i have the rv6 jpipe and pre cat and ive noticed a very loud rataling nosie when i drive any help? is this normal

 

awesome info.

were these just installed? are all the bolts torqued down properly? does the sound only happen at certain RPM's?

 

Brennan, I thought you were going turbo?
there is no need for PCD and Jpipe if you're going turbo.

 

ive had it in for 4 mons and it happens around 2rpm and if i let of the gas

 

i would love to go turbo but its AT so i havent really decided yet ive been looking for 6speed trans lately

 

this is an installation error.
the two pipes are rubbing against each other.

go back over the install; and this time when bolting down from the pre-cats...slide a piece of cardboard in between the two "J's".
completely bolt down the pipe and then remove card board when finished.
