Im running Belanger headers to magnaflow cat back wondering if taking my truck to the local shop and having them hack off the cats and install 3" pipe in its place is worth it? I will be going to the dyno to get a tune for some other bolt on stuff that I just purchased so it will be getting a tune soon after its done. Just saw some mixed reviews, even some people losing hp?! From what Ive read I need to get two O2 sensor simulators and then weld in another bung so i can get wideband?
