After driving mango around for a while, i discover that mango's 4age-20v wasn't revving nicely durnig 3k~5k. Than McGuyver said it might be the 4-2-1 mango currently using is not breathing well. since the cam had higher lift and more air going into the engine. So something had to be done to the exhaust ^_^. A trip to chean exhaust is indeed.
So i retrieve the custom made 4age-20V 4-1 header for FR setting with ceramic coating! 
and took out the old 4-2-1 sr20-mod-ed with 4age-20v FF-header.
everything took out fairy easy with lot's of hand space in mango's engine chamber ^.^ 
but my O2 sensor wasn't happy to go into the header... for it's from sr20.... some cutting is in order. (sorry, no photo for the cutting part :P
the curve fit in nicely ^.^ big hurry for the japs.
bending the 2.5" soft-pipe to fit into the 2.2" pipe i'm using from front to rear.
Everything fits in and working nicely~ and mango-sings~!
