I think the may issue is more fun to read..hehehe. Im using alta CAi. Hmmm, you definately cant get borla, quiclsilver ,miltek over here. But.... it you dont mind driving down to Singapore, you can get the Remus exhaust for about SGD$1800. Don't get the AC exhaust, it is made by Remus anyway but more expensive. If you dont mind spending... go for it. The price is close to 5K.

Might as well drive down to Singapore and have fun driving home with new system, can go shopping too!
If you dont mind using the current tailpipe but better sound and makes your car go lighter... do the one-ball
mod. The sound is damn nice.... you'll have some 'pop' sound when you let off the throttle.
