So without going into how this happend, I am currently stuck with this: After the catless H-pipe One side has a short flow pipe and flowmaster 44 muffler. The other side cutts off at the H-pipe (flow pipe and muffler are no longer connected). With a limited understanding, I would think that this will cause unequal back pressure. I am currently about 3.5 hours from my garage, and was going to make the drive this weekend. Will this hurt my engine? It is loud as heck, and I fear getting pulled over if I were to just take the other side off. One look underneath and any cop could tell there are no cats.
