How is this correct??
 

I was lookin thru for exhaust set ups and I found this from mazdatrix's site? It claims a 28% increase in rwhp with the complete dual exhasut set up for the na FC?? Does anyone have this setup?

And the racing beat one is $1300!!! What the hell!

I wonder if they are obnoxiously loud. It does include twin pre-silencers, but i cant ell from the vid whether it would be mind-numbing to drive

Racing beat mufflers are extremely hideous. who wants these 5" long skinny tips coming out the back of their car. It looks too much like stock to cost 1200 bucks.

Yeah now that I look at it, it is really gross (like 2 tiny pensises coming out of the back). :) But you think it can pull that kind of power out of the car? 28% increase?! Sounds too good to be true.
