BMW i8 Valved Sport Exhaust System
The BMW i8 lacks raw sound from the factory. With Valvetronic's full exhaust system, this has been fixed! To achieve a raw and deep sound Valvetronic utilizes a 2.5 inch construction all the way through the system to the exhaust tip. This uncorrupted piping lens itself to a very enjoyable deep sound experience. You get aggressive shift pops on the changes and aggressive overrun when coming off the throttle. The sound is very enjoyable inside and outside the cabin. Be ready to shock some passersby with how good your i8 sounds!
Valvetronic Designs makes premium valved exhaust systems for a wide range of BMWs. These Exhausts are completely handmade right here in the US, at their facility in Chambersburg, PA. Designed with flow and sound in mind, Valvetronic has made a premium system with improved flow and performance, while offering the flexibility of a valved design. While the performance gains are sweet, nothing is sweeter than the thoughtfully curated sound your BMW makes with a Valvetronic Exhaust.
