kakimoto full-mega single n1
thats wat u call an exhaust! noise & power wise... aahh i miss the noise it use to make, it didnt drone either it was the perfect noise esp once you open it up in the higher revs.. the noise was so intimidating would scare ppl at idle already hahha
oh forgot to add i think it was 110db@4800rpm tho with a full turbo back system on a r33 gtst.. pretty sure it'll sound the same on a 34.
