CORP Tuning or COBB Tuning?
Found this on eBay.
Priced at $99 bucks with free postage.

These look eerily similar to the ones COBB sells on their site......at twice the price PLUS postage.

Also note the logo the ebay company uses (look familiar?) and that they specifically say 'we are the manufacturer not the trading company' ........

I don't think it takes a genius to join the dots, and you'd be naive to think that COBB manufactures their own - so if you want to save a few bucks ...... go for the eBay option i reckon!
