Exhaust - Cat Back = what?

[Bird325]

I feel like a real noob asking, but I haven't been able to get a definitive answer. I already have Ballenger headers and RT high flow cats, now I'm looking to upgrade the last part with 3" pipes and a good sound. When Corsa or Borla says 'Cat Back', is that including the CATS or not? If COULD mean 'from the CATS back' which would include cats or 'from behind the cats'. I'm sure someone has purchased both systems ... what does it include?

I believe it means from behind the CATS and going back.

Yes, not including cats at least everyone I've bought

As noted above "Cat Back" means beyond the converters. One thing that you should note, the Corsa is available with a true 3" system (that includes the piping which connects to the cats). More than likely your sysytem will require the 2.5" connection system that a stock Viper would use. The later system is all 3" except for the connection pipe. Since your system is not stock, you should at least verify your pipe size on the back of the cats.
