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.

FI Res Test Pipes & Catback here and no regrets whatsoever.. Sounds just way too good

I don't know, maybe because of the color (PG) it doesnt show up?

That 5-10 minute warm up I bet had at least a bit to do with it, but that's me speaking without knowing.

Chuck, Simple Green will cut right through that crud as well. Just spray it on when you wash your car. That's what I did with my 350, which had Kinetix test pipes. You might find that easier than using ScratchX.

the tips on the exhaust i had were recessed slightly but stains are unavoidable, just a matter of how bad. black paint really hides the stains the best, white is the worst.

May I suggest a mild cleaner wax instead of the scratch X. The Scratch X is far too aggressive for that frequent of use. There are many milder options available.

Mine is white with Beluga resonated TP's. I have no staining after hundreds of miles with them on.

Test pipes will give you cancer. Be prepared.

I've been thinking ART pipes, should keep a nice tone. Not to mention they have cancer absorbing resonators.

Art pipes create Rasp unless you buy the complete motordyne exhaust. (Per Tony at Motordyne. The computer design Hurlwitz resonated tubes only work with their system)
I love my ART'S mated with my Ti look, Top Speed exhaust. It's kinda loud, but sounds great to me.

Get ones with resonators...

Fixed :tup:

I have the Motordyne exhaust already so that is why I will probably stick to the art pipes. Even though they are expensive.

Obviously the stain is most noticable with white cars. My test pipes stain my bumper very bad. Use Meguiars paint restoration which takes it right off. I have HFC on the way which will hopefully reduce it. The exhaust smell does get annoying at times. I have FI CBE and HFC on the way. Should make my car sound so much smoother although i'll def lose some power going from straight pipes to this

I had exoticspeed on my G coupe with FI RHFC'S , loved the sound only regret was selling two weeks after for some nonsense I was dealing with. Kept the cat back installed it on my G sedan and am awaiting my Z1 HFCs to arrive :) .
