CP-E catted downpipe owners...

Doesn't look like there's an problems with the sensor installed wise. I could only imagine it's the actually cat on the downpipe especially if you're throwing that particular code. Ahh sorry to say, I know it's a b**** to pull it off and the downtime on the car.

Tell me about it!! (bang)

Oh well, at least CP-E is going to fix it... (2thumbs)
I guess one must expect things like this to happen when you start altering/modifying a car... (lol2)
 
Downtime? You didn't keep the original parts "just in case"?

Still a major headache with the parts in and out thing, but at least you'd be driving.
 
original exhaust, s*** I cut that crap out and threw that sucker in the garbage. Only kept the first cat in case someone needed a stock cat with less than 10k on it.

I have all my stock parts, but I am not installing the stocker back...its a nightmare. Plus, I'll be leaving on a business trip while the car is down.
 
goind back to stock?

He is not going back to stock. It appears that his downpipe has a bad cat so he has to take it out and send it back to be checked out and fixed if it is.
I asked if he has the stock parts so he can drive the car while his DP is gone.
He does, but he has no interest what-so-ever in going back to stock even temporarily and fortunately does not have to because he will be out of town while his car is out of commission anyway.
 
Folks with our downpipes, thanks for chiming in. I just wanted to jump in and mention a few points.

First of all, we're doing the best we can with what we've got. We're a very small shop in Maryland (not a multi-million dollar company), and we try to meet people in the middle with situations such as this. We're honoring the warranty, and we'll correct the problem. The fact is that most aftermarket companies follow this return procedure, let alone one as small as ours. It sucks, but in the rare case that a downpipe cat goes bad this is unfortunately a necessary evil. Thankfully AutoXRacer has been incredibly understanding, so we thank you sincerely for that!

We also don't manufacture the cats. We tested four different cat manufacturers trying to find the best one for the job, but if the brand we selected is not operating properly then we'd like to know about it so that we can notify the manufacturer so they can rectify their end of things. So thank you for bringing this to our attention immediately! And for whatever it's worth, those cats are not a "Louis Cat," it's a "Kooks Cat", which is sold by Kooks Custom Headers; a very reputable exhaust manufacturer in NY. So it was a quality, name brand cat:

I'd also like to mention that for every person who chimed in here that had an issue with our downpipe, there are dozens who haven't had any issues at all. So I'd like people to try to keep things in perspective. We make one of the most popular downpipes on the market, and I think one or two isn't unreasonable. OEM parts fail occasonally, no?

If we weren't fixing these issues I'd understand the frustration, but AutoXRacer, we'll get you where you need to be buddy (drinks)





It is not a vibrant cat, nor is it made in Canada. The catalyst is manufactured in the US, but the stainless steel used to spin the case is made in Canada, FYI.

I didn't know you guys were in MD. I might have to stop by and check out your shop. I was 100% against a warranty perilous mod, but with you guys being so close, I could always come back if there were any issues.

(iagree)

goind back to stock?

Yeah, what Mid Life said (blah)... (lol2)

Damn, I'm starting to look around for cameras and bugs... :D

The stock piece is more complicated to install, you got the DP, mid pipe, and brackets... More importantly, I'd have to R&R the O2 sensors twice...and seeing how they damage so easily...no thanks (no)

I am already dreading and paranoid about having to remove the O2 sensors...
 
AutoX Don'ty stress so much about the O2 sensor unless you already screwed them up the first time. i work for mazda as a tech at a dealership an i did a nice write up on how to remove the o2 sensors without screwing up the threads. it's a big problem everyone at mazda and any tech thats tried to remove them knows it and by going by my write up in the how to section on how to remove and fix the problem i have removed many o2 sensors since my first and have yet to screw up any threads and this includes using my own car as a guine pig to find the best way. my car had only 4,000 miles on it when i fix my sensors and if i didn't do it write i would have messed up the threads. so try not to stress about that one thing. read my write up use plenty of pb blast or simulair oil and be patient but you've already removed it once so you might need to go out and buy a nice thread caser and tap and die to fix them.

well i live in maryland and i'm looking at getting cp-e's DP only because they are the only ones that use cats and like autox i'm someone that doesn't want to smell raw fuel and have to worry about throwing a cat. code or dtc i ran no cats on my srt4 and i swore i'd never do it again. people fail to relize is that 3" down pipes have been dyno'd with and without cats or running high flow cats and there was only like a 5 HP difference in running a cat or no cat. this was dyno tested and only got 5 HP more without running a cat converter. to me 5 HP is nothing to worry about so i'll go with the cat option.

I installed a turbo x's down pipe on my buddies speed 3 and sure enough even with their second o2 sensor bung being extra long acting like a spark plug fouler three days after i installed it it threw a CEL for cat. effiency. WTF ? I told him he needs to call turbo x's right away and ask them why it's throwing that code when it shouldn't and everything was installed using there crap ass instructions or lack there of. I love cork sports DP and really like the seperated gas flow design but still not sure if i want to go catless cause as of now i want to run a cat. luckly i live in maryland so if i do go with cp-e and have this problem i can easy just drive down there and deal with them directly.

I know this sucks but i've met some guys that work for cp-e a while back and they seem like cool people and they have gotten on here and stated that they're willing to fix the problem so it sucks yes but it's still better then them saying hey tough luck your loss. keep us updated please

Weird update...

I haven't gotten a CEL in a week... What gives? (huh)
I'm starting to think whether I should R&R the DP or not now... I wonder if its temperature related. All the times the CELs have gone off was an in between temp of not really cold, but not warm either... I don't know how to explain it....

I don't know what to do now... I'll give it till next Monday, since I leave for my trip on Wednesday the 12th and I was planning to R&R it on Tuesday before my trip.
 
Auto, I had a CEL for the same thing approx. 2 months in. I reset the ECU and it has never come back. It has almost been a year. Give it some time, I think its just the stock ECU messing with us.

I don't know, I've reset the computer a few times already; when I installed the DP and another time when I installed the TMIC...

I think I might give it more time if I don't get one before I leave...
 
I dont understand why there arent more guys running the Vibrant downpipe-back exhaust with the included cat. It is an option for those guys wanting to have a highflow.

Im not saying its a better setup than CPEs but the CS downpipe with the Vibrant dpback is a pretty sweet setup for the money if you ask me. Two exhaust parts, with a divorced wastegate, hiflow cat, GREAT sound, and GREAT price.

I know Ken was offering the whole TBE package of these two together, at 899 shipped at one point. I just dont think you can beat that.
 
I like the material used on the CP-E's product. .304 stainless steal. No coated like the exhaust you have mentioned if I am not mistaken. I know I paid out the ass for this system, but IMO it was well worth every penny.

Does this include "cheaters" for the O2 sensors or some way to relocate them to the replacement cat?
 
i've seen that vibrant system where it's a dp back exhaust basicly you are buyin a dp back exhaust and they're throwing in a test pipe for free. i just don't know about vibrant as far as their quality. in my experience and this is just mine vibrant is kind of a APC like company. BUT they've managed to stay around when others have gone out of business so that has to say something for the company. sorry to say i won't be the first on that one i'll wait for someone else to do that and i like others better. as of now corksport has the largest system out there at 80mm converted to inchs if my converter is right thats 3.14 " 's just slightly larger then 3" but i don't think that makes that big of a difference.

I was at the drag strip this past sunday and there was three speed 6's up there running Cp-E turbo back exhaust aLL has single tips. two were cat-less and one was catted and all have had theirs for about a year now and all said they've had no CEL's at all even the ones with no cat's. they sounded very very nice i might ad. i need to take a ride down there and check them out they're only like thirty minutes from my house.
