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.
We have tested the muffler thoroughly with HKS GT1000 Spec R35 GT-R as you can see above movie clip. We have found out that even with 1000ps over vehicles test there is no power down, and also there was no exhaust pressure rise at a higher RPM which indicates there are room for more.
