I understand if you are on a budget and can't afford mandrel bends, but you own an M3. Why not spend a few extra bucks on pre-fab bends so your exhaust dosn't need to be re-done later when you want more power?
I appreciate you wanting to mod your car, but from a fabricator's view I'm not impressed given the caliber of car you did it to.
Does the stock exhaust piping use mandrel bends..in looking at the rear section the pipe looks like pancake city?
