Do you need a specific bumper for this exhaust or can it fit the factory bumper

Does this require a tuner? The description states "increased performance", if this really added any performance, wouldn't a retune be required?

  • No you dont need a tuner. And its awesome. I love it.

    Rouch Square tips Exhaust

    Product look Great and install rite into factory hangers but it was a bit easier on the removal of factory mufflers to unbolt factory hangers then remove them from mufflers and reinstall back on car before installing new mufflers ... A bit louder then I was hoping for but at highway speed you almost think you had factory muffles on car but from a stop they sound Great !!!

    Just perfect !

    Oh man , I can't be more happy with this Roush exhaust , they look beautiful , I can't resist to look back to my mustang every time I park it . They sound amazing ,what a huge change . Yes , they're loud , but just the right volume for a V6 , like someone mentioned before , any video can't be compared , sound like a really muscle car ... little bit of work installing the rear roush valance, but really worth it . Installing exhaust took like about 30 minutes.

    Pure awesome!

    these are soooo worth the time it takes to install the rear valance. looks amazing and it sounds amazing. just a warning, it is much louder than you would expect. kind of has a rice sound but when you really open it up it sounds beautiful. it is very quiet (undetectable) at low rpm so it isn't annoying when cruising.

    You get what you pay for.

    While looking for an exhaust for my '14 v6, I liked the ROUSH sound the best. It seemed everyone had the round tip setup as the square tip set was more and required the use of the ROUSH rear valance. This part requires removal and cutting of the rear bumper. Because of this it adds exclusivity. This means it is a permanent look unless you replace the bumper. Most people say forget it and go with the round tip as they are a direct fit. Well, spending the extra cash and time installing the valance is well worth it. It is more exclusive than the round tip look. The square dual chambered tips are big good quality tips with a decidedly European look. (Disclaimer: it is LOUD. Any video on YouTube simply cannot convey the volume) That being said, it sounds awesome! There is a drone at low RPM. There is a reall BRRRAAAPPP at 2900-3100 RPM. It sounds FANTASTIC at high rpm! Tha gas pedal now acts as a volume control. It is possible to drive around and keep it down, but when it's Funtime, you can release the sound of ROUSH!

    Roush Axle-Back Exhaust w/ Dual Chamber Tips

    First off, Im a full time student, full time worker and with that being said, Im on a budget. This exhaust system really brings the V6 mustang to life, plus it looks way better then the stock exhaust. Easy Install, the most time consuming part is the valance needed for the tips. The finish product is awesome. I recommend anybody who couldn't afford the GT and went with the V6 this setup, ROUSH can really make great products.
