jsut had my car serviced, fresh oil and new filter .... and the inejn sounds very nice now LOL... also tehre was some nice cool fresh air atound 9pm last night
injen is probably better bang for your buck as it's much cheaper. leaves a big hole in your engine bay though. I've got the gruppeM and i think the sound is pretty amazing (no whistle). but if you're on a budget i'd go for injen.
i agree with you here .. gruppeM gives that different tone when vtec opens up.
