afatt,
If not mistaken... long ago I changed all 16 lifters of mine for RM80 per piece brand new. IF ACQ says RM800 for 16 pieces, it's cheap.
Calvin,
Actually using a mid-muffler is more beneficial than bullets. If that way, use 2 also tak aper... minimal power loss on mid mufflers... but of course, less noise-reduction from it as well lar. A lot of vtecs use 2 mid mufflers on their exhausts.
*In case you guys not sure what a mid muffler is... it's like installing an N1 muffler to the mid pipes. =)
mediocre,
Get a rechip done to remove your rec cut. Those aren't expensive... i think somewhere around 300 bux. I haven't done it before, so I'm not sure of the exact price... but if not mistaken it's around there. Fueling I prefer to run on emanage, because it's much more 'tuner friendly' than rechip.
