Pipe for GT2

[maximumNRG]

Hey guys,

I know the Smoothy is one of the best pipes for GT2s, since it give it a nice workable power band, but I wanted to know if there are any other pipes that give of the same, or similar effect as the Smoothy pipe, since its sometimes just too difficult to come by.

I also wanted to ask if anyone's tried out the carbon fiber exhaust from Vantage. I've only got the RTR pipe on mine so its not easy for me to relate it to the Vantage if I were to get it, but I'd like your insight on this.
