charlie to answer your question truthfully i didn't measure however i was wondering the same thing hence, i ordered them(naturally in my glee i forgot to measure) but they did look quite large il measure the O.D and try and figure out what would be close though for you(not accurate but its worth a shot) and SD56 i used a set of headman turbo mufflers. i love the sound and i was never happier with an exhaust instal/ set up!

The difference will be 1/8" which is a lot. If you use an adjustable wrench (crescent wrench) and adjust it so it fits a straight portion of the pipe, to avoid any distortion by the bend, and then measure the distance between the flats on the wrench - that'll be close enough.

So, I was ready to pull a trigger on a set, and I verified the tube size with Speedway. They are, in fact, Patriot Exhaust headers and have 1 1/2" primaries not 1 5/8". I'm not going to try them.

Charlie: Have you considered going with Rams Horns?

No. I want to try some bigger headers but I already have 1 1/2" tube headers.
