IMHO, either you should go for a full system...or stay on OEM pipes. That said titanium cool may be...but no extra ponies I'm afraid.

Here's some dyno stuff on various systems from the established leader in hot R12S (on "average" > a full system + RapidBike +... = ~ 128 real ponies, plus a terrible boost on middle range, where it matters the most).
