85 Mustang Exhuast Conversion to 87+

[Rains]

does an O/R H Pipe directly bolt up to the stock 85 5.0 Headers?

you'll need a dual hump crossmember from an 87+ car... other than that it's a direct bolt on..... of course you'll need a new catback as well

the stock h-pipe?

You don't want to hook them up the 85 headers due to the heat riser on the 85 headers. I would "at least" get some 86-up stockers for ~$20.

86 GT/LX =87-93 LX exhaust stuff.

nice job, i forgot to catch that one

The 1985 header has a 2-1/2" outlet where the newer headers are 2-1/4".

with the different size outlets-will that create a leak? Oh well, I suppose i should spend the extra cash and get some stock 87+ headers too

(Note: Stop being a cheap Mofo )

It already has the crossmember with the 2 openings for an aftermarker H, and the EGR tube also looks to have the classic, hose + 2 clamps attatched, so this pony (the 85) has had some exhust work done in the past....
