I have a 98 z28, just recently broke a torque arm and when that happened my exhaust seperated on driver side right behind the cat, it just pulled right off the studs. What im wanting to do is take the cats off and get a offroad y pipe. Will the y pipe bolt up to the stock manifold and what do i do about the o2 sensors. Also what y pipe would work best for what im trying to do. Any info would be appriciated thanks!

mufflex-performance.com offers cat-bypass piping that will bolt right up to your factory manifolds and factory y-pipe. You could replace the y-pipe w/ a Doug's y-pipe, but you will still need the cat bypass from Mufflex. For the money, just spend a little more and put some headers on it and a off-road Y-pipe (ORY) like a pacesetter kit.
