Hmm... bizarre thread.

Basic thing here is that in real terms Callway, SLP and Hennessey are all selling variations on a theme of addons at premium prices which put their products in line with the price of a Z06.

While some folks may want to spend the amount of money for the specific badge and the associated assurance that the parts all play nice together - other folks can see that broadly speaking it is the same CAI, exhaust/headers and supercharger kits that they can get elsewhere and all the emroidered headrests, carpet mats and serial numbered dash plates are just fluff if you have the extra cash.
To each their own but fact is that there is a lot of well established "builds" now on the camaro especially since it is built on a well proven LS3 base engine.

Each major builder will argue about their specific element of special engineering pixie dust but reality is that there is a lot of commonality and quite a bit of cost adder on the parts for the privilege of buying the brand name (I am still recovering from hearing that Hennesey wants $500 for fitting their $500 front and rear sway bars.... 12 nuts total / $500.... wow !)
