the rear exhaust box on the 1995 E300D I drive is not upto spec, the PO thought it would be cool to have a 3 inch tail pipe going sideways on it, due to that stupid pipe

1 it looks stupid
2 it makes the exhaust hang lower
3 it rubs the bumper
4 it rattles

is there any difference between the single outlet diesel box and the twin outlet gas one - I personally like the twin pipes. Just thought to ask beforehand
