Please Note: When cleaning exhaust tips, especially the blue tip variants which are made using a heat treatment process which can be removed with aggressive cleaning agents, make sure to use water and only if necessary, a very gentle soap. Never scrub, or use any rubbing or cleaning compound on these tips as the color will be damaged and will not be warrantied.
Stock catalytic converters prioritize emissions over performance, creating unnecessary backpressure that holds your engine back. Our performance catback exhaust eliminates this restriction, replacing it with a high-flowing design that minimizes resistance. Less backpressure means better airflow, stronger acceleration, and a more responsive ride—letting your engine breathe the way it was designed to.

Flashark 2002-2007 Subaru WRX/STI Exhaust System FAQs
Q1: Will this Flashark exhaust fit my specific model year, like a 2004 WRX or 2007 STI?
A1: Yes! This Flashark exhaust is specifically designed as a direct bolt-on fit for the 2002 - 2007 Subaru Impreza WRX/STI (GD chassis). Whether you're upgrading a 2002 wrx exhaust, a 2004 wrx exhaust, or a 2007 sti exhaust, this kit is engineered to fit perfectly on your EJ205 or EJ25 turbo engine.
Q2: How much horsepower can I expect from this subaru wrx performance exhaust?
A2: By upgrading to our subaru impreza catback exhaust + downpipe + up-pipe, you eliminate the restrictive stock catalytic converters. Dyno testing proves this 3 exhaust system for subaru sti and WRX instantly increases 10-20 horsepower and significantly boosts low-end torque. Less backpressure means stronger acceleration and faster turbo spool!
Q3: What exactly is included in this downpipe and catback exhaust kit?
A3: This comprehensive subaru exhaust system gives you everything needed for a full breather upgrade. It includes a high-flowing 3" (76mm) SUS-304 stainless steel catback exhaust, a stunning 4.5 inches muffler tip, a high-performance ej205 downpipe, and an ej205 up pipe. It replaces your restrictive factory subaru exhaust pipes from the engine block all the way to the bumper.
Q4: What kind of sound will this cat back exhaust give my Subaru Impreza?
A4: You will unlock that iconic, aggressive boxer rumble! The straight-through 3-inch piping and precision-engineered muffler for subaru impreza maximize exhaust scavenging. This creates a deep, throaty, and aggressive sound that completely transforms your gd wrx exhaust note without sacrificing smooth gas flow.
Q5: Do I need an ECU tune after installing the downpipe and wrx up pipe?
A5: Yes. While a basic cat back exhaust alone doesn't strictly require tuning, installing the included 02 wrx downpipe (or any 02-07 downpipe/up-pipe combo) alters your exhaust flow drastically. To unlock full performance, ensure engine safety, and avoid check engine lights, a professional Stage 2 tune is highly recommended after installing this downpipe catback setup.
Q6: Is this a catted or catless downpipe, and will it pass emissions?
A6: This Flashark catback exhaust kit features a high-flowing design that functions similarly to a 2002 wrx catless downpipe. Because it eliminates the restrictive factory catalytic converters to prioritize maximum horsepower, please check your local emissions laws. This exhaust header+catback+downpipe up-pipe combo is typically intended for off-road or track use.
Q7: What materials are used in this flashark catback exhaust?
A7: We don't cut corners. Unlike a cheap cat back exhaust, our system is constructed from premium T-304 stainless steel with a sleek mirror polish finish. It features TIG-welded, CNC-machined flanges and mandrel bends to guarantee smooth airflow, excellent fitment, and ultimate resistance against pressure and corrosion.
Q8: Can I install this subaru impreza wrx/sti catback exhaust myself?
A8: The kit is a direct bolt-on upgrade designed for the 2002-2007 subaru wrx/sti gd ej205, meaning no custom welding is required. However, because removing aged, heat-cycled factory subaru headers & down pipes can be challenging, we strongly recommend professional installation by an experienced subaru exhaust kits installer. Installation instructions are not included.
Q9: How do I clean and maintain the 4.5" burnt muffler tip?
A9: To protect the signature heat-treated blue finish on your exhaust downpipe tip, only use water and a very gentle soap if absolutely necessary. Never scrub or use any rubbing/cleaning compounds on these wrx mufflers tips, as it will strip the color and void your warranty. If you choose the polished tip option, it only needs occasional gentle cleaning to maintain its shine.
Q10: Will this exhaust system fit my 2006 Subaru Impreza 2.5i or 2007 Wagon?
A10: This specific catback downpipe and up-pipe kit is engineered specifically for turbocharged models (WRX and STI) with the EJ205/EJ257 engines. It is not a direct fit for naturally aspirated models like the 2006 subaru impreza 2.5i exhaust system. For wagon models (like the 2007 subaru impreza wagon exhaust), minor modifications to the exhaust hangers or tip length may be required depending on your exact bumper trim.
Q11: Why is this upgrade better than keeping my stock 2005 wrx exhaust?
A11: Stock subaru impreza exhausts prioritize emissions over performance, creating massive backpressure that holds your engine back. Upgrading from your restrictive 2005 wrx exhaust (or any 02-07 model) to our mandrel-bent cat back exaust lets your engine breathe the way it was designed to. You get better airflow, sharper throttle response, and a much more exciting driving experience.
Q12: Should I buy this Flashark kit or build a custom catback exhaust?
A12: Piecing together a custom catback exhaust and sourcing a separate 2004 sti downpipe and up-pipe can be extremely expensive and time-consuming. The Flashark All-in-One kit provides a dyno-proven, ISO9001:2000 certified subaru wrx sti exhaust system right out of the box. You get a perfectly matched system designed to work beautifully together at an unbeatable value.
