Highflow Cat

[acelay]

Hello all, I was curious if anyone knew of any companies that sell highflow cats for the 6.4? Thanks

There are no high flow cats on the market that I'm aware of. But the better question is why keep the cat at all. Unless your keeping the very restrictive DPF as well , you'd still be illegal. There are plenty of cat/ dpf delete pipe out there, use one of them.

The cat would tone down the noise a bit.

I have a cat/dpf delete but would like to tone noise/ and possibly smoke down and not be such a dirty diesel

im coming from a 6.0 and just did dpf delete last night and this thing is still quiet. but i hear ya on the dirty diesels. i only drove the truck up the street to see if i had any exhaust leaks and it already covered my exhaust tip in soot.

the cat isn't overly restrictive. you can just put it back on

Have you stood behind it or near the exhaust exit at idle? It sounds like a jet plane! I am just trying to minimize the sound at idle..

if you don't like the turbo sound, replace the muffler with a packed style muffler. Or you can add a packed bullet muffler up front

you dont like the jet noise????? i love it, haha. have you ever heard a 6.0 with a 03 turbo. the 6.4 has nothing compared to the 6.0 whistle

I like it but it's too obvious that I have a deleted pipe!

I am most likely going to order the diesel cat below. I want to cut down on the smell, and hairdryer sound at idle. When I ordered the delete pipe they said it would not give off that non cat smell and there wouldn't be smoke! I do not want to be that dirty diesel around town!! I hope this cat will be a happy medium between the stock cat and no cat..
