High flow cat with powerpack?
Have a 2004 wrangler and personally installed the ram-air and monster exhaust by gale banks. I have the torque tubes ready to be installed, I have heard that it is alot better to use a high flow catalytic converter with the free flowing exhaust. I am about to put it in the shop to get the headers installed and they sell high flow cats at the specialty automotive shop (they build racing hot rods etc, one of the only shops in Lafayette LA that will touch headers) for 200 bucks. On the Banks site, it says the dyno runs etc were with stock catalytic converters. I am wondering if this is a good decision/improvement?
I figured while they have the headers off now would be the time to change the cat if it will really help out, it makes sense since everything is free flowing and a factory cat might be restricting? PS my emisson laws in LA are very loose so emission test etc don't really matter
