I'm about to get some Kook's long tubes installed on my Mach 1 and I was curious to see if most people use the extensions that Kook's provide or is it better to use longer O2's instead? Is it the front O2's that need the extensions versus the rears? I read somewhere that people were using F-150 O2's in the front to get around using extensions. I just wanted to confirm before I bought something. I searched a bunch of O2 threads but most of them were about burning out O2's, E85 and angled use and some were about the 6.2L Raptor O2's for the fronts.
