This catback not only sounds great, but also improves exhaust flow with the included Y-pipe for an increase in rear wheel horsepower and torque.

This Stainless Works 3" Retro Chambered Cat-Back with Y-Pipe is specifically designed to fit the 2015-2017 EcoBoost Fastback Mustang and will require the use of a Stainless Works 3" Performance Down Pipe in order to be installed properly (see drop down option above).

Amazing sound for Ecoboost

The sound of my Ecoboost now is very very nice, it's not too loud to wake my neighbour, but it's definitely loud enough to impress a beautiful chick that I saw on the street. I would for sure recommend ...

I have the whole turbo back and it sounds good. Will never make that sweet V8 sound but hearing the turbo helps excuse the 4 banger. Louder than I was expecting but you can take it easy and it's fine, ...

Does it come with the downpipe?

JamesS

  • No, The Stainless Works Cat-Back Exhaust w/ Y-Pipe for the 15-17 EcoBoost Fastbacks will not come with the Down pipe in this kit. We do offer the down pipe in the drop down section to add to your order which we offer both catted and Off road. Catted: https://www.americanmuscle.com/stainlessworks-catted-downpipe-sw-2015eco.html Off-road: https://www.americanmuscle.com/stainlessworks-or-downpipe-sw-2015eco.html

It says with SW Downpipe. Does the 3 inch downpipe come included with the purchase of theexhaust?

JamesS

  • The Stainless Works Cat-Back Exhaust w/ Y-Pipe does not include the Stainless Works 3 inch Down Pipe. It is listed to show that it is specifically designed to work on 15-17 EcoBoost Fastbacks with the SW 3 inch down pipe already installed.

Is this a full 3" system with the downpipe?

Could you please tell me how much the sound difference would be between the catted downpipe and the off-road downpipe?

CarlDawg

  • The Stainless Works Cat-Back Exhaust w/ Y-Pipe - Fastback (15-17 EcoBoost w/ SW Downpipe) is a great system. The off-road down pipe will be much louder and will crack and pop more as you are down shifting then the catted downpipe will.

i notice this says it comes with the SW ( stainless works im assuming) downpipe but there is an option to add a cat-back or off-road exhaust. the package details dont mention a downpipe either so am i missing something? if it does actually come with a downpipe then what type of downpipe is it? thanks .

Erik

  • The part at the end in parentheses (15-16 Ecoboost w/ SW Downpipe), means this is for use only in conjuction with that Downpipe, that's why there's two in the drop down menu. It doesn't come with it, that's a part you have to get to go with this.

    I have the whole turbo back and it sounds good. Will never make that sweet V8 sound but hearing the turbo helps excuse the 4 banger. Louder than I was expecting but you can take it easy and it's fine, really let's you know when your mashing the skinny pedal.
