Just what the title says. Looking to put long tube headers and exhaust on my 4.3... It has no cats right now as well and I'm not sure if I should get them put back on.. As far as exhaust I'd like to get a nice low rumble sound out of it but I know there are limitations being that it is a v6.. Just looking to do a little upgrades that I can live with until I drop a 6.0 in it. Thoughts? Questions? Concerns?
 
Waste of money IMO. It will only gain you sound, not performance.
If you added headers and then got a tune to work together with them, along with an intake, then you would probably gain a minimal amount of horsepower. And I stress the word "minimal". I would just save that money towards a v8 swap, even if its only a 5.3
 
word no sense in dropping a few hundred on mods that won't transfer over to a V8 kinda a waste. If anything, do a cat back exhaust and focus on trans and drivetrain mods to support that 5.3 when you drop it in.

THIS. I had a 4.3 S10 in high school that had dual exhaust and it sounded like complete shit :laugh:

If you want more seat of the pants gains, regear to a lower (numerically higher) ratio. That will benefit you now and after a v8 swap.
