Which one is better and what are differences between the two if any?

 

I have heard the DMH's are the best. Basically they are the same except a lot of people have had problems with the qtp's but i haven't heard any problems with the DMH's. So take that what its worth. Also the DMH come with a 4 year warrenty, and i have heard his customer service is great. They also are about to have a group buy.

 

DMH > QTP > McCord

 

I have the DMH and I am very happy with it.
I never heard anyone complian about a DMH but I have heard many folks complain about the other brands.

Here is my webpage its has video clips and write up of the DMH cutout install for my Borla.
