I am installing a custom turbo setup that i put together on my 99 civic hb cx. I'm new to turbocharging as this is my first attempt. My question is where can i find a downpipe or how hard is it to make one. Can my local muffler shop make me one? or is there somewhere i can buy one cause i have looked but all my efforts were in vain. BTW pardon my ignorance and thanx in advance.
