Group,
I have done some serious exhaust modifications to my car.
Last year, I installed a set of 1G 3.5 manifolds on my M, this facilitated replacing the catalytic converters as well.
The manifolds fit with no modifications to them whatsoever, use the same gaskets even.
Talk about improved flow.....oh yeah!!

converters (which have since been replaced with Magnaflow 2.25" spun converters)

Exhaust pipe routing...

The LX X-Pipe has also been replaced by a Flowmonster 2.25" x-pipe

The exhaust is amazing....and it can be a relatively inexpensive mod, if planned properly.

No emissions testing here in Cincinnati, but no codes from the O2 sensors, all is good there.

Just think emissions is the only thing they test for now in NJ, thats pretty funny.

Usually on OBDII cars, if the CEL isn't on, you are good to go.
But they check anyway....

I think that's all they do in Jersey now... OBDII. I could be wrong, haven't done NJ inspection since April 2009.

What mufflers do you have installed? I have my OEM manifolds, and cats. I have a custom made x-pipe, and 2 Borla turbo center in/offset out that I'm putting on.

I only have 2 Cherry Bomb Turbo Mufflers at the rear of the car.
Sounds great!!

Do you have a sound clip of your exhaust before and after the manifold upgrade?

Ahh. Oh well. :-/ I still may end up upgrading to the 1G manifolds someday anyway. What kind of difference did you feel after you swapped them?
