6.7L Cummins Forum

I've 08 6.7 3500 and when changing over to winters I noticed a large hole at the first elbow after the mufler. It doesn't look like an easy change as the tailpipe is male. This could get old fast,so I'm looking for a stainless. Since this truck is used on long trips, noise or more to the point lack of, is important.The parts store had 4" or 5' stainless from the cat back. Any brand or suggestions?

There are so many different products when it comes to exhaust. I would suggest doing some reserach on sellers of such items and read reviews of the product and see which goes best with what you are looking for.

I have been using Xtreme Diesel Performance - XDP Diesel Power Performance Parts for most of my research and ideas. I ordered my Banks Cold Air Intake with super Scoop from them.

But they have a wide selection of stuff. There are several other sights that I Google from time to time just for price comparison purposes.

You shouldnt have any problems finding a 4in SS system to your liking.


Good luck and hope this was of some help.
