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.
Quoted from Dsport Test samples -- With the growing popularity of the Scion FR-S and Subaru BRZ, MXP has engineered an aftermarket exhaust system to enhance the performance of these new platforms. Offering a dual muffler exhaust system with burnt tips, the MXP system is constructed from thick gauge SUS304 stainless steel for improved durability. MXP states its exhausts to be do-it-yourself friendly, including crush gaskets for a better seal and carefully engineered components to ensure a pain-free installation. For this evaluation, we examined an MXP prototype of the exhaust featuring chrome tips and only one adjustable tip. Production units will feature dual adjustable burnt tips to accommodate special fitment needs for a variety of rear bumper and diffuser designs. The test unit weighed in on the heavy side at 40.8 pounds, adding 2.3 pounds over stock. However, changes to the materials and design of production units could result in weight losses. On the dyno, the MXP system overshadowed its scale figures with peak power of 176.13 whp at 7,000 RPM and peak gains of 13.33 whp over stock at 7,300 RPM. This was the second highest improvement in horsepower noted during testing. Off the dyno, the MXP exhaust produced an average sound level of 87.67 dB (3-5,000 RPM, no load). The MXP design incorporates refinements such as hollow hangers, TIG welds and a cast divider that splits the flow of exhaust to the dual muffler system.
