Downpipe, Cat-Backs and Engine Management! What you need to get you moving!

GST has what you need!

TiTek Catless Downpipe
TiTek Innovations fully polished stainless steel downpipe for the 02-07 WRX/STi are offered with a straight flow design through our smooth bellmouth transitioning to our full 3” mandrel bent finishing. This downpipe will help increase horsepower by maximizing exhaust flow efficiency. This item is an easy bolt-on upgrade for stock and upgrade turbochargers for horsepower gains.

GReddy Racing Ti-C
GReddy Racing Ti-C Cat-Back Exhausts combine the design, looks and flow of GReddy's Full Racing Titanium systems with the durability, deep sound, value and large application list of GReddy's other Stainless Steel street systems. This fusion of aggressive styling and practical construction, makes this the logical choice for both Race and Street Enthusiasts. The systems are comprised of a Titanium heat-treated tip, polished stainless steel muffler, unpolished stainless steel piping. It improves high and mid-range performance while still allowing for suitable sound levels when used with the included tuned Tri-mounted Silencer.

Apexi NOIR
So you want a stealth exhaust? You don't want a large can hanging out the back of your STi? Well Apexi has the answer for you. Apexi's new Noir exhaust system is based on the same design style as their World Sport system just sporting a Matte Black finish. This is a great option for anyone wanting to keep things subtle or for those wanting to be different. The NOIR Exhaust has a straight threw design making it ideal for the WRX/ STi Turbo Charged engine.

And the always popular HKS Hi-Power cat-back systems
HKS Carbon Ti
Special Edition HKS Carbon / Titanium Hi-Power Exhaust systems are available for certain popular applications. These exclusive versions of the Hi-Power Exhaust consist of a carbon fiber wrapped stainless muffler shell, a 120mm titanium tip, and polished stainless steel piping.

HKS Hi-Power
Inspired and designed from endurance and GT racing in Japan, HKS developed its Hi-Power Exhaust system for both turbocharged and naturally aspirated 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.
For turbocharged applications, the large and smooth exhaust flow allows greater exhaust velocity for better mid-range boost response and high-RPM power. Hi-Power Exhaust systems are made from SUS304 stainless steel muffler and tip assemblies.

RS*R Ex-Mag
Sleek in design, this exhaust system's unpolished 304SUS setup maintains its subtle look while increasing horsepower. With the street enthusiast in mind, this system's mild tone hides the performance gains that many would normally believe are unheard of from a system looking and sound like the Ex-Mag. Designed for the street, the Ex-Mag is ideal in gaining horsepower throughout the entire power band. Its modesty is sure to surprise many, providing performance, style, and sound for every daily driving performance vehicle.

Invidia N1 Exhaust
Engineered with advanced technology, Invidia uses computerized mandrel-bent to give the exhaust the straightest possible line from the cat-back to the tip with the least amount of bens, CNC machine flanges for strong solid support, and robot TIG weld for piping, performance mufflers, and tip to improved strength and durability.
Has a resonator, flex section, and comes with a removable inner silencer to reduce noise levels.
