    Product Details

    Stainless Steel Axle-Back Exhaust System with Split Rear Exit (421127) by ROUSH Performance®. Exhaust System Type: Axle-Back. Exhaust Tubing Material: Stainless Steel. Main Tubing Diameter: 2.5". Exhaust System Sound: Aggressive / Loud. This product is made of high-quality materials to serve you for years to come. Designed using state-of-the-art technology and with customers in mind. It will meet your needs and deliver great quality at an affordable cost.

    Not only does this system sound awesome, it looks great as well! The round tips are made from high-quality 304 stainless steel and are finished with a chrome flashing process, and are embossed with the ROUSH logo on the end. This will let people know your car roars, and lets them know you mean business! Conventional chrome plating uses layers of bonded chemicals to achieve its shiny appearance, which are susceptible to cracking and flaking especially when exposed to high temperatures (like exhaust produces). However, the chrome flashing used in this system is bonded micro-porously to the metal surface, and is as a result impervious to cracking from localized damage. This method of chroming is also resistant to heat color change.

    This exhaust kit mounts to the factory mounting points, and includes all necessary hardware and instructions. This makes for easy installation to get you back on the road in no time.

    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.
