7.3 muffler delete pipe

[dieseldan2005]

Anyone use flexpipe for a muffler delete on a 7.3? I am just wondering how long of a piece you need? Also does Napa carry that stuff or do i need to look at an exhaust shop? I know 3.5" diesel exhaust is hard to find.

I did it. It was a long time ago, but IIRC it was a 2' piece

I got mine atmy local International dealer. They had it in stock

Awsome, thanks Chris! Its a lot cheaper than a whole exhaust kit right now.

What diameter do i need? 3.5 ID/OD or bigger?

It is 3.5 but I don't remember if it is id or od.

You can always go with a Walker BTM muffler from Rockauto.com for $46 plus shipping. I'm happy with mine.

I just went outside and measured mine. It is still in my scrap pile It is 3.5" I.D. Here is a pic of what it looked like when I did mine
A Walker BTM won't work in place of a stock muffler

I am having a hard time finding flex pipe in 3.5 up here. Thanks for the pic chris.
