      Get the Cat Back. When you’re looking for an exceptional exhaust upgrade for your 2018-2020 Ford Mustang GT Fastback, then you’re going to love what Corsa has to offer. Their Xtreme Cat-Back Exhaust with Black Tips is built to give your Pony better flow and superior sound in any situation, be it on the road or the track.

      Superior Construction. This kit is forged directly from high-quality 3-inch diameter stainless steel. It provides superior resistance to corrosion and road hazards. The mandrel bending process used in making this exhaust ensures that the piping stays completely straight and un-pinched, so your exhaust flows through completely unhindered.

      Black Tips. Your exhaust sounds amazing, but something that brings the looks together from your exhaust is the tips directly at the end. And on these 4-inch tips, you’ve got a deep, shiny gloss black finish, further improving corrosion resistance, while giving your Mustang serious muscle car feel. They’re given valves as well to adjust the tone of your exhaust.

      Installation. You will need either jack stands or a car lift to get to the install site. This should take about 4 hours with the use of hand tools and moderate mechanical experience. If you lack either, please have this installed professionally.

      Limited Lifetime Warranty. This cat-back exhaust is protected by a limited lifetime warranty, defending against material and manufacturer’s defects. Please see Corsa’s full warranty for more details.

      Application. This Corsa Xtreme Cat-Back Exhaust with Black Tips is designed to fit 2018-2020 Ford Mustang GT Fastback models with Active Exhaust. Please ensure correct model before purchase.

        Sounds amazing, but with annoying rattle.

        Sounds amazing. Super loud on track mode, and quieter than stock in Quiet mode. That said, there is a terrible rattle coming from the valves when in Normal or Sport. I've triple checked tightness on all clamp hardware. After reading up on this on other forums, I'm not the only one with this issue.

        Cords Xtreme Catback

        This system was built with great quality, install went smoothly, and although I had been reading about issues with alignment on the cords system, I did not run into any issues. Now how does the exhaust sound? This exhaust lives up to the name -Xtreme- I was not expecting it to be this loud, and when I open the valves (track mode), it sounds almost as loud as my 2011 camaro ss (with Long Tube Headers!) but when I am just driving around, cruising, I leave it in quiet mode and the car is as silent as it was stock. If you have the money, 10/10 would recommend

        Love the sound

        Loud and proud! Even more so when paired with catless long tube headers. However these do not pair right up to Stainless Works headers. Both meeting points are 3". Some modification was required.

        Best system I've heard

        This is by far the best sounding exhaust system I've heard. Very high quality, sounds amazing by itself and even better when paired with Corsa headers. Installation was a breeze with the very detailed installation instructions and fits perfectly. No regret buying this at all.

        Corsa Extreme

        Sounds amazing, Track mode is way louder and Quiet mode is better than stock. Resonators came with dents from shipment but can't be seen installed. Took sometime to level the tips (few adjustments) but now its perfect. Feels quicker and lots of smiles at 7500rpm...

        sounds mean, worth every money for it, if your deciding between sport and the extreme and you have the active exhaust its basically 2 in 1

        Can't ask for more

        My 2018 GT has the active exhaust feature which actually helps with not waking up my wife at 5am. The Corsa Extreme definitely gave me the sound I was looking for and more. Once headers are installed I don't think quiet mode on the active exhaust is going to do much sound suppressing. The exhaust is definitely on the high side of price, But makes up for quality and durability. You do pay for what you get.

      I have a 2019 with the active mode switch can I buy the extremes that font come with active mode and the engine light come on or no?

      Was wondering if I upgrade my factory kit to this, will i incur any engine lights of some sort?

      I have a Airaid race cold air intake, BAMA race tune 93 octane, Pypes Off-road X-pipe, Corsa axle back quad tip mufflers on my 2014 Mustang GT Premium. I was wondering about how much horsepower did it add to my engine.

      • Unfortunately we do not have the exact numbers, but the performance gains will definitely be good.

      I have the corsa double helix x-pipe and now want the xtreme axle back but I only find the sport is the sport axle back with the x-pipe considered the xtreme ?

      • The sports will not be as loud as the xtremes even when paired with the x-pipe.
