update on exhaust issues... can anyone help?

[mn box s]

calm here, not trying to be a dick, another .02 I see blue2000s...

Any way thanks edevlin I also tried extending my 02s and putting them farther down the pipes. So you are saying put the 02s back in the stream up front? Edevlin did you have a wandering idle?

I would also like to add to the people who don't seem to understand why so much work to stay this way. I have absolutely NO resonance at ANY rpm! also can barley here the exhaust with the windows up unless really on it.(hard top) From out side though it is a beast, plain and simple. One last thing it makes whopping power over having cats. I have not dynoed yet but by seat of pants and runs against a testing car gave me 4 car lengths 60-100 mph. I will say I'd bet I might have lost a little bottom end before 4k rpm.

Testing car 03' M3 with exhaust. Before the exhaust and intake he dissapeared into the horizon. After intake, and exhaust (M3 was in sight!) headers (8 car lenthes!) test pipes and no cats ( 3-4 car lengths back and locked up!) I'm hoping after re-programming that I'm even. Who here can take an M3 with exhaust? What have you done? Sorry about the long post.
