    26170 is rated 1.0 out of 5 by 1.
    Rated 1 out of 5 by from poor design and fabrication I installed the 500-26170 headers on my 1970 GTO. The heads were out of the car so to install the headers was easier. After driving my car for a long period of time the headers started to leak. The way two of the pipes are bent it is almost impossible to get a wrench on two of the bolts to tighten. The design and fabrication is very poor. as of now I have a poor sounding exhaust system. Muffler shop want $400.00 to correct the problem. Headed bolts will loosen up over time so I can buy new headers or live with the poor design and fabrication. What should I do?
