As I am looking at putting LT headers on my 2000 5.3 I am also looking to delete the CAT so it is just the headers into the Y pipe then the Cat back system I already have! Any thoughts on the Pros and Cons of this?? I live in MI so we dont have smog inspections by the way ;-)

 

enhaced smell of gas and noise...those are pro's and con's depending on your like...for me...PRO's :jest

 

Ya I dont mind the smell at all, hell that is how it is suppose to smell!! How much extra noise are you getting? Any Raspyness? I run a stock setup with a flowmaster cat back currently (Super 40). I am going with a Doug Thorley LT Headers and Cat Back....hopeing they will balance out.

 

my truck is way louder than most here would care to have. no rasp, it's too loud for rasp someone else will have to answer those quesitons. it will be quite a bit more noise i can assure you

 

Don't use a flowmaster for sure, the drone will drive you nuts from 55-65 with no cats

 

Well anyone reading this that has some video clips of a 5.3 with Headers, Cat Delete and exhaust please hook me up...Thanks!!!!

 

Thanks!! I was looking at the Doug Thorley System, they say it is a deeper but quieter sound like the Magnaflows.

 

Mine is quite a bit louder without cats and Raspy too. Terrible drone at highway speeds around 2000 rpm. American Racing headers, 3" duals into 3" dual inlet/outlet Magnaflow with dual 3" tailpipes.
