Frankyflo thanks for resurrecting this thread as I have been trying to find the best place to order a Magnaflow exhaust. I just ordered kit 16518 from Hottexhaust.com for $391.00 and free shipping. Your coupon veedub does still work if anyone is looking to order one.

 

You guys might want to google these things. I just found the MagnaFlow 16615 on a popular Book selling site for $332.06 I'm just starting to read these threads and trying to get ideas for what exhaust to put on my 06 5.4

 

I did google my system and that popular book site wants $495.00. The one you listed doesnt fit my truck and its not the style I wanted. But youre right with a little research you can save a lot of money.
