Without a catalytic converter? I ask because a week ago the catalyst material in mine cracked, which produced a horrible rattling from idle to 2000rpms. So I took it to the shop, busted out the material, and welded in a straight pipe end to end. I am coming back to Texas soon, and will have to pass before I can register it.
Also, anyone that installed a test pipe, did you experiance a much quieter vtec engagement? and quiter idle? My vtec is like butter now, and butt dyno says it flows a bit nicer up top, and idles sooo much quieter.
