Agreed Anthony, there's no doubt they give a great sound, and you definitely will see some small gains especially in low end tq. But just for me personally, the gains are not worth all the troubles, it's really up to personal preference. I love LTs, have had them on all but 2 of my cars, preach their benefits all day long and would much rather have them then shorties (damn sure not worth anything, all those do are make plug changes harder), but in this instance I'll spend the money elsewhere next time, it's not worth the hassle. Plus the factory manifolds on these trucks aren't really all that bad, they won't really hinder the truck till you're making serious power.
How long have you had yours on there Anthony?
