The S58 is one of the newest platforms we support, and what better car to do it with than a fully optioned out G80 M3 Competition xDrive! The saying “downpipe and tune is all you need” cannot be demonstrated better than on this car. The S58 just thrives once you open up the exhaust, and easily produces 700whp with mostly stock hardware! This car intrigued us so much in the platform, that we went and got a M4 Competition xDrive as well. The M4 however, will be going beyond the stock turbos.
