Hey guys... I have recently purchased a Prelude...Its basically stock except some clear tail-lights that came with it, a pioneer cd player,amp & some 6x9s... ive just had a major service done on it ( 50 ...ouch! ) and other than that its pretty much as per factory. However, ive been looking into some mods & i spoke to a guy at a local performance store... apparently the VTEC controller are pretty much useless until you start changing cams & stuff... so i was wonder a few things.... - Is there any benefit in getting af ull MUGEN exhaust system rathen than a custom one from an exaust company?....how much difference does it make on the road?... i mean, i understand the power gains, but physically on the road does it really relate to any performance? -intake system ... is it worth my trouble? ive heard of really minimal gains & apparently it makes the sound of the car a bit rough... - whats the quickest 0-100 time i can expect from upgrading the intake & exhaust... i'm unsure of the performance you get back from VTECS, ive had a turbo and it was quite a reasonable difference with a boost up too...so any info guys?
