I just got finished installing my new B pipes that remove the secondary cats. I bought them from RockAuto. They are stock replacements from 99-00 V6 Frontiers and will bolt up to 01-04 perfectly. They cost me about $100 total shipped and took me about 2 hours to install. Here are the part #s:
Pass side - 53345
Driver side - 54338
You can go Walker Exhaust Solutions From The Industry Leader and cross reference your truck just to make sure they will fit.
I immediately noticed how much better my Magnaflow sounded as soon as I fired it up and call tell the truck is definatly breathing better. The I.D. of the pipe is the same as stock the piping is double walled with an air gap for an integrated heat shield. The appearance is factory and I had no problem hooking the O2 sensors back up.
If anyone is interested I will throw up some pics.
BTW, my truck is an 01 Desert Runner Auto.
