Are people still having problems running test pipes? I know there is a problem with the 02 sensor, but has that been fixed?

I should upgrade to a HFC or a Test Pipe soon so any information would help. How much louder does the test pipe make the car?

Thanks,

Matt

The test pipe will making the car a little louder but not that much.

nobody has reported back yet.

does it make it have more power ro spool up faster?

Fairly significant. But in my experience it's not a bad thing. And yeah, the CE light is something we all learn to live with. No biggie.

second CEL is just cosmetic, and i will find an emulator to wire into the 2nd O2 line.

Sound wise its not much louder than stock cat. I went from a Borla/oem cat to a milltek/test pipe. The sound got deeper, and pretty. Nice thing about the T28 kit is you get that intake sound as well, so if there is droning, i don't notice it.

Power was significant. I have OneEight's test pipe. I went from spool up at 3500 rpm to spool up at 3000 rpm. Granted that was between both the test pipe and bigger exhaust, but 500rpm drop in spool in nice...and now 5-7k screams.

Id recommend either OneEighth's HFC or test pipe...good stuff. You will be happy with the performance boost, the lower boost onset, and the sound really is nice.

Will it fit up to the stock Downpipe? I just have a supersprint exhaust and that only replaces the middle plumbing + muffler.

Where did you buy it and how much?

Thanks for the info

I Can sell you a downpipe for your supersprint and a test pipe if your interested.

i have a 3" to 2.5" test pipe with O2 bungholes.
