most aftermarket downpipes have a flat flange. Cat backs designed to hook up to the stock downpipe maintain the stock-like doughnut flange. I had this issue with my catted helix downpipe and borla hush CBE. It's not a big deal though. Exhaust shops do this kind of work 10x a day every day.

Well.... I have solved this dilema by ordering the Cobb DP. I just ordered it today through www.xtremerallytuning.com Josh from there was very helpful. I emailed him to see if had any deal and he created a sale for me. I got the Cobb Accessport and Cobb DP for $1150.00. I just ordered it today, so, i will let you know how i like it. I tip my hat off to XRT who responded quickly and gave me, what i think, is a great deal.
