HKS Hi-Power 409 Exhaust Mitsubishi Muffler

Removal of left side rear traction hook is required for installation of this product.

The Ultimate High Spec Muffler Designed For 1000ps.

HKS has developed one of our most powerful muffler. It's for horse power of 1000. It's for R35 GT-R with HKS GT1000 RACING SPEC. We purely pursuit the exhaust efficiency for super low exhaust resistance pressure. 
The RACING MUFFLER pipe diameter is φ101.6 and didn’t have to narrow down. It connects to the main pipe by changing from the 2nd catalyzer so that we didn’t have to limit the diameter of the pipe because of the stock flange part.

For over 40 years, HKS products have been put to the test in drag racing, road racing, rallying, and top speed trials. HKS equipped vehicles have captured numerous racing championships and hold claim to a myriad of competition records using many “off the shelf”, race proven HKS components. As a result, HKS has been synonymous with “performance” in the automotive aftermarket industry for the past 40+ years.
