High Flow Cats smell vs Straight Downpipes without Cats!!
Just did APR High Fkow Downpipes and curious to know,
Am I the only one bothered by the SMELL even while cruising at low speeds!! Granted the car is better overall and throttle is better but the smell!! Can’t imagine will be worse without cats!! Any experience ?!

I'm sure the stock double walled DPs will smell the same without the cats as the aftermarket catless DPs. I have the gutted stock DPs and there is a definite smell for me when I come to a stop and roll down my driver's side window. That is the only time it's objectionable for me though. If I'm moving at anything above 5 mph I don't notice a smell with the window down. No smell at any time through an open sunroof, stopped or moving.

Maybe you need to join the audi boards--- since you are talking about an S8 and asking for technical help.
