The sounds will be different - CATS are smoother and mellower, no CEL or smell issues. CEL issues may be likely of Metallic CATS and on ones that are less than 400 cell.

I've had both HFC's and TP's. I don't have exact dyno numbers, but I can tell you for sure there is a noticable diffrence betweent the two. The TP's are definately "faster"

This may be brand specific or magazine based bias but SS magazine did a test between the Magnaflow TP and HFC and only got a 1 hp difference. Granted the test was done on a civic Si but they seem to respond to I,H,E mods as well as ours as far as what I can tell from reading.

1% diff between TP's and HF cats? LMAO-it smore than that. And if considering or going FI its even more of a difference. Greddy TT guy on these baords gained something like 30whp with test-pipes over his previous HF cats set-up, search for it if you want-1% my a$$...

Don't buy the HP zhit either. You going to feel the difference of less than 1% gain in HP? yeah right......

The difference in throttle response is more important than the hp. TP's FTW!
