i had the old stillen y-pipe then i sold that to get the new ceramic coated 1 from stillen.
the only reson i bought the new y-pipe and sold old one because i wanted the dam bee noise gone.
well stillen said that there should be no bzzz noise, they said it was my cat or my muffler.
so i did this i disconected the cat-back pipe from the cat to see if it was the cat-back exhaust is wasn't so then i disconected the y-pipe from the cat and it still maid that dam bzzz noise i want to know how i can stop the dam bzzz noise.
i was thinking of putting 2000 muffler on to stop noise would that work.
did any-body have that problem with there y-pipe?

 

Go to a speed shop and get some header wrap. You need to wrap the flexible section of th Y-pipe inorder to stop
the buzzing sound. Add some band clamps to either end of the header wrap to hold it in place.

 

Hey Dan.........could I use the stock bolts on the y-pipe u sold me? or do they have to be the ones that came w/ the y-pipe? Just windering cuz the instructions read that the y-pipe comes w/ it's own bolts
