Review on Allstar Performance ALL34251 Header Wrap by Andy Jolley

There were cracked bolt holes on manifold flange. Basically this was used to connect it to reduce exhaust and sound power. Obviously spending a few hundred dollars and a few hours of work would be ideal, but this is a 20-year-old work truck. While it works great. I also had an oxygen sensor/engine fault check before I bandaged it. The reading returned to normal and the major fault changed to a minor fault/check engine, the light went out by itself.
