09 M45x exhaust

[agreen1982]

Hey guys
I have been reading posts for days now and I can't find information for my specific year/model.

I want to remove the restrictions in my exhaust, maybe even make it a true dual, leaving stock resonators, cats, and mufflers. I really hate the section where everything comes into a single pipe then back to dual again.
I'm hoping it sounds a little meatier and maybe get a little more performance.

Stollen has a cat back system, which would be great except it only goes up to 08. The other exhaust systems I have seen, which are few, don't work with the X / ATTESA

So, I'm a little lost. I could handle finding someone to do a custom true dual, but is that going to cause performance issues? Am I just being crazy thinking those pipes would do better not X/Y'ing together and apart again?

Why don't you just do a muffler delete with bigger diameter piping. Cheap and sounds a whole lot better!

Why would it be different then a 08? Stilled is retarded cause they say there exhaust for a 45 won't fit a 35 and it will. They just sell 2 different stock numbers to keep track.
