So I can get a pretty good deal on a set of TSP 1 7/8'' long tubes with cats from a local guy going back to stock. I know it's recommended to go 2'' on a blown car but is it really needed? I'm not looking to squeeze every bit of HP out of the car. Also, this is the catted set up....how do those cats handle the extra stress of a supercharged engine? I'd rather run no cats but from what I've read the NPP gets crazy raspy with no cats.

What do you guys think? All opinions welcome. Thanks!

For what it's worth I'm getting cat codes on the stockers right now so I figured I'd just go long tubes...however I'm also not opposed to just doing cat delete pipes and then I'll figure out if the NPP is to raspy.
