i have the spoon test pipe on my car, and it does sound a LOT better, and throttle response is better as well. As far as gains, not sure, never dyno'd with it on.

I love running the test pipe...clears up weight and exhaust flow. Thats my .02 cents though.

I had a test pipe installed on my car, gained 7 HP, but I have a V-AFC, and he tuned the air fuel mix to compensate. I had 203 RWHP on dynapack stock, then with just V-AFC it gave 210, then with the test pipe it jumped to 217 with the tuning. He said he could have gotten 220, but then I would be around 13.8 AF ratio, a little to lean.
