drewny1 Posted April 30, 2012 Report Share Posted April 30, 2012 I am about to buy me a STS and I have a few questions 1. Should I install a sub system in the trunk? And if so, how much trunk space will I sacrifice? 2. I want to put an aftermarket Exhaust system on it to give it that muscle car sound, which brand should I go with? 3. Can 22 inch rims fit without rubbing or sticking out? 4. What are a few ways to increase the gas mileage and horsepower? Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted April 30, 2012 Report Share Posted April 30, 2012 I really have enjoyed the Corsa 14157 system on my STS-V. It has a good sound, looks great, proved to make more hp on the dyno, and appears to have freed up some MPG.
