Dodge Challenger R/T Parts & Accessories

Performance upgrades and accessories built around the Dodge Challenger R/T, the 5.7L HEMI-powered configuration that sits at the heart of the modern Challenger lineup. The R/T balances real V8 muscle with a price point that leaves room in the budget for meaningful bolt-on improvements.

Popular Upgrades

The 5.7L HEMI responds strongly to cold air intakes and cat-back exhaust systems. Borla's S-Type and Flowmaster's American Thunder are the two most-ordered exhaust systems for R/T owners, with the S-Type offering refinement and the American Thunder delivering a more aggressive classic muscle car tone. Eibach and Tein lowering springs improve cornering without sacrificing the R/T's daily-driver ride quality.

What's the best exhaust for the Challenger R/T 5.7L HEMI?

Borla's S-Type cat-back is the top seller for the R/T, producing a controlled but unmistakably HEMI growl under throttle while remaining quiet at cruise. Flowmaster's American Thunder is louder at idle and draws more attention on the street. Both are direct-fit bolt-on systems requiring no cutting or fabrication.

Can I upgrade the R/T's exhaust manifolds to improve performance?

Yes. Long-tube headers from Kooks and American Racing Headers are available for the 5.7L and unlock power gains across the entire RPM range when paired with a tune. Shorty headers offer a simpler install and modest gains without requiring tuning. Pair with Mopar performance components and upgraded brake pads for a complete performance build. All orders ship fast.
