Exhaust Turndown

[nichnapa]

I lost the exhaust down spout on my 2008 32' Born Free with a 6.6 Duramax engine. I am looking for a factory replacement. I think the original was an air gap with a 3.5" I.D.. Not sure of the O.D. but it was very large.
Thank you.

Since it is a Chevrolet chassis part should be able to order a replacement from a Chevrolet truck dealer.
