This BOSS is very demanding... He wants more... More horsepower and torque that is.


Nathaniel's trashed the much more restrictive Flowmaster mufflers in favor of much higher flow custom made straight through side pipes. Each pipe has an inside diameter of two and a half inches. After fabricating the pipes, they were sent to Jet Hot to receive the famous thermo coating.
