135i Quad Exhaust

thezone135i · 07-02-2016, 12:59 AM

I know this has been done to death but I was wondering if its possible to run a full twin exhaust on the N54 135i? I notice there are some systems that go twin DP'S, twin mid pipes, then into one at a Y joint or resonator and then into a single back box and then split back into 2 to go quad at the rear? Why not just go full twin all the way?

It's been done before by iCarbon but they're no longer around.

So it is physically possible without relocating the battery? If that's the case I could maybe get a custom one made up.
