Amazing Sound Upgrade
Louder than stock but in a good way - aggressive and sporty. Noticed a bit more power, but maybe its just placebo. It arrived quicker than I expected with all parts in perfect shape. Great buy!

Looks Great, but Quieter Than Expected
The fitment was not too tricky, but had a few moments of uncertainty. It was just a matter of lining everything up right at once before tightening. The sound is fantastic, it has the deep growl I was looking for, but It is definitely a lot quieter than I imagined for a cat back exhaust. At highway and constant speeds I can hardly hear it. When accelerating, it is there, but not all that impressive. The truck is so quiet stock that I guess it makes sense. The look is phenomenal, I love the dual tips. Overall I would expect this exhaust to be cheaper for what it provides being that Roush pretty much specializes in Ford, but I am still satisfied with the little bit of performance.

Great Product
I chose Roush because of the quality that I expected. NAILED IT!! I read reviews on many products and listened to many sound clips before choosing this system. This was a super easy product to install and I would say the install took about 1 hours to 1 1/2 hours and that is pushing it. Great sounding kit, I would recommend this product. Larry H.

Amazing
I’ve had this exhaust for about a year on my Ford Focus SE, it has a really loud yet deep tone to it and I get a lot of compliments and people wondering how my car can make that noise it pops a lot sometimes even giving me multiple loud backfires the only downside is highway driving because there is a lot of drone something I’ve gotten used to and nothing a good radio can’t fix.
