Post BPM CEL log

Posting info.

Any CEL issues before?
How often between lights coming on?
System...GT, MKiii, TT?

Have you removed the first O2 in the pre-turbo cat?

I am getting one every 75 miles or so..

Does no one own this exhaust or are you all having no problems due to the second cat removal?? Tried disconnetcing the first 02 sensor in the upipe (from the harness) and it didn't work either. What about those of you running the venturi? How did you get around your CELs? Does anyone want a 4 day old BPM Turbo-back GT setup?

Wouldn't you like to put an OBD to it first!? You don't know, as of yet, what the cause of your CEL is. OBDII codes are emission related, for the most part geared toward the concept of prompting maintenance of your car before it becomes a gross polluter. You may be getting a light for something as simple as the exhaust temp being higher than it was getting before the cat was removed. Are you concerned for the safety of your car? The light annoys you? Or, worries that you wont notice a prompt of some other condition due to the light already being on? I'm curious, what was your reset method?

Yeah, I really don't feel like taking the car to the dealer and saying can you pull the code for my emission problem because I put an aftermarket exhaust that should have been R&Ded already?

Does anyone in the western PA have an aftermarket exhaust and a check engine light? I'd be happy to pull the codes for free. You just have to get to Pittsburgh. I sell some performance parts and really want a heads-up on this problem. Thanks Brian

ANY car repair shop that handles imports should be able to pull/clear your DTCs. It should only take a couple of minutes to do.

Anyone in the chicagoland area who needs a pull PM me. It takes me about 30 seconds to hook up my laptop hit INIT, and hit REQUEST CURRENT TROUBLE CODE.


Of course for your first born I can hit the button that says CLEAR CURRENT ENGINE CODE hehehe.

Seriously, I've heard of my fair share of people having CEL's after putting on the exhaust, but even more people who have NOT gotten a CEL ever.

Perhaps your CEL is coincidence to something that would have happened anyways?

I've got the TT exhaust, and my CEL came on after 20 miles w/new exhaust. Haven't taken it back to installer yet. Will do tomorrow.

Wayne, I've placed an order for exhaust sytems with MRT and I have some BOV's coming to, maybe a flywheel or two. Should be another couple weeks til I have it. I have one exhaust sold and will follow it closely. The question is, Should I reset the ECU and see what happens or not reset the ECU and see shat happens? Hmmmm! BTW, we are sponsoring an import drag race on June 2nd. You at least have to come visit, I really want to meet as many fellow i-clubbers as possible. Thanks Brian

If you are not using one of the O2 sensors, don't you have to do something special to it, to fool it into thinking it's seeing correct readings?

I think it would be best to start pulling codes and reporting what they are before tossing blame about.

AFAIK you can purchase little devices to hook up to your OBDII computer for not alot of money(~$300) to pull codes and clear CELs.

-OBD Scanners more than I remember.

1. You guys need to get the actual codes (duh).

2. Even if you replace the front O2 with a resistor or something the ECU will think you've got a bad cat as it monitors the delay in readings between the two to measure cat effeectiveness.

Therefore, you need an exhaust system that keeps both sensors. Or a smarter way to fool it. End of story.

Are you telling me that the BPM exhaust does NOT use both o2 sensors?? Than they are misrepresenting the product! I was assured that all the stock connections are retained, and this is a strict bolt-on affair (needing only a gasket). This is a real problem. Can an owner verify if you have a disconnected o2 sensor?

I got a call today from BPM, (thanks Greg) They are very serious about helping us all solve this problem with our U.S. cars and he is going to try to send me some double gaskets and other stuff....work in progress. I have been pretty happy with the Hp gains, and we'll get the whole CEL thing solved sooner or later I hope.

So we can try to get some consistancy. What exactly have you done to your car (what brands, etc. for everyone who has posted? I am running a K/N panel filter, 5sp, and the GT. I was running a Greddy MBC at 14.5-15psi before I started having problems and have since removed it to try to isolate my CEL problem.

The BPM set up does not exclude any of the sensors.
People with cel issues should pull codes and post their results; outside of that, there is no way for us to make any real discovery from this survey. I don't have a CEL with my MKIII so I am unable to help in this. You can buy an OBD interface for ~50$ and I have posted many free applications for graphing and analyzing output.

I also got a code on me TT after about 200 miles. I had my dealer (Thank you Carr Subaru) and it was a cat thermal efficiency error. A buddy of mine has my car right now, and he reset the code for me, and it has not come back after 160 miles. BPM has been very responsive through all of this.

I have another question regarding the CEL issues with BPM exhaust. Please list if you did or did not get the CEL, and if you did or did not reset the ECU after installation.

BPM TT system

1st check engine 140 miles
reset ecu
2nd check engine 250 miles
reset ecu as we speak
3rd????i will post.

I have the O2 on the lower bung near the stock location, and have not touched the pre cat turbo.

BPM needs to do something about this, or should have done something about this.

I know of 2 others with GT system and Check engine lights in intervals that have not posted yet.

I have ITG panel filter, 5 speed, joe p mbc set at 14psi, BPM TT system.

I had no cel with itg and boost controller since i installed them, but cel after installing BPM.

Im at 375 miles on my second ecu reset and no code.


edit- is it possible that bpm meant this exhaust to be ran with there venturi pipe. now that i think of it, it makes sense that they have 2 O2 bungs on the downpipe, one for stock exhaust O2, and one for pre turbo pipe O2 after venturi pipe install, therefore both O2 will read consistent readings. is this theory off?

just an idea. im sure its irrelavant.

first ce light: 125
second ce light: 240
third ce light: _____?

I have not recieved an email from bpm yet.

i will try contacting them.

EJ20WRX,

The only relevant information you might be able to post is the Diagnostic Trouble Code that is the reason for YOUR check engine light. Until you can report what your code is, you're just flailing in the dark (and wasting everyone's time).

BTW, DTC P0420, in the absence of any other codes relating to the O2 sensors, generally means an exhaust system leak and the inspections consist of checking for gas leaks or air suction caused by loose or dislocated nuts and bolts, as well as checking for actual holes in the exhaust. Make sure your gaskets didn't get wrinkled/crimped during the install and that you've properly torqued the bolts and nuts connecting the piping together.
