The tips are from Truck Ad Ons http://www.truckaddons.com/Catalog/subpages/toucan_tips01.htm number T564. Expensive but I think they're worth it. I would be kicking myself if I got something I didn't like just to save a few bucks.
All in all, the cost was:
Tips - $188.00
Dynomax Super Turbo (Summit Racing) - $44.50
Magnaflow Collector (Bestautopartsonline.com) - $82.84
Installation (Local Meineke Discount Mufflers...the guy did an awsome job making custom pipes) - $140.00
Total cost - $455.34
With less expensive tips, it would have been consideribly less for the whole job. I got lots of photos of the installation that I'll put online shortly.
