Hey guys and gals,
Here is another option....
Add a set of headers on it! DTH just put them on our Yellow smart and they are great! They have given us some extra power and the sound is unbelievable. They are getting ceramic coated as we speak and we will start shipping them out next week.
They did some dyno runs as well and we will be putting those numbers up in the next couple of days (as soon as we get the info from DTH).
While it may not replace a turbo or an s/c it has surely increased the performance of our smart.
If you are considering a header please keep in mind the following:
It will make the car noisier (I believe with the exhaust, headers and intake we ran at 89 db).
The header is being sold for "off road and race applications only"
