FInd out what their exact setup is. My guess is you've heard them with ORY's and a Borla or GMMG or some other intended to be loud exaust. The header add quality to the sound of your exaust. The Cat back you choose makes the difference in loudness.

I like the sound of my Corsa as it is, but I know adding headers with a cam would give me about 50-60 hp.... decisions decisions....
