we are in the middle of changing our process to port basically the entire piece. previously we have ported the first 2-3 inches because most the gains you get are from taking away the steps, not smoothing out the entire inside of the pipes. but in the near future we'd like to step it up a notch and get the whole thing ported/polished for you guys for that added .000001 hp
imo, polishing the whole inside wont gain much more..but it does have a nice bling effect

neither. the coating we use can be self cured on the car, however when installing you have to be real careful not to scratch up the coating or else you are going to have problems. we are still doing it but for a reduced cost. in the next couple of weeks we will be moving into a shop so we will have the ability to cure the stuff before we send it out....then we should be game on again.
