High flow cats???

[Magnum375 Jr]

I don't know if anyone knows this but there are universal high flow cats that should fit the V6's. I dont think the gain would be as big as they are with the RT's and SRT's, but magnaflow makes them. I saw them today in A&A truck parts.

How big of a difference would the make when coupled with headers?

Alot because backpressure would be eliminated, allowing more air to get out faster.

That's good to know.

I am currently running straight pipes on my Charger SXT, and I'm anxiously awaiting the JBA headers. Now, I guess I'll look into high flow cats.

Yeah but too much back pressure can be a bad thing as well.

I asked the question about the need for high flow cats on ChargerForums.com, and here is the response:

According to JBA our cars already have 3" mids pipes (were the cats are installed) so changing the piping and cats are not worth it.

Note: JBA is currently working on a set of headers for the 3.5L V6 (not sure if they will fit the 2.7L). The test car is currently up for final fitting and dyno test.
