The Ford Mustang ranks as one of the best-selling and most popular American sports cars ever made. Since the mid 1960s, few cars have defined muscle car industry quite like the Mustang. While early Mustangs allowed few modifications and upgrades, later generation Mustangs – including the 6^th generation models – provide plenty of opportunities to enhance stock factory components.

PFYC, your headquarters for do-it-yourself Mustang projects, has a comprehensive assortment of your favorite Mustang parts. From exterior aftermarket accessories to under-the-hood components, you’ll find everything you need for a late generation Mustang upgrade.

Our Mustang parts experts here at PFYC receive many questions about DIY projects, and one of the most common involves exhaust components. From cat-back to axe-back systems, Mustang owners (just like you) are interested in better performance and, in many cases, better sound.

While Mustang exhaust upgrades are considered a high-priority project, there’s an argument of sorts with Mustang enthusiasts about which brand of exhaust system is better: Roush vs Flowmaster.
