they do sound cool, but not in the way theyre meant to.
wheres the VTEC noise, the change in note when it engages??? theyre just the same noise right through the rev range, its meant to kick in and have its own noise like CTR Lees does. (i know, nobody else has heard it, but any of the EP3 owners with an AEM V2 or similar will know what i mean!!)
The cars in that vid are in tec most of the time. Remember i-VTEC changeover in the K20 is a lot smoother than original VTEC, plus fitting induction and exhaust upgrades actually smooths it out a little bit more in my experience.
I think these guys are running Spec IIIs or Pro-Specs, I've got a Spec IV (quieter than these pipes) and an AEM V2 and you (and those around you) know when you're hitting tec
