don't know what you mean by collector. Usually when I see people refer to collector it is the end of the extractors/headers where it all collects. The OEM DC2R Piping size is 2.25" (90% on this).

My 5zigen axle-back thats on sale is 2.38" (60.55mm) =]

Yer ive seen that page before.. Ive read in alot of places that the pipe is 2 1/4 but the collector size is 2 inch, which makes no sense... The one im intested in is the 3 bolt one inbetween the cat converter and the B pipe!! This is what ive found,, http://cgi.ebay.com.au/ws/eBayISAPI....=STRK:MEWAX:IT... Any idea's

AuDM ITR Cat (long 3-way) is 2 inches, B-pipe is 2.25 inch

JDM ITR Cat (short 2-way) is 2.5 inch, B-pipe is 2.25 inch

Hope this helps you.
