Exhaust work after an inline-six swapped. Went to a 328i. With Borla.
1. Cut the exhaust off the inline-six to fit the chasis.
2. If you could, replace the middle exhaust bracket with the inline-six so you can have them two hangers.
3. Drill holes from the trunk to hold the back exhaust because the mounting are different from the 318ti.
3. Trim the rear lip to make it fit the dual.
4.
If you don't have a tail pipe cutter, go rent one at autozone for 60$? Part # is 27045.
Will upload more tomorrow!
