hi guys

i know its all been covered before...

but its more concerned about the sound and performance.

however i want to keep mine as stock looking,sound as possible and

no drone of exhaust inside the cabin..

only thing i came up with was (mines VZ V6 170?) putting V8 catback system in

some said it fits up straight away no mods,

some said might need mods

some said makes no difference and this and that

so if anyone ever done it or knows about it

pplease give me an idea..

thanks~!
