Nah, with my little 5.3, im gonna stick with the 1 3/4". I think the 1 3/4" headers can support up to 650hp. I won't be pushing that.Correct but the only thing different would be if I got LT headers I would go 1 3/4" for the 5.3 and for the 6.0 I would go 1 7/8".I think for the time being I am going to go with #2. I know, Im sorry to disappoint all of you 4ers but I think I should use the complete potential of my 5.3 right now, plus its already in my truck so I wouldn't have to deal with a motor swap. Im just going to get my truck ready for a TVS. Full bolt ons, plus FI cam, AFM delete kit, 14 bolt (possibly), FI converter, and FLT transmission. That should take long enough and drain my bank account.
Also, don't forget, that if it bolts to the 5.3, it should bolt to the 6.0... So... TVS the 5.3 until you can get a 6.0![]()
Go 1 7/8" on the 5.3 as well... If your boosting... Your engine will thank you![]()
Got it done yet?
