After reading the posts I thought I understood what I needed to do. When I looked at the stock mufflers and compared them to the BC Preds I was more confused than ever ?
The stock left side muffler has a built in bump stop. The Pred dose not .Is this were the little black oddly shaped piece comes into play ?
I also noticed that the mounting holes on the mufflers were not the same ? The stockers are round,and the Preds are well not round ? I figured that I needed to remove the rubber inserts from the stock ones and use them on the Preds ? Not so. *** !!
Have a look at a few pics I took.
The only other question I have is. When you mount the mufflers up to the down pipes do I need to seal/glue them ?
