T409 SS duals

[mrplowjr73]

Does anyone make a set of of 304 SS duals?

I asked MBRP and they said that 409 will likely be the only material used on the cool duals on the 6.7...

REALLY?!?!? WHY?!?! theyre available for most other applications.

What does it matter? It could be aluminized and still out last your truck.

I had the Borla on my Toy for a decade. The hangers rusted, but not the pipes. They just turned grey. Borla warrantied it anyway, but it happened just as I was switching to a larger diameter pipe so I never ran the replacements. This was a decade in Upsalt New York.

Now running a Gibson setup on the Toy (my truck was the prototype) and it's also grey and a decade old.

So whatever Borla and Gibson are using works great.


Aluminized sux. If I still lived in a salt state I wouldn't touch the stuff. Actually, I wouldn't touch it now either.

I ran aluminized for over a decade with no issues. Even drove the truck in the ocean (I wasn't very smart as a teenager LOL) and none of the hangers rusted or pipe rusted. I guess I could see it if you lived in a salt state but even still to me the cost isnt worth it. And honestly, as long as my exhaust doesn't leak or sag, I could care less what it looks like after 10yrs. Now the exhaust tip I agree needs to be a high quality stainless cause it's in the direct path of anything getting thrown off of the tires and it takes the biggest beating.

I'm not sure it really matters why I want it I was just asking if anyone made one... anyway for those who must know I live in NY theres salt on the road 6 months out of the year, slush gets kicked up and freezes under there then melts and it stays wet all winter long with HIGHLY salinized water.

I want the polished look to last. I've had 409 before and it looked great for a year or two, but as was said it turns gray and pits then eventually rusts.

304 looks way better from the start. a shiny tip with a rusty discolored exhaust looks terrible IMO
