Exhaust Header Help!!!

I just installed a ceramic HP Motorsports header. (Exact replica of the DC sports bolt-on 2001 Civic Header).
However, I overtourqed the two bolts that connect the flanges of the header and the downpipe. Now one of the bolts has broken off, and the other bolt is bent. I ordered two new ones from a Honda dealership, but they asked me to find out if the header thread pattern is the same for the stock bolts or do I need new ones. Does anyone know if the thread pattern to the Hp motorsports (or DC Sports) header is the same as the stock header?

They should be the same bolts....I didn't have any trouble with mine, so I would suggest, just getting the new bolts from
Honda and get the torque specs and try it again. You're gonna dig that header...I have the DC 4-1 Ceramics and they ROCK !!
Good Luck man !!

If you were able to put them on, then they are the same pattern.

Man, I recomend you take your car's head to a shop to get it checked and make shure you get everything right(threads) Or just drive it there.[IMG]i/expressions/face-icon-small-wink.gif[/IMG]
