I kinda assumed it was a custom job done specifically for your rig. (Since there are no production info available anywhere online).
As for the 2wd colorados I am aware that they needed minor tweaking, (even catbacks sometimes need to be modded abit sometimes to fit perfectly) but the 4wd application is what interests us.
Aah, thats where communication is key :wink:, mine was a once off, but that was a once off for the headers to be ceramic powder coated

. They have done a few V8 already, and have a template, so as soon as a request comes in they have headers made up according to their template, and then you just go there for fitment. No tweeking whatsoever was required on the headers when they fitted it to my H3. The tricky bit came when they had to custom build the freeflow from the headers to the back of the Hummer as I was quite specific what I wanted :shifty:.
So you can rest assure on you S.A. built H3 V8 the Viper headers will fit perfectly. As for the American built Alpha I cant say, due to the left - right driving configuration.
And as an after thought, in South Africa people aren't big on online advertisement yet, and believe me its a frustration, if you do get a product online 99.99% of the time there's no price:gaah:
P.S. the headers have their mounting points for the cat sensors, so if you order ask them to include the mini cat foolers (little piece fitted between header and sensor to fool the PCM into thinking there is still a cat installed :thumbs
