It will be dumped right after the cat and before the muffler. What if I put my turndown tip on it? Would that help?
I currently have turndowns on my wk 05 with no cats.. I've been in bumper to bumper traffic with my windows down and haven't had any fumes come in. Given they are right before the axle as you can see in the picture.
Only problem i have with fumes is when im sitting somewhere and throw it into reverse and back up then i smell it with the Windows down. This also happened when i had a normal exhaust setup with the tube coming out the rear.
Im pretty sure since your keeping your cats then you will hardly notice it but might want to through in a muffler and put the turndowns after that. But that is easily doable after the fact if you want to change it
