Re: Installed the Thorley headers today...
I hope that is all that it is; I disconnected the battery for 5 -10 mins, maybe I did not disconnect it long enough...I need to get the 2 my fault exhaust leaks fixed first and then go from there...wondering about the back pressure; the factory H pipe is still there and I so have a Magnaflow CB so I would think on a NA engine there is still enough back pressure...if I had no cats on the H or no muffler that might be it..I don't know...
