    Manufacturer's Part Number:
    Rated 5 out of 5 by from Holly TBI Easy to install, only took about 15 mins Very easy to install. Some people had talked about having to bend the EGR bracket but mine was already out of the way. Seems to have added some power over 300 RPM. Much smoother Idell and transition is good as well. I also added the Flowtech Shorty Headers that were a direct fit and seems to have helped also
