Can anyone get some pics? I would really love to see some. Glad to hear everyone likes them so far. Not as scary

Installed in the bay and where they hook up to cats would be cool. Like how low they hang. It says on there site legal for 99-01

It wont be for probably another month or two but when I do buy the Tri-y's and get them installed I will get some pics up of the whole process. I am looking into getting a dyno run done before and after the headers but I don't know how much of the HP increase will be from just the headers because I am going to get my 8.1marine injectors installed during the same time and will get the re-tune for them both at once.

Steve Bryant has these headers installed on his Yukon 2500XL 6.0L. Here is a link to his photos of the headers. Webshots Rides offers thousands of the best car wallpapers.

O man these things are nice. I take it Steve doesn't live in Cali cause I don't see any cats

I believe that Steve is still running catalytic converters. I think the 2500XL Yukon & 2500HD trucks are similar. The 2500HD trucks have the cats further back than shown in Steve's photos.
