I did a long search for hiflow cats but All I find is post about headers, mufflers cats delete. But nothing about hiflow cats.. I would like to keep using cats since is my daily driver and don't want all the strong fumes smell inside the truck, like my last one I had.. anyone can recommend a good set of hi-flow cats please

 

Texas Speed has some high flow cats. I have never used them but I know they have some lol

Edit: There is a user on here that is actually selling a set of them I think, check the classifieds

 

Thunderbolt metallic cats are the best bang for your buck that I have found in all my searching.

High flow
Metallic
Reasonably priced

 

I have a set of "high flow" cats on my truck, but they don't do much. When I was looking for replacement cat that actually works I ran across the old Vibrant GESI cats. They stopped making them but another company makes them. I will warn you, they are not cheap. It's what I'll be going with when I redo my exhaust after the engine swap.

Is the brand "thunderbolt metallic"
or just thunderbolt and they are metallic?
Reason I ask is because I found a few with the brand thunderbolt but not thunderbolt metallic

 

The brand is thunderbolt, you can find them on ebay. You want the metallic version.

I have them on my wife's C6 and I had them on my truck. They work very well.

 

I’ve had good luck with the magnaflow cats.

 

Back in the day I bought the biggest magnaflow i could get in a 3” dia. I think it was for some 6.2 truck. Good quality. That being said i have not run cats in over 5 years and im completely happy

 

How are the fumes smells inside the cab
Its my daily and I didn't want to have the stinky fumes. I didn't mind when I was younger and dressed up to go on a date all stinky lmao

 

Have the Magnaflow Y-Pipe and cats on mine. The pipe design alone is better than the original and the cats are not Chicom garbage.
