Anyone put M3 dual rear exhaust on a E90 328i?

I heard there was some back-pressure issues, but didn't know if someone has tried it?

Shouldn't be any back pressure issues, get one and I'll make it fit.

Let me know what you end up doing with the rear trunk + gas tank thats in the way on the right side which will cover it up!

Most of the ones I've seen on 328's just run an extra pipe from the muffler on the drivers side over to the passenger side. No need to fit 2 mufflers.

+1 Or they change the muffler to 1 in and 2 outs and custom the piping so one runs longer and goes out the other exit with dual tips on each piping to do quads.
