Installed LTs/backfire
I just finished installing longtubes and i ran them open headers for about an hr. I noticed a huge decrease in low end tq, as well as backfiring when WOT? Are these problems common?

How far are the O2's from the opening of the collector? Most run a small extnsion either a turn down or something so the fresh air wont make it back up the collector. If the air gets up there The PCM will read lean and like others have said the PCM will be making the fuel mix way to rich.
