Review on Thermo Tec 18075 Black Heat Sleeve by Eric Mahendra

According to my experience, this heat sleeve is far from satisfactory. Despite its promises, it failed to effectively block the heat emitted from my automotive exhaust. The only pro I can say is that its black color is aesthetically pleasing. However, the cons outweigh it, as it didn't serve its purpose and was a complete waste of money. Thermo Tec should improve the quality of their products to live up to their customers' expectations.
