Do you have access to ISTA or OBD code reader to cross check that there isn't an error code that don't trigger a CEL yet?
How does it sound compared to stock DP? |

The sound, well it IS louder but since I have the M Performance Exhaust with the automatic flap control, if I put the car in "comfort" mode, the sound is mellow (a little louder than with the stock DP) but if I put it in "Sport" and combine it with "Sport mode" transmission, it roars. I will try and do a video and review this weekend. |

AlexGT , it could be the reason. US spec tend to require stricter emission control. But as I mentioned, it is a hit and miss. I just came by ER yesterday and they told me again that it is not guaranteed.

Nice, please post more sound clips of Downpipes with or without cats and include the vendor/brand of the downpipe!
I'm curious of soundclips with just replacing a Downpipe and stock or MPE exhaust. Curious to see if they are all pretty similar in gurgling on throttle off. Who's got the best sounding DP ?? |

AlexGT, I just remembered that you have RaceChip Ultimate installed on your car.
Does it have an auto CEL/DME Errors clean like JB4? That may not give evidence of no CEL with stock not tuned ECU... Would it be possible to test ER catted DP without tune to cross check that all is OK with stock ECU? Best would have been a long term evaluation of several thousands kilometers... Thanks in advance! |

I'm going catted because i dont want the CEL and dont want the bad gas smell. I know I will lose a few single digits hp/tq versus going catless & not as loud but hey thats fine with me. Going to add the ChargePipe too. Getting K&N drop-in filter wanted to get injen intake but none fit lol & N20 might not need it unless I had upgraded turbos. So this week K&N drop-in, then trying to see if I find a good price for CP and DP and have the Dyno shop do runs before and after mods.

I recently installed the AR Design catted down pipe and absolutely love it. Noticeable power increase, sounds amazing and no cel in over 500 miles.

Not that I know of. They claim to have tested both sizes and supposedly saw better gains with the 3". I just went with ar due to the fact that they are a reputable company with a slightly less expensive product.
