I have a borla cat back and was thinking of upgrading my stock cat converter. It passes emission perfectly so i am not desperate. Will a hi-flow cat make any real performance increase over stock? I was looking at the magnaflow for $70ish on ebay. Thanks

 

the term HI flow is somewhat a marketing term , its used for every honeycomb style cat, there are some spiral wound cats made now that do flow a little more, but a reg stock style replacement cat is the same as most marketed "hi flow " cats, so don't fall for the name, honeycomb style cats do flow way better than the older pellet style cats from the early years, but you can't buy those anymore so just get the cheapest one rockauto.com has and you are fine.

 

Go magnaflow, good quality and they are cheap. I like mine

 

I'd still like to have my exahust done at Carline. I'd like to hear yours if I ever see you around town.
