  • Damn that sounds mean. What is the exhaust setup

  • @g1andrhone Seafoam is an additive that you can buy in a can at walmart and other auto part places that cleans carbon and other crap out of the engine. The smoke is the seafoam doing its job. (it also makes it a little harder to start because i believe it is added to the fuel.)

  • what the hell does seafoaming it mean? and why would you do it on purpose? doesnt it like get the water out the gas or am i thinking of something else

  • What kind of exhuast setup do you have? I've got an '01 and sounds nothing like that. Or that loud even.
