Heres some pics of the setup mind its all dirty as heck i gotta paint them.

 

ok, thanks, that helps, i was wondering what you did with the O2 sensors. now i see.

do you have a CEL?

im thinking about taking my back 2 cats out, but i just dont want a CEL.

 

buddy of mine got the o2 sensors from a guy he knows at a local shop back home in florida and got them for like 80 bucks and it makes the truck think it has the cats there and crap so it doesnt come in if im not mistaken thats what he told me.

 

You will get a CEL by removing your rear cats unless you make O2 sims or do the Gotts O2 mod to keep the light out.

 

in my sig is a video of what my setup sounds like: 2 hi flow cats that flow into an x-pipe and then into 2 super 44's with about 6" of pipe after the muffler before it is dumped

 

i dont have a muffler or rear cats just dumped exhaust and have never had a cel or anything... i have the 2004 5.4 3v.. . would my truck b better performance wise with a muffler? was looking at super 44 si/do... has drone in cab and getting on my nerves now..

 

what about 02 sims? anyone know where you can get them?

 

Alot of the mustang shops used to have them but now there almost impossible to get. why? but you can read up online on how to make some with resistors from radio shack. look up MIL eliminators

 

Rear cat removal with a CEL happening only qualifies for the 1997 - 2003 models. Not the 2004 - 2005. I didn't state that clearly, but I did now. I dont have my rear converters either.

 

think these will work on a f150?

The first ones say they're for stangs but will they work on a F150? And the second say they will not work on 05 and newer, What changed if anything on the f-150's from 04 to 05?

Sorry to kinda highjack your thread I'm just curious aswell

 

here is the link`s to the ones I made for my truck and they do work, you can buy all the stuff at radioshack for about $10 and they`re easy to make.

and I want to see some pics of those 5" tips I`ve always wondered how they would look on a F150

 

Will local muffler shops take out ur cats. If so how much? and is it really that much louder if u take them out.

 

some will, some won`t, luckily I found one that would but most of them will tell you they can take out the old cats and replace them but they cannot just cut out the old ones and put a pipe in, one shop told me that I could cut the cats out myself and he would put a pipe back in but that by law he could not cut out the cat, it also depends on where your at and the emission laws in that state, this is from my experience take it for what its worth and good luck

 

My exhaust shop will but they want aomthin like 150 per simulator or somthing
