true, take note of it. i lost a fair bit of low end with the 2.5" system. but it was worth it IMO. when you are pushing it the car lives int the rev band from about 5800-8000. so it's all good for drag racing, or tracking...

lost a little bit of urge around town though. but thats doesn't worry me.

as a general rule of thumb you would lose either top-end or low end...in a perfect world you could gain both...if not maintain power output....

a larger ID (inner diameter) B-pipe is what you really want as VTEC likes to breath...

cheers

fanx heaps

lots and lots of secret stuff :wink:

nah... just a header, intake and exhaust. tacked on some pvc piping as cold air ducting to my stock airbox. changed the paper filter for a k&n filter (ru2820 from memory). i am going to get new secondaries made up for the header, i'm going to ask them to make them shorter and go into a 2.5" collector, rather than the 2" one that is on there at the moment.
cams and cam gears on order... and i'm still deciding on what route to go down in the way of electronics. powerfc, unichip, chipped ecu, etc.

It would be interesting to see how you would go on the strip.... :lol:

any pics??

Slim,

Are you going to keep the car or keep doing it up?

i'll probably stop after i finnish the next lot of work... i'm more or less happy with the handling setup. and i think there will be enough power to keep me happy when the cams are installed and tuned.
