BMW M3 X-Pipe Midpipe 2008-2013 | WSTN Performance (S65 E90/E92/E93)

The S65 V8 screams. This midpipe lets it. The BMW E9x M3 is still one of the greatest driver's cars ever made. The S65 naturally aspirated V8 4.0 litres, 414hp, and a 8,300rpm redline is a sound and experience that no turbocharged engine can fully replicate. The factory midpipe, however, muffles what the S65 is capable of producing. This WSTN Performance X-Pipe Midpipe with Dual Resonators replaces the OEM unit with a straight-through X-pipe design that balances banks for a fuller, more even exhaust note while the dual resonators retain enough refinement for street use. stainless steel, TIG-welded, built for the demands of a high-revving V8. Built to order, quality checked and sent from Perth, dispatched worldwide. Why Upgrade? ✅ X-Pipe Configuration: Cross-pipe design balances exhaust pulses from both cylinder banks producing a fuller, more layered V8 exhaust note than an H-pipe can achieve. ✅ Dual Resonators Retained: Keeps some refinement intact for daily driving less rasp, more tone. Aggressive enough for track, liveable for street. ✅ Free-Flowing 304 Stainless Steel: Straight-through design improves exhaust flow across the full RPM range of the high-revving S65. ✅ Precision TIG-Welded Construction: Every joint is TIG-welded to 304 Stainless Steel stainless engineered for heat cycles and sustained high-RPM driving. ✅ Direct Bolt-On: Replaces OEM midpipe at factory mounting points no fabrication or cutting required.
