What is the OUTSIDE diameter of the stock LSJ exhaust at the muffler on both ends of it?

bump

 

isnt it 21/4

 

I thought it was 2.5, 2.25 where it bends to go over the rear

 

someone needs to have one laying around

 

im pretty sure its 2.5

 

something like this..i dunno man sorry mines been gone for months

 

its 2.5

 

outside diameter of the pipe before and after the muffler

bump

 

everything is 2.5" besides the bend by the rear driver side tire,thats where it turns into 2.25 and into the muffler

 

so one end of the muffler is 2.25 and the other is 2.5

 

Its 2.5 (before bend over) > 2.25 (bend/over rear/bend again) > 2.5 (before muffler and out to the tip)

 

alright its raining sicklike or i would measure so thanks to all

 

No problem, kinda curious as to why you needed to know now after this thread

 

cooking something up and needed the figures

just to clairify is that the inside diameter of the piping or the outside

 

so now my question is,why are people paying 500+ bux for catback exhausts,when they can go to a shop and have that 2.25 piece changed into a 2.5 and save 400+ bux...thats what i did,plus looks stock and sound nice

 

The stock muffler is very restrictive as well .

 

would be interested to see a comparative dyno of that.
see if it stacks up to the 12whp gained by the gmpp

 

getting pipe bent up is the same as buying a cat back and is way cheaper

 

not really,ur just payin for the stainless steal exhaust system..its not like the cobalt can live 50yrs,even if it does,id still rather pay 50 bux for an catback non-stainless,than a 400bux cat back stainless with same or similiar hp gains
