Once I get the car on a lift, I'll be able to see whats really going on down there...

I'm envisioning cutting the stock muffler out, putting a 'Y' pipe in, and having two 3" pipes lead down to some straight thru Magnaflow or Aero Exhaust mufflers, going back to the stock tips.

this is how the N55 OEM exhaust is.
drop'd my exhaust last night and installed the Vanguard Exhaust.
that's one way to save money, bmw. ty.
