So I'm going to clamp on a new muffler to replace my POS cherry bomb. I'm finding contradictory information about the stock exhaust side. I'm seeing 2", 2.5", 2 1/8", 2 1/4".

What's the stock exhaust size from the cat back?

Elton

its pretty small like 1-7/8'' or somtehing

MaK92-4RnR

yeah its like 1-7/8". I think 3vze's are 2 - 1/8" aren't they?

DupermanDave

I just want to find out for certain before I saw off the cherry bomb and not have the proper piping to fit everything in place.

MaK92-4RnR

just put 2.25 piping on it.

DupermanDave

2.25" isnt going to fit well if the other end is like 1.5". Unless the mating pipe is flexible.

Elton

yea id run 2.25 from the cat back

Actually 1-5/8" ID and about 1-3/4" OD is what was on my '85.

Elton

ahh well i was close enough

Anyway you look at it...it's just too small.

So I'm looking for a pipe about 1.75" for a stock system to mate with the muffler?
