Sounds good doesn't it, great engine the K24 I did enjoy that car.
I haven't done mine on the Civic yet, had a go but got as far as removing the rubber elbow, realised all my tools are in the loft when I realised I needed to remove the battery and then lack of bothered kicked in. I'll do it at some point.
I tried the wheel arch method first but I have no idea how you got that bulky thing out from that small gap, so I went the whole bumper off route (It was more fun to do since i've never taken a bumper off a car before)
At first when I blipped the throttle I was a little disappointed, How little did I know when I pinned it down to the neutral limiter, my god its loud, made my dad jump out his skin haha.
I like that it still sounds stock when driving normally cause i'm not sure if I could put up with it droning or anything at 3k rpm, But as soon as you pin that throttle down to the floor its like a new car I couldn't stop giggling like a little girl.
One thing that does disappoint me a little, I was hoping the vtec crossover would be more noticeable but alas its still quite subtle, there's something there but unless you're actually listening for it you wouldn't know, Guess that's the characteristic of the K24Z3
I've heard people using silcone piping to join the airbox pipe to the pipe the resonator connects to, think its work doing?
