Are you running dual straight pipe, X or H? I have a 5.3 cammed dual straight pipe with 20 year old flowmaster 40s. I like the old school 40 sound but I don’t know whether to keep dual straight pipe, X or H when I replace the mufflers.
@@htowngizmo9799 No straight pipe, no X, no H. It’s just cat less 2.5 to two flowmaster 40s dumped before the axle. They’re ran right next to each other as well. All this exhaust is off the truck though as it’s torn apart getting a turbo.
Not at all, this is an unknown mileage, junkyard 4L80e that I threw a sonnax line to lube valve and an HD2 Shift Kit without the pump mod in. I wired it up with a Holley for a 4l80 but before that, I just had a small harness extension for the 4L80 to run on the stock computer which I just segment swapped from and HD van to get it to run. The swap crossmember was a couple hundred bucks but the expensive part is the $1050 converter in it which was my choice to buy, it’s not necessary to go that big and expensive.
@ArkArmy90 you could keep a stock stall, but it wouldn’t bolt up to your 4.8 flex plate. I also wouldn’t put a stock converter behind a stock 4.8/5.3 in a 4L80, it’ll drag badly, but you could do it.
Do you have the cats? Depending on this type of exhaust but I’m currently catless.
Heck no, those cats are long gone, buddy.

Stock manifolds
@@trevorober2384 nope, BBK short tubes.
Was the 4l80 swap expensive ?

@@ReformedBluegrasser wow so could I do this with the stock stall if I'm working my way up to a L92 swap I have a 4.8 now ?
