Okay, that's out then... This is the original drivetrain from a '91 Blazer, but it's being dropped into a '92 Jeep Wrangler. I figured the stock y-pipe would be a good starting point for my exhaust work that I need to do.
Of course there's always the you pick em junk yards. I've seen a num
of factory y-pipe laying about. You want to be sure you get one
from a Jimmy or Blazer as they're 2.25" at each bank while the merge
pipe is for the cat and o2 sensor is 2.50". I believe the p/u truck
version is only 1.75" at the banks or smaller. Not sure on that though.
Edelbrock makes a aftermarket y-pipe for lowered rides that is 2.25
and 2.50. It is different than the y-pipe that comes with their TES
kit. It looks like it could work. It's made for the 4.3, 5.0 and 5.7
I think. The only drawback is it's for a full-size truck. Now I don't
know why it couldn't work on an S-Series ride. I don't know if the
y-junction is at a different angle. but since your converting to Jeep
it's all up in the air anyway..Link >
I like that Edelbrock piece, but I don't know if it would work with my application because of transfercase clearance. Most of the boneyards around here tend to throw the Y-pipes away, unless you go to a pick-n-pull which is probably the cheapest option. It's just one of those things that I'd rather have a all new exhaust all the way through, but can't find that Y-pipe hardly anywhere... I mean, if you had one that was rusted through and just needed to replace it, where would you go and get it from????
As far as I know it would. The diff between the 4.3 and a 5.0-5.7
are two cylinders. I don't think the engines are any wider, though
this may be wrong. If I had to get a y-pipe, I'd most likely get one
made. We have a number of custom muff shops out here in SoCal
who might take on the job of making a new one up..I do have another
idea, though it's more than likely half-a$$ed too..JBA makes a y-pipe
thats pretty interesting. Again it's made for the full size but it will fit
the 4.3 5.0 and 5.7 and has an pipe that you add to the crossover
to make it work..Let me see if I can find a pic of it..Well I found two.
the first one is for the 2wd, the second one is for the 4wd..I don't
see why, with a bit of modding, a person couldn't get these to
