well i got my car dynoed over the weekend with the x pipe, not tuned. last time it was 263 and 288 sae and 269 and 298 std. with the x pipe it was 269hp and 295 ft lbs sae and 275hp and 305 ft lbs std so about 6hp and another 10 ft lbs. i will have to double check the dynos later but i beleive these are correct numbers. also last time the mph was like 132 and this time it was 114 i think at peak power... this week my wheels and tires will be here. next week ill be addin hopefully the k&n CAI for some better response, maybe a few more ponies?
