replace them with a couple of resonators.

Here is the result:

I'm guessing the bottle neck at the higher RPMs is further up stream... cats or maybe heads...

That is my opinion... YMMV...
