E9X M3 Valved Catback Exhaust

The E9X M3's S65 V8 deserves better than stock. The Tone Valved Catback Exhaust is available in 304 stainless steel or grade 5 titanium, both a significant weight savings over the factory system with real gains in flow, with your choice of midsection: a dual X-pipe for the highest-pitched note we offer, an H-pipe for a deeper noise, or inquire with us about a custom midsection if neither fits what you're after. Choose non-resonated for the rowdiest sound, dual resonated for a nice middle ground, or quad resonated for the most refined note and maximum daily drivability. Close the valves and it drops back to stock-quiet, zero drone on the highway. Every system is custom-made to order for a precise, bolt-on fit.
