I have a Pulsar GTi-R motor, and I'm planning to run 3' piping. I already have a 3in Downpipe from Sr20 Development. You should check out the website, they fabricated that, and an intake tube for me that both look and work great. 1-619-69turbo. Right now I'm running the stock exhaust with the turbo, maaddddd laggg. But it's really quiet...
Or you can check out their website, they have prices online:
