Replace the restrictive factory exhaust in your 451 model smart fortwo with the upgraded, performance exhaust system from SILA Concepts!

The SILA Concepts Performance Exhaust Systems have become one of our most popular performance upgrades for the 451 model smart.

This exhaust system offers a high quality, trouble free exhaust system that offers a higher level of performance over the restrictive factory unit. The unit also adds a nice throaty exhaust note, but not one that is too obnoxious or loud.

We have been installing these units at our facility for years and have and continue to use them on our own smart cars. 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.
