Xtreme Aggressive Sound. Be heard long before being scene by installing a Corsa Performance Xtreme Cat-Back Exhaust System on your GT Mustang. Acoustically engineered and tuned, this Corsa Xtreme Cat-Back will give your 5.0L V8 Mustang a throaty, aggressive sound under acceleration and a deep growl at idle, all without any annoying drone while cruising. An Xtreme Cat-Back Exhaust is ideal for those GT Mustang owners who don't care if they wake up their neighbors. As an added bonus a Corsa Xtreme Cat-Back will also improve your Mustang's exhaust flow by 43% for an increase of 5 RWHP and 4 RWTQ.Race Car Growl. Corsa Performance Xtreme Cat-Back Systems feature a very unique double helix X-Pipe that replaces the factory resonator Mid Pipe. The double helix "X" crossover design not only helps improve exhaust flow for an increase in power, but it also adds a crisp raspy, race car growl to the sound of your Mustang's exhaust.RSC™ Technology. Corsa Performance engineers all their mufflers using their very own patented Reflective Sound Cancellation® Technology (RSC™). RSC™ Technology is designed to give your Mustang's exhaust an aggressive sound under acceleration and a drone-free experience while cruising.Quality Construction. Corsa Performance proudly manufactures their Cat-Back Exhaust systems right here in the good ole USA. This Corsa Cat-Back is mandrel-bent from 3" diameter, premium grade, 304 stainless steel tubing for excellent exhaust flow and enduring corrosion resistance. The system includes a double helix X-Pipe and two high flow, straight-through Xtreme mufflers. The mufflers feature a pair of black chromed twin 4" Pro-Series tips. Step down flanges are included, so that this 3" Corsa Axle-Back can be installed with the factory 2.5" exhaust.Application. This Corsa Xtreme Cat-Back Exhaust System with Black Chromed Quad Tips is designed to fit 2015-2017 Fastback GT Mustangs equipped with the factory Premium Chassis Package (Trim Levels: 400A/401A) and the 2018 Fastback GT Mustangs that is not equipped with the Active Valve Exhaust System.

Will these have any negative affect on emissions? I live in California and don't want to have to deal with that sort of thing. Also I have a 2018 GT with a Performance Package that already comes with stock Quad tip exhausts so will these fit without any issues?

RageZ3R0

  • The Corsa Xtreme 3 in. Cat-Back Exhaust will install after all of the factory emissions equipment, making this legal for California Smog testing. One thing to check into would be local exhaust volume regulations, as this can vary greatly across the country. This should have no issues working with your 2018's valance since you already have quad tips.

will it fit the V6 if the premium bumper cover is installed on the car, or are there any other complications?

17V6

  • Unfortunately, the Corsa Xtreme 3 in. Cat-Back Exhaust is designed for the 15-17 GT Mustangs. This Cat-Back may not bolt up correctly to a V6. Thus requiring modifications for proper fitment.

Why it’s 1637 dollars here but it’s 1718 dollars in corsa’s website. I just wanna know what’s the difference?

MasonG

  • The price of this Corsa Xtreme 3 in. Cat-Back Exhaust will fluctuate depending on when you are looking at the item, but this exhaust will be the same if you purchase it from AM or Corsa directly as long as the part number is the same.

Hello, I have a 2015 mustang gt premium, I have 2 question's 1. Will this quad tip fit a rear valance that has 8-8.5 inch opening for the tips? , and 2 does the dual tip and the quad tip corsa extreme sound different?

marios

  • The Corsa Xtreme 3 in. Cat-Back Exhaust will have two 4" tips slightly spaced to come to over 8" in overall width. Unfortunately we cannot confirm if these would fit your valance as we do not know if the openings are properly spaced to line up to this without more info. The quad tip and standard Corsa tips would sound virtually identically.

    No regrets!

    These sound fantastic and the black polished tips look sharp. The exhaust note is loud with no drone and when you get after it, it has a shrill exotic burble to it. Sounds a little "raspy" like the GT350... but wayyy better than any exhaust I have ever had. I've had the system installed for only a week and I've already had dozens of comments at red lights about how "absolutely wicked" my car sounds.

    Corsa Xtreme quad tips

    Replaced my borla stype catback with these new corsa Xtreme quad tips, they sound awesome, extremely loud but quiet when cruising around. They really have no drone at all the noise is behind you, I also have stainless works off-road headers. These will definitely get people's attention. Plus the quad tips really separate the look from single tip exhausts.

    Amazing system!

    I've had this exhaust on for about 8,000 miles now. It is most definitely broken in, and I couldn't be more impressed! I look forward to going to work everyday and listening to the cold start. My girlfriend always comments how she can hear me driving off every day well after I have left the neighborhood. I do a lot of highway driving and there is absolutely no drone. Step on the gas, and be prepared to hear a beautiful deep tone with hints of an exotic growl behind it. Down shifting/rev matching, you're gonna get every bit of a loud note you could want. As far as install, was right around 2 hours, ran into a hiccup when I broke the stock rear hanger taking off the stock exhaust. Other than that, no issues. Took a little tweaking to get the tips exactly straight and where they needed to sit. Overall, I couldn't be happier with my purchase.

    Loud but in a good way

    First off, I have Stainless Works catless long tubes installed already. So I can't contest to the sound before long tubes. I switched from an MBRP Race and glad I did. The MBRP Race had a deeper muscle car/V8 tone due to the H pipe. It sounded good at idle and lower rpm but had some drone and started shaking my interior apart after the long tube install. Decided to go with Corsa extremes. Since install, the drone is gone and the interior no longer rattles. The Corsa does have an exotic higher pitch and at WOT it starts sounding more like a v10 than a v8. I love the sound, it is intoxicating. It is stupid loud when I want it to be and whisper quiet when I need it to be (except cold start lol). The fit and the finish were top notch. Over all, I am happy with my choice to switch.
