Wgnc34 Stagea Exhaust Questions

[hks33]

Hey sau,

Just recently purchased a 1999 RS four S (dayz edition). Looking at my next catback exhaust system for the car, it came with a split dump pipe and a custom welded front pipe. I need something of high performance and nice decent note to the exhaust.. the following link shows the systems im looking at http://www.nengun.com/search/#t:n:u;v:90049;c:6;g:1

Kakimoto R

Kakimoto Full mega N1

HKS hi-power (used on my R33 skyline)

HKS silent hi-power

Greddy power extreme-GS

Just need some opinions on which is the best system i can buy, not too concerned about price just quality

Best regards chris.
