Does everyone with long tubes and race cats have a smelly exhaust? Its the one thing I don't like about my car. I'm debating about switching to shorties and the stock cats.

I know people with that same problem with stock cats. You might relocate them farther back in the system.

Not at all...

Which cats do you have? Maybe mine are shot.

MBH high flow cats. The system only has a couple hundred miles on it though. Regardless, I wouldn't expect any smell...guess we'll see. Don't know if anyone else has your issue...it wouldn't be pleasant for me either.

I got ARH LTH with cats and I'm high everyday, really bad during cold start. I swear if I light a match I will blow up

well i only have secondary cats on my mbh headers system. Def smell at startup, but afterward, not really noticeable.
