The MXP axel-back exhaust for the 08+ Subaru WRX is made from T304 Stainless Steel.  It reduces exhaust restriction by using a larger diameter piping, yet still remains under legal noise levels. This is the perfect exhaust for the daily driver.

MXP branded exhausts are made of the highest quality of stainless steel available. The grade of stainless steel is SUS304, which is slightly thicker than a competitor exhaust system that is offered on the market.  Though a thicker exhaust may have a slight added weight value to it, the extra thickness helps improve lasting durability and performance for the long term. MXP exhausts are significantly lighter than OEM exhaust systems. Together with the added thickness for durability, and light weight reduction, MXP exhausts will bring out more performance for your vehicle.
