Anyone have any internal Stillen contacts?

I send email to them asking technical info about products and all I get is the standard reply from Margaret that they have no information on the products but they do have these other great products I can buy.

I'm tring to find out if the 2006 G35 Engine Dampener and Brake cylinder brace fit the 2007??

Anyone know how much the mast cylinder setup has changed if any between the 06 and 07 engine bay??

The engine dampener is tricky because of the second intake tube, not sure it it will interfere with it. Any thoughts on this one?? Does the dampener sit low enough to be out of the way of the intake pipe?

Frustrating seeing as I live and work less than 15 minutes from them and offer several times to bring my car over so we can see if it would work and all I get is the standard sale response from them..

Might have to just order it and try then return it if it doesn't fit. Anyone know their return policy??
