This forum has a fairly quick and very useful SEARCH feature. Click on the magnifying glass on the upper right of the forum page (above the log out button). Type in "engine mods" or "aftermarket exhaust" and you should get several discussions on those topics.I bought my Versa hatchback in 2012 new. Its about 2 years old now with about 21k miles on it. I am interested in finding out more about after market exhaust systems and other engine mods. Who out there has a Versa and has done any mods?
I would think this would be a good start to try to get your answers and get any ideas of what people have tried before.
