can it be done without modification? i have a 6 litre and right now my truck is just sitting in the driveway open headers w/ no y-pipe. i ordered a pacesetter ORY yesterday to install and im wondering if its just gonna bolt up. txsilverado told me i'll need to modify..wtf should i do?

 

It should bolt right up. They are a pita to get on though.

 

Does your Corsa have the y before the inlet to the muffler? I believe so. If it does then you will either need to get a corsa intermediate pipe or get a custom y-pipe built.

 

so the ORY thats coming in is pointless?

 

Yes if you have the y part on the corsa. The pacesetter ORY is for 4.8/5.3 factory style exhaust.

 

im getting a little pissed off about this now. so i can use it, but i need to have a muffler shop fabricate a piece connecting it?

 

You could do it that way too. They would have make a piece to go from the muffler to the ORY.

 

if you are getting just a corsa muffler, place it where the stock muffer was and the rest will bolt right up to the ory.

 

dumps baby, dumbs like a truck truck truck.

 

^^ you are an idiot he is asking about how to attach the headers to his 6L corsa system not what to do after the muffler. Dave the cleanest way to do it is to get a corsa intermediate pipe for a 5.3 system but you can also get two pipes made up to connect to the y that corsa uses for the 6L system.
