HKS Super Turbo Muffler -

A straight structure and there is no restriction
The exhaust pressure is 30% less than that of the stock exhaust system, and Super Turbo Muffler could be meeting about 500 horsepower.
Commitment to sound quality
The combination of the silent chamber and special silencer reduces the unpleasant sound. You can enjoy a powerful sound when you are accelerating.
