TP turns to have rasp unlike the HFCs it's a lot less TP are cheaper but will not pass emission which is not a problem for you you can check some videos to see the difference in sound, but at the end both will give you decent gains and it's up to you when it comes to the sound because some people tend to like loud raspy sounds Quote:
I will say at least 11 with the HFC and 15 for the TP take a look in this thread some gained 19 whp from the HFC High flow cats
