I have a few questions
first off, is High Flow a brand name, or just a description of the cat?

second, I have a borla cat back exhaust on my v6 bird, how much of a difference will the sound be with a high flow cat, and how much performance gain if any?

third, how much do they usually cost, and where can I get one?

thanks guys

 

High-flow isn't a name, it's just a cat. that has higher flow . This website has high-flow cats. www.thunderracing.com

 

I saw test flows on high flow cats and random technology came out on top followed by car sound. I only remember those two.

 

going the budget route CATCO has the cheaper route and i have heard good things.

I think they are about $120 cheaper then reandom techs cats.

Deeper and louder. My dynomax sounds like the flows I had at idle due to the highflow cat.
