The Evolution system for the 370Z uses the same muffler as the Slip-On system. However, it also includes highflow link pipes with integrated resonators and a crossover tube that replace the entire exhaust system from the catalytic convertors back. Made of high-grade stainless steel, this system is race-inspired with a more aggressive character, louder but still perfectly acceptable for daily use with no droning to ruin the driving experience. There are power gains across the entire rpm range, especially in the middle and high section. If you're looking for most powerful Akrapovič exhaust for the 370Z, the Evolution is the solution. Complete the look with a set of two exquisite 125 mm tailpipes in sandblasted and coated titanium or carbon fibre.
