I had the Berk pipe on mine and tripped a cel in about 50 miles. Reset the ecu and the same thing happened. Sold the tp cause I couldnt stand that damn light. Bought a Megan pipe and the 42002 antifoulers and havent had a cel now in probably 2000 miles. Makes living with the Invidia much easier as well. Cut way down on the drone and makes the ole butt dyno happy!

 

Yes! I agree, a test pipe eliminates the drone on the invidia! It's great now.

 

i had a t1r testpipe with a custom made o2 sensor i bought off a VW forum b/c i have the older version of the testpipe which made the o2 sensor stick out at an angle, so if i would have gone over a speed bump my o2 sensor would have been broken off completely. never got a CEL with the anti-foulers i had on there for a while nor the custom o2 sensor mod. love the sound of it and the increased power. i took it off a while ago for inspections and immediately put it back on b/c i just hated the feel w/out it.

 

Why? It's illegal in most places, up to 10,000 fine and possible jail time if caught with one, and gains are very minimal.

 

Ok, went to autozone and bought total of 4 spark-plug anti-fouler but didn't need but 2 of them. Drilled the hole just big enough for the o2 to fix through the anti-fouler....then screwed it back into the testpipe.....went for a test drive about 65miles and still no cel yet and hope it stay that way.

 

Don't.!!!Save the planet.

 

my bumper is starting to turn black... i'm going to get some clear bra for the rear bumper to protect it from setting on the paint...

 

i just installed a birk test pipe today yes i can actually feel the difference, nice mod and nice sound on a 3500 to 4500 rpm sounds like i have a new exhaust... cheap and nice mod

mod on a car
04 arc induction box and chamber
birk test pipe

add hp dont know but the difference is there

oh btw i think im getting use to the smell

and i hope that s not true up to 10,000 dollars fine WOW
people let me know how much do you really get fine for running a car without a cat. i lived in los angeles

OH THE ANSWER IS YES GET ONE....

 

I have the CT SC, CT exhaust and Invidia test pipe and I have no complaints.

 

My testpipe experience was not as positive as others. My rwhp went from 378 to 381 and torque remained the same. Throughout the mid and high rpm ranges torque suffered ... peak torque came at 8600 rpms rather than 8200 w/o the testpipe. Also the car felt stronger without the testpipe. Needless to say it is no longer on the car.
