Porsche Boxster S 2003 - MIJ Exhaust Systems

Service Completed: Custom Twin Centre Exit Rear Section Exhaust

At MIJ Exhaust Ltd, we recently completed a custom twin centre exit rear section exhaust for a 2003 Porsche Boxster S 3.2 Petrol, giving this iconic sports car a more purposeful rear-end appearance and an exhaust note to match its performance pedigree.

For this project, we fabricated a bespoke dual-exit rear section exhaust, replacing the factory rear section with a handcrafted system designed specifically for the vehicle. The exhaust was finished with twin centre exit tailpipes, creating a clean, symmetrical look that complements the styling of the Porsche Boxster S while adding a more aggressive, performance-inspired finish.

Manufactured entirely in-house using premium-grade stainless steel, the new rear section was built to ensure precise fitment, excellent durability, and a high-quality finish throughout. The bespoke design also delivers a deeper, richer exhaust note, enhancing the unmistakable flat-six soundtrack while maintaining excellent drivability.

Every custom exhaust system we produce is tailored to the individual vehicle and fabricated by our experienced team using precision welding and expert craftsmanship. Whether you’re looking for a custom rear section, centre exit exhaust conversion, stainless steel sports exhaust, or a bespoke Porsche exhaust system, we manufacture every exhaust to the highest standard.
