RPM Performance Hyundai i30N / VN / Kona N Flexi Pipe
Built for performance. Handmade in the UK from premium stainless steel and TIG-welded to perfection.

Upgrade that matters
The factory flexi is one of the biggest choke points in your exhaust, it narrows down to just 50mm. Our RPM Performance Flexi maintains a full 76mm (3”) bore throughout, improving exhaust flow and unlocking gains of 8–12bhp. Pair it with a GPF delete for a complete high-flow system.

Performance and sound
By freeing up the exhaust flow, your turbo spools faster, throttle response sharpens, and you’ll hear a slightly deeper, more aggressive tone — especially on overrun.

No warning lights
Designed to work seamlessly with factory sensors — no EML or tuning required.

Easy installation

Direct bolt-on replacement. No cutting, no welding. Supplied with all necessary bolts and ready to fit. Introducing our Hyundai I30N / VN / Kona N Flexi pipes, made out of stainless steel, professionally TIG welded and handmade in the UK!
