i have had megan res test pipes on my 04 now for about 5 days and i notice a rattle coming from the inside of the test pipe? I know its not rasp because i got under the car and had my dad press on the gas and it is coming directly from inside the test pipe...any ideas?

 

perhaps the resonator is broken?

 

A rattle snake sound?..

That's a different kind of rasp but its rasp.

 

have you checked to see if the TP is hitting any existing structure? Also, re-check your bolts. Don't tighten one up all the way then the next. Instead, tighten them progressively until each is nice and snug.

 

is it a hissing noise?

 

That noise is the stock ypipe if you still have it on. Having an aftermarket y will solve that problem.

 

There's a nice little thread right beneath this one (for now at least) that may cure your problems .

thanks for all of your help. i have a borla exhaust with it. It does kind of sound like a rattle snake but i will make sure everything is tightened correctly again.

 

wrong thread...
