Dougs Headers

I run dougs headers and pypes 2 1/2" exhaust all the way out the back. However I don't use the gas tank. I have a 18 gallon fuel cell in the trunk. Benefit of this is the tail pypes are much easier to install the way you want. Also the only hiccup I found on the 67 fish for the headers is the steering column. My car had power steering. Converted to manual. I ended up cutting the outer flange of the column back 3". Then I installed a bearing to replace the white bushing. #7 primary pipe on header is 1/16" away from column and would eventually melt the plastic bushing. And if you don't have your motor chained down, it will rattle against your steering column. That's the only problem I had. Oh yeah I have no kick down linkage. I run RMV in my tranny. Good luck and take your time.
