- Durable construction for street and trail use
- Two exit styles to pick from: Dual Rear Center or Side Downpipe
Fitment

Install
Bolt-on installation with no welding required.
Details
A cat-back system replaces the exhaust from the catalytic converter back. It complements other performance upgrades and gives your LittleBig a sound that matches the lifted look. Pair it with the LBS 3" lift kit and tubular bumpers for the full build.

This exhaust really wakes up the little engine. It has a throatier sound when accelerating and makes the car way more enjoyable to drive.
Thank you! We're stoked that you like the Performance Exhaust System. - Jeff Stay awesome.
The factory exhaust was way too quiet. This one adds a nice performance tone and makes the car feel more alive.
Thank you! We're stoked that you like the Performance Exhaust System. - Jeff Have a great day!
If you want your Smart to sound like it has some attitude, this is the way to go. Quality construction and great tone.
Big thanks from all of us here! Enjoy the Performance Exhaust System. Have a great day!
I wanted something with a bit more character and this delivers. Nice rumble on acceleration but still comfortable on longer drives.
Thank you! We're stoked that you like the Performance Exhaust System. - Jeff Keep it up!
Installed this on my Smart Fortwo 451 and it completely transformed the car. The exhaust note is deeper and sportier without being obnoxious.
So glad you're loving the new Performance Exhaust System! Be sure to tag us on Instagram @littlebigsupply. Drive safe!
