I'm pretty sure someone asked this question before but I'm going to ask again. Those of you who have TL-S w/ Comptech exhaust and header, DO YOU FEEL THE DIFFERENCE IN HP or PERFORMANCE? Has any one taken to dragstripe to see what it does on 1/4 mile & 0-60?

I'm very very curious how big of difference the modification makes on performance. Its suppose to add over 30HP at the wheels.

Your input will be greatly appreciated.
