pop sound?
hey on my fifth gen lude (i have a stock exhaust) after its warm when it turn it off and its sitting for a little bit i can hear a strange noise from the muffler almost like a pop or something, is this normal or not and has anyone else noticed it if it is? please let me know, thanks....
Totally normal - it's the catalytic converter cooling down. That thing gets RED hot (hence the heat shields), and when metal contracts after being heated up it pops like that. It could also be some other part of the exhaust system - my exhaust manifold would do that on my old Volvo 740 turbo... it would glow cherry red, and pop --really-- loudly as it cooled. So don't worry at all.
