My 2000 S showed a definate torque increase from 1000rpm to redline with Dansk sport cats & 2.5L Top speed f1 headers & stock muffler. Much easier to start off from stopped & zero resonance noise. Now that the 3.6 is broken in it needs bigger pipes & collectors so I am installing ceramic coated secondary bypass pipes & 3.2 headers with stock muffler. Proper pipe size has to be matched to engine displacement for low rpm torque gains & bigger is not always better.
The Dansk 200 cell sport cats & Top speed headers are for sale $800.
pics are to big for 986forum so pm me if interested in buying & I can email them.
