Whats labor cost/time to install Flowmaster Exhaust?
I'm thinking about going with a FM Super 44 for my 2000 WJ. Can anyone tell me what I can expect to be charged at a shop?
Also...how hard is it to instal a throttle body riser..and what kind of performance increase can I expect from a K&N Intake, Throttle Body Riser, and Flowmaster exhaust combo?
Any suggestions are welcome!
