Is a smaller exhaust pipe an issue?

[Tototex]

I have an M51A2.

There is a big hole in my lower exhaust pipe. I took it down to the muffler shop and they want to replace my whole 3.5" pipe with 3" pipe since that is the biggest they can bend.

I have two issue with this.

1.) Can this impact performance in any way or nothing to worry about?

2.) It is kind of disappointing as I want to keep her as original as I can.

They say they can order some 3.5" pipe and weld it together for me, but they are pretty reluctant about wanting to do it.

Thanks in advance.

Did you have Memphis Equipment among others quote a factory part?

1) increased back pressure will rob power, worsen fuel efficiency, and degrade throttle response.

2) It'll bug you forever if it is already disappointin to even contemplate.

If they're reluctant, find someplace that isn't. JMHO

Go to a big truck exhaust shop. They can bend up to 4inch sometimes 5inch pipe with no issues. Just depends on their machine.

Memphis doesn't carry my pipe.


Whites Owl does.

$110.00, $155.00 after shipping for the pipe.


Its not much.


The only reason this shop has my muffler is because they owe me some labor.


I work next to a Peterbuilt. Maybe I should see what they want to bend the pipe. I imagine it will be more than $155 though.

I'll probably keep my foot down and just have them weld my pipe back together. Can't beat free and downsizing to 3" will bother me forever. Thanks for that comment because it is true!

Just to follow up. I ended up ordering the pipe from white owl. My current pipe was to weak to weld back together.

Most guys don't bend the 3.5" and larger, they usually buy the premade ells and weld them together.
