Noticed a slow uptick in the amount of exhaust smell I'm getting the cab. It's become a daily burden. Stop light idle some cruising speeds. Windows down, or up and the air on it doesn't matter. Checked the upper and lower connection on my doe pipe and went so far as checking the flange that keeps them on and there is no sign of black or any leak. Where could this be coming from and why can't I seem to locate it.


Maybe time for a delete haha

Downpipe needs replacing or realignment/clamp needs tightening. This is mostly noticeable during regens.

Haha. You delete the smell will much more noticeable.

Well I was thinking the down pipe but it's not even 6 months old and the flanges are good. No exhaust mark on it for a leak.

Problem wasn't the cow pipe nor was it any other pipes. It was an over spray with the DEF in the DPF and emission issues. Hence the delete. Should help
