Wrapping exhaust and intake

[PKozlowski]

Ok I have a question for you.

I was looking around the web and found somthing interesting.
I don't know if I believe the claims(I know I don't) or not.

A company is claiming that if you use they're product
which is basically an exhaust manifold blanket and wrap the
turbo and exhaust in the tape you will realize nice gains
in performance and MPG. They also wrap the intake side also.

I took out the actual product name(I don't want sued)

Here is one quote from the company.
“Not only have I seen increased fuel efficiency with (Product), and increased power, but a wide array of other benefits as well, less auxiliary for running, lower engine coolant temperature, lower engine oil temperature, lower RPM’s at highway cruising speed, less engine noise coming into the passenger compartment, and increased air conditioning performance.”

"lower RPM’s at highway cruising speed"

I think this is just total BS.

Now if I am driving a 6 speed manual tranny and I'm doing
2200 rpms at 75 mph.
Logic tells me that if I drop my rpms I'm also going to go slower!

How many of you think this claim is just crap? Chime in!
