Wow, my head is swelling from all this new information... Great thread guys (even if it isn't following the first post at all )

 

Venturi's!!!!!

 

Hey thats cool with me! lol I was planning on running a 2.25" pipe because that is what the mufflers are and I thought it sounded reasonable. I know I dont want anything above 2.5". I honestly couldnt tell you what is on it right now. I am pretty sure it is stock up to the muffler then it splits into 2, 2.25" pipes.

 

Great info here!!!!!!!!!!!!! Having worked extensively with a pretty good sized turbo charger, the size of exhaust does has a pretty big effect on how a certain vehicle performs. I am still trying to figure out the 5.3 liter V8 so I'm not so savy as to make recommendations. Hope everything works out good with the project and you don't have to unload cash on an exhaust that doesn't work for you.

 

Thanks yankee!!!
