I just bought this car and I'm trying to get it in shape. The car does not have an exhaust system... Period! Believe it or not, it's not that loud but it's running like crap. I was told that with no exhaust it's not getting the back pressure it needs to run correctly. I'm having a system put on next week, to the tune of $600 but does it really make the much difference in the way a diesel runs?
