Achieve uncompromising performance with the ETS Cat-Back Exhaust System designed specifically for the EVO. Engineered for maximum power gains, this system combines 3.0" or 3.5" mandrel bent stainless steel piping with a high-performance Vibrant Performance muffler, creating a winning combination of performance and aesthetics.

Starting at the cat, the ETS Cat-Back Exhaust System tucks closely into the driveshaft tunnel, ensuring near factory ground clearance. As the piping expands, it reaches a full 4.0" diameter before meeting the 4.0" muffler inlet. The exhaust then exits through a 4.0" tip, tastefully angled at 15 degrees. This setup not only delivers a race-inspired appearance but also offers exceptional high-performance capacity.

Installation is a breeze, utilizing the factory rubber hangers and including all necessary hardware. With its precise fitment, the ETS Cat-Back Exhaust System ensures an easy and painless installation process.

Experience the ultimate combination of performance, aesthetics, and ease of installation with the ETS Cat-Back Exhaust System. Elevate your EVO to new heights, both in terms of power and race-inspired looks. Trust in the quality and expertise of ETS for an exhaust system that delivers unmatched performance and sets you apart from the competition.

The downpipe-back version of the ETS 3.0" or 3.5" Exhaust is for serious race vehicles. This exhaust totally replaces the cat and bolts right up to your stock or aftermarket 2-bolt downpipe. This takes full advantage of the 3.0" or 3.5 €� diameter piping and gets the transition even closer to the turbo for maximum horsepower capacity.

Great sounds great materials

Great fit with jdm rear bumper. Exhaust sounds awesome no raspy sounds just the beautiful stainless steel exhaust sounds. Not too loud but not too quiet either

Love the build quality and sound

This was the best exhaust system I could get for my car and I am overwhelmed with joy on how badass it looks and sounds

mack harris

it make good sound easy install would recommend changing the rubber stock mounts to urethane since your there anyway

Great Sound & Fitment

Super happy with the 3.5” version’s fitment. Was expecting it to hit the tunnel or the DSS center carrier CV joint. It clears everything with room to move. Flanges are way better than the typical flat plate the is usually welded on. ETS sent me the right sized gasket, and nuts/bolts/washers and slip-fit clamps to make this a quick and easy install. Only thing I could ask for is an option to add a rear O2 bung plug for those of use not using a rear O2.

I highly recommend this exhaust. The sound is deep and does not have any rasp to it. Definitely more quiet than the hood exit exhaust I had on the car. Won’t have to worry about noise ordinance as much as before. Don’t get me wrong, It is still quite LOUD at WOT.

    This item is plug and play meaning you can bolt it right up to your factory catalytic convertor.

    The catback in Stainless weighs approximately 28lbs with hardware and clamps, the factory exhaust weighs about 37lbs for reference.
