Anyone with HFC or Test Pipe regrets?

I've had my Berk test pipes, as well as my Invidia Gemini exhaust installed for 1200 miles now. At first I thought it was a little too loud, but now I actually enjoy the tone and volume just fine. I'm 47 years old so I'm a little more conservative than I used to be.

I have no discoloration on my bumper, and have even moved the tips further in so that they are about 3/4" from being flush with the bumper and still no discoloration. The smell is not an issue. You can tell a difference, but it is certainly not as bad as some make it out to be.

I have had to reset the ECU four times so far due to the CEL thrown. The first time was at 97 miles after install. Second time was about 245 miles more, third time was after another 450 miles and this last time just at 200 miles. I'm not too worried about this either because at some point I plan on having the car tuned at Uprev and they say that they can permanently disable the secondary O2 sensor reading to the ECU.

At idle and cruise the car almost the same volume as stock. Under mild acceleration it sounds fantastic! At WOT throttle acceleration it is quite loud in the cabin but still maintains a great tone.

All in all I'm very pleased with the exhaust note and that it has increased performance a little.

I hope that this helps.

Tony
