Default Who's bought one of these exhausts?

Anyone bought a Full Spectrum Performance exhaust system?

They've got a 5" system available for $355 shipped to my door. I sent them an email regarding if there would be a loss of power with stock to minor mods and this is how they responded:

"No, Diesels do not react to big exhaust like a gas engine. The turbo reacts (spools up) due to a pressure differential across the exhaust turbine. The higher the manifold (turbine drive) pressure and the lower the exhaust back pressure the better for a quicker spool up that equals low end power. That being said, you should go with the best flowing exhaust that you can in order to gain power and lower EGT. The only folks that will tell you that a turbo needs back pressure are uneducated in the realities of turbocharger performance. A gas engine needs a tuned exhaust system to help scavenge and regulate the exhaust pulse from the exhaust port going too big or too small in this case will dramatically affect power. With a diesel exhaust bigger really is better. unless you have a GM variable vein turbo but I leave those to the Chevy folks.

Thanks,
Tom
FSP"

I was quite impressed by the response, so I'm interested in buying the system. Before I take the plunge, does anyone have any input about this particular system?

this place is less than 10 miles from my house....i went by there to buy a system, and i didn't want to pay freight....
the liar says in his ebay ad that he has 10 of them in stock......well it turns out he doesn't have any, and you have to pay the $65.00 freight even if you pick it up at his door..... pissed me off...
