Evolution X! This exhaust is the next generation just like the EvoX is to the EvoIX . To achieve our objective we did not sacrifice on the 3 most important things; Sound, Looks and Power. This means being able to keep exhaust note tolerable and exhaust gas velocity high. The result is true High Performance Stainless Steel 3 inch exhaust system that is polished to a show quality from the flange to our muffler which has been complimented with blue heat treated tips. Expect 6-10 whp from the catback and 30-40 whp with full turboback.
