Here, you are looking at the HKS Hi-Power Exhaust for the 2002-2007 WRX/STI.
This catback will fit both Sedans and Wagons without an issue!
Inspired and designed from endurance and GT racing in Japan, HKS developed its Hi-Power Exhaust system for turbocharged applications. HKS has incorporated this new race-inspired offset muffler and piping design into many street applications, which offers a greater flow and higher PRM power gains due to the less restrictive design. This is achieved by eliminating unnecessary bends for the straightest exhaust path.
Does not clear on vehicles with optional Subaru skid-plate (rear differential).

Paired this cat back with a tomei elh / up pipe and grimmspeed divorced downpipe (catless). With the HKS cat back the car is still tame at idle but sounds awesome when getting into the throttle! Not to mention it looks great!

Ordered this exhaust to have something a little more tame compared to my nur spec cat back. This exhaust is perfectly balanced being that it isn’t too loud at idle but sounds good when driving or doing pulls without being overly loud. I paired this with a tomei equal length header and grimmspeed divorced downpipe (catless). This was my 3rd cat back and I finally achieved what I was looking for in sound! Highly recommend for daily drivers
