HKS has taken their time to design a free-flowing exhaust that sounds great. Low exhaust resonance is eliminated with sound tuning from the built-in resonance pipe. They aimed to produce an exhaust system to allow owners to enjoy that great boxer sound and succeeded.

Note: Are you using a stock j pipe or downpipe? If yes, the GrimmSpeed Subaru Stock DP to Aftermarket 3 in. Catback Adapter p/n 077046, is required.

Love it

The HKS sounded awesome on my 16 STi. It has a nice deep, loud exhaust note, but is not obnoxiously loud.

As always, super quick shipping! Had this within a couple days of ordering!

HKS Catback exhaust

Excellent exhaust with a deep growl sound to it, and easy install and easy to read instructions. Very quick and speedy delivery with IIR as well. Quality products and fantastic service.
