04 Taco v6 upgrades

After looking at tons of threads. Im contemplating a cat back exhaust... Can I install the urd device, gut my converters, and put the magnaflow flow through muffler with no problems?? Also what is the difference between the metal bodied kn air intake and the plastic one?

 

All that stuff is a waste of money IMO go with a supercharger if you want added performance. I have CAI,trd headers, trd cat back and it feels no differant power wise than my 97 4runner with only a CAI. Ive read plastic is better but i cant remember the reason also id consider Airaid i have both K&N and Airaid on my trucks the airaid is better quality. but replace the oil filter with a amsoil dryflow filter.
This is my 4runner with a k&n pipe and amsoil filter

My tacoma with airaid gonna be changing that filter to amsoil as well

 

I appreciate the feed back. The dry fiter will help out with dusty conditions a little better as well. Thanks

 

not sure why you would need the URD tuner...you hardly changing anything. If you gut the cats you'll need to get the O2 simulator from URD tho.

All in all..not gonna get massive gains. You want more power, forced air induction is the only way your gonna get it. AKA..Supercharger or Turbo

 

Totally understandable.. I have 171k one the ol beast. So im trying to prolong her life span. have recent gathered up suspension parts as well... Toy teck coilover. LR uca. Energy poly bushings... Still contemplating my rear end. Prolly just going OME leafs and shackles from wheeler. Seems to be the cheapest. i am learning tho.. converted Power Stroke junky
