2 Questions:
(1) do they make a system for the 4.6is; and
(2) What is the price.

The ZTec exhaust fits all e53.

seems hokie, why wouldnt they post better videos if they wanted to sell that shiznit to make monay! hmmm....lets hear it boys, make a decent vid of the exhaust note, not some dudes bs'n bout hps, lol.

well the first link i head was vry strong nd I was impressed with the sound, but idk. It is cheaper than remus. It retails for around $850, I'm sure with group buy even less

Well i didnt hear the first vid because of the format and my apple is not playing it, anyone have any solution on how i can hear a good vid...Not a bad deal if we get a group buy together and some of us try it out.

I'm in with the group buy. But I need some more info on the product. Like will the exhaust start to rust within a year, what kind of performance boost should I see? Is it the same as a remus? This type of info...

someone would have to contact seller with a potential list of buyers

It has been done here before. Check the link:
