    Will this fit/connect right up to the roush valence?

    Tyler28

    • The MP Concepts GT350 Style Rear Diffuser will be compatible with the Roush models, as these will have the same bumper as the premium trim levels.

    will the Corsa Pro Series Quad 4 in. Exhaust Tip Kit work with this product

    Usaf1105

    • Although the Roush Rear Valance, item 389792 or 387054, https://www.americanmuscle.com/roush-rear-valance-2015.html or https://www.americanmuscle.com/roush-rear-valance-noholes-1516.html (one with and the other without predrilled holes for the backup camera sensors) are recommended for proper fitment, it may still be possible to use the MP Concepts rear valance with some minor modification or tip alignment.

    Why does this product only fit the premium models and is there any solution to getting a GT350 diffuser on a base model GT?

    ThomasG

    • The MP Concepts GT350 Style Rear Diffuser will only fit premium models as they have a different rear end and different mounting spots. We do have the GT350 rear diffuser and bumper that will work for the base models. https://www.americanmuscle.com/mpconcepts-gt350-rear-bumper-kit-1517.html

    I know I have to cut out spots for the sensors, but does this come with a template sheet to do that or do I have to do that by eye?

    Nick

    • It unfortunately does not come with a template sheet to perform that, we typically recommend these bumpers to be installed by a professional body shop, that way there are no errors.

      Gt350 style Diffuser

      The item Fitment was perfect the only thing is when you take it to get it installed make sure they put some type of Special glue to make it stick to the bumber your body shop or whoever puts it on will know..not everything that gets installed fits perfect in makes your mustang look a lot Cool

      Buzzkill

      I just got my diffuser after extra delivery time don’t why it took two weeks also when I opened the box and inspected the pieces I noticed about 5 plastic tabs where bend and broken off the tabs that connect the exhaust pipe panel .. and on top of that I got no install guide and no light panel inserts so I talked to them and told them I already hadn’t to postpone install and that I don’t have much off time . And to my luck I have to wait another week and a half to install my set up what a buzz kill .. completely don’t understand

      Same lower piece for MPConcepts GT350 Bumper

      I bought the GT350 MP Concepts bumper and the lower valence was damaged. After obtaining a spare valence for the premium bumper “only” it does also work as a replacement if you originally bought the MP Concepts rear bumper.

      Rear vallance

      Got the new mod in and it was just the look my pony needed.. I was worried that the texture of it would be heavy and not match the rest, but it was even more smother that the factory's which is a good look!! Very nice !!!! U don't need to pull the bumper to replace it as well ..
