Actually it will increase your power "a little bit" but probably not enough
to be perceived. JetHot is also an insulator, and acts a thermal barrier to
keep the heat of the exhaust gases inside the manifold. This should keep
the exhaust gas velocity slightly higher, which means they flow thought your
manifold and out your tailpipe quicker equating to less back pressure. It
probably has a greater effect when those professional racers are using
professional racing motors, and I would expect that the greater scavenging
effect this provides is worth a few extra horsepower to them. For our
TRs... you'll probably see a 0.02hp gain!
