        will this fit a 2015 convertible?

        Will this fit on a Cobb 3” downpipe

        • It will not. This catback has 2.25 inch in diameter piping, so you will either need an adapter, or a new downpipe with that size piping.

            Excellent experience

            It’s always difficult to make a purchasing decision on an exhaust purely based on customer reviews and video clips. I trust the Roush brand and American Muscle community and therefore purchased the Roush cat back exhaust system through American Muscle. The set up arrived within a few days. Unfortunately the wrong tips (chrome instead of the ordered black ones) were in the package. I was afraid this would cause a problem and that I would be caught in a holding pattern forever when calling the American muscle hotline. I was wrong. The folks on the phone were very knowledgeable and helped me out in no time. The black tips arrived a week later in perfect shape. Now to the installation. We installed the exhaust in our garage and it took less than 2 hours. Taking out the old one was easy. Installing the Roush exhaust takes a little time since it has multiple connecting pipes that need to be properly aligned before tightening all clamps in order to have the tips be perfectly aligned. When we started the car up, I was unbelievably impressed with the sound. Its not a V8 rumble, but I did not expect a 4 cylinder being able to sound that great. It has a deep tone and some popping when getting if the gas. Not obnoxiously loud, but enough to make a statement. Overall very impressed with this product.

            Great Choice!

            I spent several weeks looking between different exhausts to try and find the one that was not too loud but still had great tone and definition. I arrived at the Roush Cat-Back Exhaust and this exhaust is perfect, it is pretty loud but you can still hear the turbo when accelerating so it was a perfect fit for me. I highly recommend this exhaust! Also there for me there is not too much crackle and pops when accelerating, if you are trying to show off and rev your engine then there will be a crackle once you let off. The black tips accent my triple black car great!

            Hard to say how I feel

            The Roush exhaust is crazy loud. I can’t say that I would have bought this with a sound clip to hear it but I’m past that now. It sounds rather good but concerned about the total insane loudness during acceleration. I can tell a difference with the new exhaust in what feels like a bit better performance. Will probably buy something different at some point in the future. Overall it’s a solid exhaust with high quality materials and I am happy with my purchase. I also installed the Roush cold air intake and it is also very nice, they work well together and my mustang sounds like no one else around lol. Anyway thank you Roush and American Muscle.

            Deep, loud, and satisfying!

            Roush never fails to disappoint. I was a little skeptical buying this first since I couldn't find any audio clips, but I'm so glad I pulled the trigger on this beauty! If you're looking for high quality stainless steel build and a nice deep satisfying growl for your ride, then look no further. Roush fan for life.
