Exhaust

I am looking in to buying the hks turbo exhaust for my eclipse. I just want to know if anyone else who may have it. How much hp gain and how did it sound?

doesnt give you more than a few hp, you wont notice it much. once you start unrestricting your entire exhaust/intake path (new ic pipes, front mount, downpipe) then you can turn up the boost and see more hp.
