what is that tape I see on exhausts?

Colder air is more dense than hotter air. More air, more HP...

Except for the fact that it's on the exhaust, which means the amount of air flowing through is regulated by how much is in the cylinder. Not how hot the pipes are.

I believe the purpose is for improved exaust gas flow. The theory is that hotter gases are less dense and therefore flow betterer. The tape insulates and keeps the heat focused into the pipe.

Be certain that the tape is what you want because when you remove it there could be damage to the finish of the pipe. If it's stainless you can sand off the residue and polish the pipe. If it's chrome it's likely that the chrome could be discolored.

It does look cool. If you like the look you can get it at Summit auto parts. They have a web site.

All I see this wrap doing is keeping the heat from radiating from the pipes on to the engine; therefore, keeping the engine cooler. And the way it looks is a matter of opinion, which we are all entitled to. I don't really like it.

I'm mostly inclined to agree with Niterider in terms of the cooling effect. Though I think it looks pretty spiffy if done up right.
