The COBB Cat-Back Exhaust System for the EcoBoost Mustang is a direct replacement for the factory exhaust. It comes with a 2.5" adapter that tapers down to be used with the factory downpipe or can be used without the adapter and bolted directly to the COBB 3" downpipe. The system is 3" from the downpipe and splits to two 2.5" sections that each run to a COBB stamped muffler. Engine rumble and turbo noises are amplified but still kept in check through the 10" resonator. Aesthetics are improved from the rear of the vehicle with dual-walled 4" tips featuring the COBB logo.

Attention: The Cat-back does not fit convertible Mustangs. Coupes only at this time.


Ditch the power robbing factory cat-back and utilize the COBB Cat-Back system that boasts a 3" split to two 2.5" 304 stainless steel construction, dual COBB stamped mufflers, and 4" dual-walled tips featuring the COBB logo. As a direct factory replacement with no tuning required, it's a simple way to improve the looks and sound of your EcoBoost Mustang! The V2 Cat-Back Exhaust features a 3" to dual 2.5" configuration which contributes to a much more subtle tone than the original 3" to dual 3" design.

Ford Cat-Back Exhaust Mustang Ecoboost 2015-2019 V2 is rated 4.7 out of 5 by 3.
Rated 5 out of 5 by from Well made, great sound. I put this on my ecoboost a few weeks ago. As I'll be driving down to California, I opted for the cat back. I really like the tone that it adds to the car. Without the downpipe, it still sounds very similar to the turboback in the Cobb video. I recorded some exhaust notes for those who are on the fence. I'm very happy with the sound: It adds rumble and a nice tone with little noticeable drone. It's not too loud, and not "one of those" exhausts. Installation wasn't too tricky at all, and the metal pieces themselves are definitely solid. I'm glad I waited for this exhaust. One note: The instructions included are for the turboback, you will need to save and re-use the sleeve on the catback exhaust. (Picture below.)

Rated 4 out of 5 by from Great Sound and very nice Craftsmanship Great deep sound, not raspy like the other systems on offer. No drone what so ever at any RPM. Welds look awesome and done very well. Sounds great inside and outside the car. Has a nice sound at idle and gets louder the further up the rev counter. Will not annoy your neighbors or attract unwanted attention though. I used the stock downpipe, so sure it would be louder with Cobbs downpipe. The only reason I gave 4 stars though is because the Y pipe after the resonator is super close to the drivers side rear floor to the point it was touching if you hit a bump. I added a two washers to the two bolts to the hanger at the back of the stock downpipe to step it out toward the passenger side, and that gave it just enough clearance to move the whole mid pipe, that the driver side part of the Y will not touch the rear floor under any condition. This may not be a problem the full turbo back, and also stepping up from 2.25in to 3in, I would expect it to be tight. Not a big deal,love the catback system, sound, and would buy again!! Also I installed in driveway on ramps by myself, but a extra set of hands would have been very helpful. Ordered on a Monday night, shipped on Tuesday and received Friday, TX to FL. Was installed on a 2017 Fastback with a 6 speed Manual Gearbox.

Rated 5 out of 5 by from RHD Experience Have had the exhaust on board for a month with Cobb dealer fitting and I very pleased with the result. The sound is much improved (even complimented by neighbors) & is a much better match for the performance coming from the rest of the Cobb package. Nice rumble & no droning on the highway. NB. Matching up to a non-Cobb RHD down-pipe (no Cobb option available) did require some fabrication.
