Anybody have this issue. Excessive exhaust fumes leaves me smelling like I sat in front of the xhaust pipe. I know this is more of a race car than a DD. but it is a DD. I am presently getting a new tune ( SD), among other things we are trying to safely lean out what may be too rich. If this doesn't work I was considering adding a cat in my I pipe and put a cutout just before it. Mabe a boost activated cutout.
Any have experience with this, is it possible & can you recommend a cat.
Or a better solution ?
FYI: I do not have an exhaust leak, and it is not blow by. It is exhaust mostly at idle at a light etc..

 

Cats do not do anything for exhaust fumes.

 

boost activated cutouts typically do not react fast enough. i would recommend a normal electric cutout with cabin switch for when you want "go mode"
