okay, this may sound like a stupid question, but whatever: does a cat-back include the cat, or is it just past the cat all the way back? and if it doesn't, what are some brands of high flow cats that you guys recommend? maybe even some websites, too.

 

No it doesn't include the cat. It's from the cat and back.
The two best sites are Howell & Modern Performance. Howell is cool and they are also a sponsor. Check them out first and then Modern performance is a good place too. There are plenty out there u just have to look.
