I was wondering I have a 2000 Ford F-150 Reg. Cab 4.2 V6 Manual Transmission and was wondering. I'm looking at exhaust systems thinking about going with a gibson side exit system. I dont like the flowmasters because you can here the exhaust loud in the cab. i was wondering are the Gibson exhaust like that? i Dont want to spend more then 400 on an exhaust system.
