I dyno'ed my S with and without the test pipe. The results were nearly identical.

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.

Did you ever find any of those dynos? I would like to see one....I put the test pipe on and it made the car alot louder...(i already had a spugen TI exhaust)...im not sure if the car got faster or just sounds faster!!!!!!

More importantly my Greddy goes in tuesday, so i have to decide before then if the test pipe stays or goes before my dyno tune on tuesdasy!!!!! HELP!!!!!!!

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.

Oh, BTW, the green bar, was without the test pipe. Red was stock, and the other two are with test pipe, and tuning.

Oh and the last thing, 7 HP for $200........ and people are ripping it? That is not a bad return for the dollar.
