Hey guys I'm getting a custom exhaust done this week and I'm ordering tip for them to weld on. Does anybody know off hand what the biggest outlet diameter the r53 exhaust cutout can be? I thought I saw somewhere that two 3-3.5 inch tips would fill the gap pretty well. Anybody can confirm?

I have the magnaflow exhaust with the trumpets, I believe the trumpets go to 4 inches, which just fit inside the cut out, but mine are exposed about an inch form the cut out. the diam pipes leaving at 2.5'' and easily fit. I would say the 3.5 tips will be fine
