Next Friday I am off to CKS for a cutom built exhaust for my 335d. I have not decided yet on the exact system as I donlt know the current set up of the stock systems.
What I do know is I am deleting the 2 rear boxes for sure.
What I don't know is if there is a center box too after the CAT. If there is I may delete this too and go straight through pipes form CAT back....as long as it not boomy or too loud
Otherwise I may Go CAT back and replace the center box and do the rear delet only.
Anyone have any suggestions or experiance of this ?
