I'm pretty sure this is Big Timms custom DP. Does this DP throw a cel since the cat is at the back of the DP instead of right after the turbo? Anyone know the answer?
Almost 2k miles and no codes yet. The high flow cat is about where the stock 2nd cat is. The first O2 is about where it is stock and the snd O2 is behind the cat on the other side of the flange (After the flange to the rest of the exhaust). I think if I were to get any codes, I would have had one by now. Also, $800 built and installed for a 3" SS mandrel bent turbo back exahust is a good price.
Oh yeah, you can dirve the car with no front O2. It goes into speed density mode and drives just like stock......outside of boost of course. I drove it home with no 1st cat because it was siezed in teh pipe and they had to break it to get it out. But the car drove perfectly fine, I could boost, but there was no power in boost. The ECU is a very smart piece of equipment. Now if the O2 was giving incorrect readings, then it would probably have bucked and carried on because the ECU would be trying to tune to the car based on the incorrect readings.
I'm going to talk to the guy that made it and see if he wants to make a jig. I don't think mine will bolt up to the stock ssytem since it was all made at once. They extended the 2nd O2, so it is further back in teh exhaust then stock, so that means the DP is longer. I still have the stock setup, so I'll see if he wants to do anything.Bigg Tim,
I have to say 'Thank you'. This is exactly what I've been looking for in a down pipe. With this setup you can swap out a cat for a test pipe (provided you add another flange).
What's the chances you could get another made and ship it to me?
Since CPE doesn't listen, i'll go elsewhere.
