Testpipe Q?

[AIRPATEL]

Hey guys thinking about getting a testpipe for my A4, but i want to know if its worth all the trouble. I know i have to figure out something for the CEL. I currently have a magnaflow catback. Are there any suggestions on TP brands? Will Revo Stage II help for the CEL problem? Do the defoulers work?

revo turns off ur chek engine light i beleive.... get a test pipe.. i have 034 test pipe... its great...

[AIRPATEL]

do you have the CEL with the 034 TP?

[AudiA4Turbo22]

all test pipes will give u a CEL, u need to use either a spacer or a software like REVO or APR to delete the CEL!

[AIRPATEL]

I currently have revo stage1, do i need a reflash or go with stage2??

[AudiA4Turbo22]

u need to go to where u got flashed, and tell them to put the CAT delete file in takes like 10 min!

have the 034 test pipe, make a very noticable difference, but i do have a cel, just got my fauler from vast need to put it on

I just installed my ER TP yesterday that I had sitting in my garage for awhile. I know some have dyno'd TP's and showed little or no gain, but I can def feel a difference in how the car drives. I have the stock exhaust so sound didn't really change, but the turbo spools up alot sooner and peak boost seems to come on sooner/stronger.

I used the defouler (since I didn't feel like The $50 to reflash the Cat delete code; I'm REVO Stg 2). One small and one long (both non drilled, just enough to fit the sensor). So far no CEL, even with a little ideling; only time will tell though.

i bought the $112 dollar ebay test pipe and i am very satisfied with it. goin on 6 months now.... exhaust note is just what i wanted!! here's a vid... http://www.youtube.com/watch?v=ZNL5tDJSKNc

the biggest thing i noticed was EGTs went down a bit and also when idling, EGTs returned to normal operating temp much much quicker than before... good for the oil im sure

What if I have the GIAC chip/flash, would I still have to have the code taken out? And what is this spacer you refered to?

[AKA47]

where did you get the defoulers from? is it hard to install?

[old guy]

Easy peasy: Clicky click Remove rear O2 sensor/install spacer/re-install sensor.

Just got a group buy going today for the 034 Test pipe or HFC!

I've had a TP for over 2years and no CEL using a spark plug non fouler from autozone. The revo 2 file automatically deletes the code anyway.

i have giac and they do not offer the cat delete,so thats y i went with rai testpipe it has the j-bung, no cel at all.

Test pipes cause bad karma and other negative consequences. Go with a HFC instead.

What consequences do you mean?

[trev718]

I don't know about bad karma and negative consequences but it does produce a bad smell...

A bad smell?? Hell no that straight fuel smell is the best lol. A bad smell would be if the cat was still in there and everytime you step on the gas it smells like shiz. atleast if your behind your own car smelling it while you step on the gas. haha

I dont have a cat but after I run my car hard and come to a stop sign or a traffic light I smell it..Dont know if it's a mixture of exhaust and testpipe but I dont really mind....

I've got an 034 test pipe. Very well crafted, as well as a metal tube can be crafted.

APR tuned so I don't have a code. My butt-dyno likes it.
