Right im thinking of changing my exhaust, ive got a 5zeigen on at the moment and it sounds lovely but i think its time to change to something quieter and maby having a sports cat in it too. Id still like a full performance system but unsure what to get. One of my mates has an HKS silent hi-power (think thats what its called) it sounds nice, looks good and has a cat in but dont know alot about them, or if anyone could point me to some other alternatives that would be good
