The stock, rhombus wide-tip exhaust is pretty unique but not very powerful. Swtich it out for the HKS Hi-Power dual titanium tip center mounted cat back exhaust! With a 3.8in diameter tip, this muffler reduces the exhaust pressure by 50%! This allows the turbine to run smoothly at low RPMs which improves overall output. With tuning, the engine output can increase up to 500hp without power loss.
