So I'll be putting a Magnaflow muffler on my 318iS tomorrow and since its only a single tip outlet, I'll need to make it wide enough for these dual tips. When the muffler shop puts it on will they do that, or will I need to have it already done for them?
I've tried using a jigsaw with no luck, as the rear apron isn't stiff enough and just kind of wobbles
So if you know of a good way to cut the rear apron so I can fit some dual tips that would be nice (that's if the shop doesn't do ti for me)
