I ordered mine through Tbyrne because there was a 10% discount at that time. I just received an email from Tom at Tbyrne and he said that it should be shipping middle of next week. In prior emails with him, it was mentioned that the headers were not yet available from AS&M. I guess that must have meant that they were backordered??? At least Tom and the staff at Tbyrne have answered my emails and kept me up to date.

Now if anyone is coming over to Hawaii for a summer vacation and would like to help me install some headers... <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

From what I remember with my conversation with ASM, they are either 2.25" or 2.5", can't remember specifically. They are not 3" I know that for sure. I know some shops I have talked to like MTI said to cut off the collector and weld in a new 3" one, just cost money. I had custom headers made from Lapole with 3" collectors and it came with reducers to 2.75" for my 6.0L exhaust. Great quality and price, we will see how they work soon.
