Default What grade of stainless
Anybody know what grade of stainless steel they used for the exhaust on the nnbs trucks? Specifically the 3.5" exhaust that comes on the trucks with 6.2.

I think it is 406 stainless. 304 Stainless is polishable which is what the Corsa, Borla, and other aftermarket manufacturers use.

Not looking to polish. Buddy of mine is going to weld in my cutout and asked me what grade stainless the exhaust is.

The front part of the exhaust is 409 stainless and the tail pipe is just aluminized mild steel. It can be welded with mild steel wire and a regular mix of argon and CO2.

I'm gonna put the cutout right after the bolted connection (where the y pipe bolts to the rest of the catback) and before the muffler. Are you saying this part is aluminized steel?
