Replace the restrictive factory exhaust in your 451 model smart fortwo with an 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 is manufactured to high quality standards for many trouble free miles. In addition, this exhaust system offers a higher level of performance over the restrictive factory unit. This version also adds a nice throaty exhaust note, but not one that is too obnoxious or loud.

We have installed and continue to install these units at our facilities for years with excellent feedback. We have and continue to also use them on our own smart cars.
 

Features:

  • Designed specifically for the 451 model smart fortwo ('07-'15)
  • Improved Performance
  • Finely Tuned Sound
  • High Quality Flex Pipe to help reduce vibration
  • High Quality TIG Welds
  • Polished Stainless steel Tip Design
  • Chamber Muffler Design
  • High Quality Stainless Steel Muffler
  • Direct Bolt On Replacement
  • No Modifications Needed - Minor trimming of the lower valance only
  • Full 1 Year Warranty Against Defects

 

This exhaust is completely hidden behind the rear panels and the only thing you will see is a polished stainless steel center exhaust tip.
