I was wondering what the Stock 5.3 Exhaust Diameter was on my truck..

I want to buy an electric Cutout but dont remember what the size I ordered was?????

Does anyone know.....

 

I was thinking 2 1/2

 

yep 2.5

I just hacked mine up, that piece under the pan looks like
its been run over a few times..lol

 

Ha... I had so much welded into my exhuast...

Two peices of pipe for when the cats were removed.....Duals from where the muffler was..

Then I had my muffler removed so theres another piece in there....

It looks like a 2nd graded welded in my exhaust......

 

Oh and thanks for replying.

 

But it works

 

The stock pipe is 2.75" not 2.50

 

Stock exhaust pipe is 2.75"!!

thats the first Ive heard of that

I just had 2.5" flanges welded on my togs

 

Stock exhaust after the "Y" is 2.75", before is 2.5". You still need the 2.5" cutouts. Any muffler shop can expand them to fit.
