for $500 you can get the complete cat forward from a dealer installed.did it at a dealer had mine done when the passenger went out and caused a fuel pump burn out.
the muffler shop that i go to for work says the cats on the nbs are of equal quality to a highflow. the bricks are better made than the obs.


btw the dealer said the life of the stock cats is about 80k miles.
