I HAVE ONE ON MY R33 GTR it sound good and is no were neer as loud as my old exhaust .so say my neabours ....Hi i currently have a full titanium exhaust (unknown make) which is just too loud when the engine is idling. But it does sounds sweet when giving it the beans , i was just wondering if anybody has had any experience with these HKS silent systems? I've looked on Youtube and have found a couple of vids of the sound when idling but cant find any when the car is driving at 'higher speeds'. Do they sound any good? (car is a R34 GTR btw)
its quiet when idle ing and still loud when it needs to be .
