Just wondering if anyone has installed a test pipe and if so have you gotten any codes? From what I've seen so far no one is getting codes, but i cant understand why they would'nt be. anyone know??

 

how can ultimate racing not get codes when they use a test pipe? i want to know before i buy one. i dont get it. HELP??

 

i know you dont get codes if you use roadracemotorsports.com test pipe, it's got the sensor relay thing on the pipe. WOOT!

 

i'm running with the ultimate racing test pipe. it really does get rid of CEL problems. they showed me how they do it...but i'm not supposed to tell how...
but it's pretty trick how they do it!

 

Even if you get the check engine light from a test pipe, it doesn't make the car run ****ty. Just there to tell you that the 2nd O2 sensor isn't reading a lower than the front one.

I have a ghetto 2.5" test pipe for sale for 40 bucks if anyone is interested. Ran 12.7 at 106mph with it, stock exhaust This one WILL set off the check engine light though.

 

it looks to me everyone likes the ultimate racing 3'' turbo back... sounds nice?? anybody dyno yet ... if so wat is the whp gain? im actually looking for one that will be just slightly louder when cruising ( better sound damn nice though ) and OPENS up like a beautiful monster on full throttle.... also is it true that the test pipe ALONE will drop your boost 1 psi but keep your same power ratings therefore allowing more hp/torque when boosted back up to stock settings with boost controller?

 

I have a 3inch test pipe from RMR for sale.. Pm me

 

Im running a test pipe and cat back exhaust will someone clue me on the big secret so i can get my Service Engine soon light off. PLEASE

 

I've got the Ultimate 3" S.S. test pipe and I'm getting tired of looking at the CEL. Any info would be greatly appreciated.

 

c'mon guys. help us out here. what is the secret??

 

How is it that you have the cel on when you installed the test pipe from Ultimate! I just installed mine today and no cel at all. I resetted the ecu once everything was installed and fired the car up. Idled for few minutes and went out for a test drive with a few WOT runs. Still no cel! I still need to do more driving on th Evo for few more days to see if the test pipe from Ultimate really gets rid of the cel.

 

Check engine light will not immedialtely come on. It will take a long continuos period of driving to set it off. ECU gives the car time to reach optimal tuning before it starts checking. Mine did not come on for days of stop and go traffic. Took a little highway trip to set it off.

 

thats becasue of the nature of the emissions testing system in the ecu, it will only test for the rear O2 on long trips where rpm
s are held steady adn vary little. For the non believers who think the CIL will not affect powergains please explain why Dave Bushur lost HP when dynoing a stock EVO with a testpipe. Freer flowing exhausts usually gain power not loose power.

 

I've talked to Dave on this subject and your right it does throw a code --i have his system in now with a testpipe. But I have not ever heard him talk about losing performance. As a matter of fact I asked him when i bought the system if i should use his test pipe or his high flow cat (i have both) and he said Ill get a little more power with the test pipe. I just wish someone would speak up about Ultimate Racing's CEL trick.
