does the JBA H-Pipe use the stock cats? or does it come with a set of new cats?

I'm thinking of making a real mean sounding V6, so I figure I'll throw a JBA H-Pipe (for the deep muscle sound) and the JBA Shorty Headers (for the rumble up front), and use my SLP Loudmouths (name says it all).

After I do those mods, I may have line lock put in, and get t-lok w/ 3.73 gears, and then one or two body mods, and leave the 6 banger alone till I get the SGT.

 

stockcats... the factory pipes get cut after the cats.

 

thanks

 

It does sound pretty good without the headers, the headers will def make it louder. I don't know about using loudmouth's though.
