cleaning out stuff and have 2 sets of Stelling headers and 2 sets of air switched mufflers. was told they were from a stagger boat and the mufflers seem to confirm that. the headers were pressure tested years ago and have been sitting in storage for 8 or 10 years now. they are very clean and the inside of them look like they were barely run. the mufflers are not the cleanest and could really use some cleaning and the air cylinders need new seal but they move free so should be good to go after fixing the seals. the headers are right side black and left side orange. not sure why but assuming it is because they were on a stagger boat. what you see is what I have, no distribution hoses or pumps for the mufflers. asking $5500 for both sets of headers and $500 for the mufflers plus any shipping.






feel free to ask any questions.

Does it look like they would only work on a staggered install? Really can't tell from the pics of these are the same or not...

not sure, I wish someone could come up with a chart of what the color codes mean on these things. I am going to mount them to an engine in the next day or so and get some pics of how they sit on the engine and maybe that will help.

here are pics of the headers on an engine. the right side rolls in farther than the right side, there is about 1.5 to 1.75 difference. based on this I assume they really are for a staggered setup.

Can you tell me the ID of the primaries?
They look like they may work for me

look to measure at 2". that is at the head flange. OD of the collector is 3.75". let me know if you have any other questions.
thanks

Ok Thanks, I'm going to be at the boat next week, I'll check measurements and get back to you
