New exhaust video

[xsport652]

Just put an obd 2 midpipe and a rogue catback on the car. So far I am loving it and it sounds ridiculously good. yes it drones, but only when you are lugging it around 2,000 rpm.

Video audio is kind of blown out. There will be a better video soon.

Quick question though.
My first drive with it on my car was stumbling pretty bad, had no power, and sounded like a wrx. So then I got on it just to clear it out. Now every once in a while at a stop light or just idling the car will miss for a few seconds then run smooth again.
I welded in the O2 sensor on the drivers side pipe pre-cat where it would have been on my old obd 1 midpipe. Then I plugged the post cat bungs with bolts. I checked for exhaust leaks at all the connections and there was no leaks at all. Do you guys think it has something to do with only getting a reading from the one pipe? or the car just has to adapt?

Sounds sick! :buttrock

I'd say throw an X pipe in the system rather than the stock H pipe, and it should clean it up even more.

Thanks man.

Really? where would you put it? before the cats?

Exhaust sounds nice, actually one of the better executed exhaust videos I've seen. Do you have a 6 speed? maybe your just in 4th, but it looks like you are in 6th. Do you have a euro M3?

5 speed, us m3. I have the 5th gear detent problem where the shifter rests further to the right.

Sounds awesome! Did you reset the computer after you bolted on the exhaust?

I think the exhaust sounds great! Also, the video is nice. That is how you make an exhaust video! Inside the cabin, outside, driving slow, driving fast, you showed it all.
