Just recently since the weather has gotton colder here I've noticed my Mustang makes a real tinnie sound around 1400 and 1900 rpm's in any gear. I also just put on a MAC ProChamber, could that be the tinniness I'm hearing? It's not a big deal, I'm just curious.
my stangs louder in the cold weather.... no big deal here.... no tin though.. I have the catted prochamber, but I just put it on today so I dont know when IT sounds different yet.
if you dodnt put a gasket on the drivers side where the prochamber connects to the headers most likely its a exhaust leak.
just get the donut gasket and you will be fine
I had it professionally installed, so I don't know if they put a gasket there or not. I don't have the necessary means of jacking the car up to get at it. I guess I could find a way to check it out though.
