rb25neo, they have been doing this for many years and yes they dyno before and after to prove the results. The cost for HKS silent exhaust, 3" catco hiflow cat and blitz 3" front pipe alone cost $1750 and still the cost of fitting if your not doing it yourself so probably around the $2000 price range anyways. Have a look for yourself http://www.cesracing.com.au/ these guys have a serious reputation and have held it for many many years now.

Mate the Jap ones are not all there cracked up to be, your mostly paying for sticker name. I have been going through the same dilema at the moment. In my opinion I think the Jap sticker brands are great for coolers and add ons like oil catch tank etc. But with price not being your deciding factor I would say you cant go past CES racing. I have been looking for the best quality and flow myself without price considerations and no one but CES racing will give you guaranteed kw increase. Full CES 3"stainless system with ceramic coated twin dump pipe for $2640. Im booked in to get mine fitted in 2 weeks time. Guaranteed 40kw increase at the wheels, best systems around for quality and performance I reckon
