i just put on a used y pipe a couple days ago and now there is a rattling type sound whenever i give it some gas. what type of sound does the "bee's in a can" make??? new nissan gaskets were used as well.

Heat shield material rattling against it?

i dunno for sure if i have the same thing, but i've noticed that when i go by a car, and i'm on the gas, there is a slight hissing/buzzing noise from around the y-pipe. I had it checked at my local Meinike (sp?), and they said there are no leaks.

Does anyone know of a place i can get some header wrap?? I think that may solve my problem, but i can't seem to find any anywhere.

I had that sound on my warpspeed for the first 2 days after it was installed. Only at WOT though. Now it doesn't happen.

 

i have no more heat shields because i had to take it off a while ago.
the unit i installed was used, but i have no idea anymore.
i have driven it for about 4 days now and still no difference..sound is still there.

wierd stuff..

wow, that stuff is actually kinda exspensive. Where did you guys start wrapping your exhaust? I think my noise is coming from the flex, but the shop i went to about it said they saw nothing wrong with it......

anyway, i guess this is going to be a time consuming install...but if it gets rid of that hiss, then i guess i don't mind as much.

 

Yeah that sucks dude. I just bought a new warpspeed y pipe and it had the same rattle at wot but only for two days as well???

 

thats strange, i guess there's a certain breakin period for them, do you guys have some clearance issues with the underside of your car?? I have like a 1/4" gap between my y-pipe and the little channel before it goes into my cat...
