I am going to be getting a new exhaust but I can't figure out which way would be more benificial. I have a set of gibson headers of the truck now but I want to run a high flow cat because factory is so restrictive. the cat on there now is only about 10,000 miles old so it's not bad. I was thinking about runing it out to duals with flowmaster 44. Someone told me that I would get more power if I ran a high flow cat to the muffler and out a large single pipe. If so how big??? or does anyone have any better ideas???? im wide open

 

Which engine?

 

Polls still don't work on this forum. People will just need to post their choice.

 

i would say cherry bomb extreme muffler duels out , it would prob sound better since you have a cat and headers http://www.youtube.com/watch?v=yWFxJpk1boM

 

It has the 5.2

 

keep it single, reuse your factory pipe.

 

+1.

 

I'm running a 3" in/out Magnaflow high flow cat then into a single in dual out Flowmaster 40. I like this setup.

 

I'm curious. Been all over the Magnaflow cat site, and I can't find where it says "high flow cat." Is this just a misnomer, or is there such a thing as a high-flow cat?

 

I don't know that it technically says hi flow on it just that they flow better than stock so people call them hi flow cats. You can get them at Summit. They are just universal Magnaflow catalytic converters.
