For those familiar with the version 2 this is the new and improved version 3 Performance Exhaust.
Performance. Quality. Sound. Durablity. Affordable!
The SILA Concepts Performance Exhaust Systems have become the most popular performanace upgrades for the smart.
The goal of this line of exhaust systems for the smart was to offer the smart owner a great quality, trouble free exhaust system that would offer a higher level of performance over the current systems, a nice sound that is throaty, but at the same time not as loud as other competing units and lastly durable.
We have been very pleased with the nice sound, great quality and the added performance we have felt on our own smart after installing this unit.
