whats best size exhaust piping?
what would be the best size exhaust piping for an o7 tc. most of what i see is about 2.5 in for the inlet. is this fine or will it reduce the backpressure too much and will i lose most of my bottom end torque? and does anyone have any experience with the ebay exhaust systems or the srs exhaust?( i'm kinda liking that exhaust right now) if so do they bolt up easily and have a decent quality about them. just trying to get something for my car and don't want to spend the huge amount of money for the name brand axle backs.

One of Megan Racing's strongest products, the Cat-Back System is made of SUS-304 Stainless Steel with a fully polished surface, CNC machined flanges and mandrel bends. Its aggressive styling, and deep, strong tone are just part of the MR Cat-Back characteristics. It also serves to improve horsepower, torque and overall performance with its straight-through design. The exhaust systems have 2.5” piping and 3” piping for certain forced induction models. Finished with a tip that is designed to increase the scavenging effect and achieve maximum performance, while adding a perfect match on exterior styling as well. As a direct bolt on, each Cat-Back comes with a 12-Month warranty.
