thats not a bad loss to be legal and not have to change when emissions come around

cats take away sound and performance

if u drive the same car with cats and then without you will FEEL and hear the difference

I read an article a while ago that said the difference between high flow cats and no cats its like splitting hairs, it's not much of a difference at all. However i do not have any personal experience with that. The catted pipes are a lot more expensive. Stock cats vs no cats however is a different story...

no cats = much louder.

HYE

i have a bbk off road x pipe
im thinking about putting cats on because it smells bad
is it just me or does everyone smell this and is okay with it
at first it was okay but after a while it sucked i like the sound and the performance i felt it when i got it.
