Ok a buddy of mine is a welder at the Honda plant here. He wants to make a custom CBE for my 11 WRX to see how it goes and if he want's to sell it. I don't have a problem with it at all but what I would like to know is what would be a good set of mufflers to use? I'd like something that will work well as a quad tipped and I'm also going to suggest that he buy a flex pipe to help with the fitment. Thoughts? Suggestions?
Edit: My car is his test car and I will use it for a while, may keep it but may buy a nice exhaust still too.
