here's what i did
went to the local muffler shop and had them cut out the y-pipe and i ran duals from there on back. i used 18 inch glasspacks for the mufflers. truck sounds great and i picked up 1.75 mpg on the hwy. can tell a big difference in mid range and top end power. my truck is a 97 4x4 with 4.6 and tow package.
