what is the stock exhaust tubing diameter on a 2000 5.3??

looking to just put in a muffler or cutout....should i go with stock size inlets/outlets, or just have an exhaust shop fab a 3" In/Out into my exhaust??

also what muffler would some of you suggest...I have looked into Hooker Aerochambler, Dynomax Super Turbo, FlowMaster 40 Series, or just a cutout.

Thanks

Before the Y it's 2.5", after is 2.75" from what I understand.

Keep that stock 2.75" pipe to the muffler, it will flow better than a crush bent 3" pipe.

Well with those you suggested muff-wise you have a vast differences in sound...what are you wanting it to do?

 

hitman mine is 3 inches after the y pipe. it is 2.5 before. I am atleast pretty sure. I did the 3inch in and out 1 chamber cheap and a nice sound.

 

looking for a deep mellow tone, but not obnoxiously loud....not like these rednecks w/ trucks that make u want to wish to be deaf...flow/hp gain isnt much of an issue....when i want the truck to go fast ill just spray it

anyone else wanna chime in w/ their opinion on the size?? i would like to keep the inlet/outlet same size, so the muffler shop doesnt have to expand anything.

 

Mine was factory dual 2 7/8" also, I kept my stock tubing and just had them expand my 2.5" Dynomax Bullets to fit the pipes

 

just had exhaust put on my truck and the shop told me it had 3in all the way before they worked on it.

 

so i guess easiest thing to do is just buy a muffler and tell a shop "Put this...on there!"
probably gonna end up going with the hooker areochambler 2.5" In./Out.

 

bud go 3 inch in and out. no reason to go down in size. same price usually. also let me know how the aerochamber sounds.

 

i would like to go with the 3", but still havent gotten a solid answer to the stock piping being 3". I work for advance auto parts, and i can get the 2.5" In/out for around $60.....the 2.5" is actually in our inventory and is not a special order...for some weird reason the 3" would be special order w/ shipping charges applied ????

if i can get a solid answer that it IS 3".....i will go that route....not gonna do this for a while anyways.

ANOTHER ? - should i run a turndown before or after the axle???
