Hey guys, Currently I have stainless shorty headers on my '11 silver ado 5.3L and I want to go to a long tube before I do the blackbear tune this summer….do you guys have any advice? The shorty's just aren't right for my application; you really feel the power during high RPM's and some pull from the midrange but that's about it -- I'm looking for a long tube to assist me in the low end while towing, etc. So with that said..what brand would you recommend? I know it's tough to find a header that doesn't leak but obviously, thats the preference. These Gibsons have leaked from day one, even with some gasket modifications…they just weren't a good fit. I don't really care about price so much as I want something that fits, will hold up, and obviously, perform. Have read about kooks, pacesetter, dynatech, and beyond and do not know which way to go. Thanks!!
