I'll start this by saying that I'm going to get to Cobb Stage 2 eventually...
I'm going to install a gutted OE uppipe and a Cobb downpipe with cat. I've researched all of this and these are what will fit my needed the best.
I currently have a Borla Hush catback. I'm was and am looking for something throaty but not loud.
I just recently noticed that the Cobb downpipe ends in the stock 2.5" donut gasket. (Dumb, I know.) Cobb says that a 3" system is better blah blah, but I think that a 2.5" setup with a Prodrive axleback would be just fine, especially for stage 2.
So, what do you guys think? Stick with the Borla or sell it and get a Prodrive oval tip axleback? I'm interested in both performance and aesthetic thoughts.
