The car I bought used is an L99. The huge resonator has been removed. They added the exhaust that has 4 tips and it has the vacuum cutouts in the back but there is no vacuum hoses attached. It looks like the flappers are open all the time. it sounds pretty good. I noticed there is no "H" pipe. Is it needed and would it change the sound/ performance much?
