daily driver 01 itr. intake= stock box with k&n drop in. headers= mugen, exhaust= stock or twinloop (hy/mug). want to go the hondata s100 route, i wont add anymore to the car other than bolt ons, so my question is i could save alot of money going with the stock exhaust and still get the car tuned with the s100 or i could shell out more $ for a twinloop exhaust. i'm just trying to get to 180whp and have it reliable. would this get me there?

cliffs: i/h/e with s100 hondata. whose done it and what'd you see hp wise.
