🔧 Service Completed: Custom Cat-Back Exhaust System with X-Pipe

At MIJ Exhaust Ltd, we recently completed a custom cat-back exhaust upgrade on this Dodge Challenger 2009 5.7L Petrol, giving this iconic American muscle car the powerful V8 soundtrack it deserves.

For this build, we fabricated a bespoke cat-back exhaust system incorporating a custom X-pipe, designed to improve exhaust flow, balance the exhaust pulses, and enhance the character of the legendary 5.7L HEMI V8. The result is a deeper, smoother, and more aggressive exhaust note with increased presence under acceleration, while still maintaining a refined tone during everyday driving and cruising.

The custom system not only unlocks more of the HEMI’s unmistakable V8 sound but also complements the Challenger’s bold muscle car styling, delivering a performance-focused upgrade that looks as good as it sounds.

As with all of our custom exhaust work, the entire system was fabricated and installed in-house using high-quality materials and precision craftsmanship, ensuring outstanding fitment, durability, and a professional finish throughout.

We’ve got a full video of the completed installation along with a sound demonstration, so you can see the finished system and hear exactly how this Dodge Challenger now sounds.

Check out the video and let us know what you think of this HEMI Challenger transformation.
