  • they really dont sound loud on the v6's

    how loud are they in person?

  • Well it wouldn't be as loud if I kept the stock piping on there... since this video the jeep's had a few thousand miles put on it, and it's really been broken in.. Put it this way, I pulled up next to a modded out mustang the other week, and my truck drowned it out.. haha, you couldn't even hear the mustang after I hit the gas.

  • is that a v8 or v6

  • 4.0L Inline 6.

  • That tapping you first get at startup, I've got that too. I haven't been able to figure out what it is.

  • The tapping noise went away.. I've since done ALOT more work to the jeep, including: Intake, Plugs, T.B spacer, Synthetic oil, and soon to have a hypertech programmer.. Not too sure what It was, might have just been wear on the internals.. since I changed over to synthetic, the truck runs like it's brand new

  • The tapping is because of hidraulic valve lifter failure...typical on any 4.0L jeep engine. Try using the "restore" additive....it has worked for me in all 4.0L jeeps I've owned.

  • @WoWKazo ok so its not my jeep. but i have an 01 limited. arent all the limited all 4.7? in the 99-06?

  • how much was it for the new pipe?

  • I'm gunna sugest a black westin brush gaurd for your jeep. It looks sick on mine and would look nice on yours too. Also gotta get a system inside man.

  • not bad. check out my super 44 on my jeep wj and tell me what you think
