I notice a lot of guys post from farther south but has anyone had their stock exhaust rust through/off yet? The bottom of my truck - despite a 2x's per month car wash in the winter- looks like s__t. This last week I lost the tailpipe from the muffler on back because the flanges rusted through - not the pipe but the flange - I was saving for a Banks set-up but I wanted to do it AFTER Christmas. Guess I thought it would hold out longer than 4 years... But maybe that's just Minnesota.
