I've got 4085's (1 7/8) on my 225's and there's about 3-5mm gap between the steering box....in an XD. I'd like that one culprit pipe cut and recessed in about 10mm.
I think the 4095's are the 2" off the shelf. Any extractors with a
4V flange should fit the 3V raised exhaust port.
Got 436rwhp on his Dyno.....couldn't fit the
AFR probe up my exhaust dumpers though ;) ..........so still need to tweek the carby.
