Description

Get that flagship flat 4 rumble with the HKS Racing Muffler. This muffler has been designed with minimal bends that help reduce exhaust turbulence under acceleration which promotes more horsepower, more torque, reduced turbo lag, and a better throttle response. The larger piping diameter combined with the racing style muffler produces an aggressive tone under boost, as well as under idle.

Exhaust hangers are welded onto the OEM locations so that this exhaust system becomes a direct fitment without the need for any further modifications. Gaskets, as well as hardware, will also be included to make this racing muffler ready for installation.

    Answer

    Shouldn’t this fit my 2004 wrx STI? It shows that it does not but I thought if it can fit 2005-2007 it should fit on my 2004?


    • A: This exhaust is also compatible for the 2004 WRX and STI.

  • Q: pipes and diameters  Lark_thelandshark 11 months ago

    Answer

    Is the taper at the start of the midpipe designed to mate up to a stock downpipe or an aftermarket 3in downpipe? And is the coated piping stainless steel or mild steel?


    • A: The taper seen in the photos brings the exhaust down to 3 inch ID, this is designed to mate up with an aftermarket 3 inch down pipe. The exhaust material is 409 Stainless Steel.
