Right to the point...is there any way to know what brand mid-pipe is installed on an '08 G37 Coupe? It has Berk HFC and a MeganRacing axle-back, but I don't believe MeganRacing makes a cat-back for the coupe. So how can tell what brand the mid-pipe is? Yes, I'm sure it's not stock. It has smaller resonators and a noticeably larger diameter. Thanks in advance.

 

Unless it stamped on it's difficult to say. Can you post a picture? Megan Racing does make a Y-pipe for the G: Megan Racing

 

This is the only pic I have. The left is of the stock. This right is the aftermarket.

 

looks like a megan muffler

 

Yeah, the tips say "Megan Racing"
