Re: Catalytic Converter?

2004-2006 4wd = 4 cats, you can remove (or gut) the two rear cats with no issues...just different sound and slight power increase
2004-2006 2wd = 2 cats below the manifolds, and 2 resonators in place of where the ^above rear cats are on the 4wd...you can remove the resonators, but i'm not sure how much that may change anything really

2007+ all have 4 cats, and you can remove (or gut) the two rears with no issues like the 4wd above...same results too

removing the front cats on any model with almost definitely throw a check engine light...but there are ways around that. others will chime in, deerslayer comes to mind...he just gutted his front cats and had some good results from it. myself, i have only removed the rears and had them replaced with pipe....noticeable sound difference, MAYBE a power increase...can't really tell.

Search Walker Direct Fit b-pipes, you can replace your OEM b-pipe with cats in them with these Walker B-pipes that do not have cats. It will run you about $90 for the b-pipes

I have no proof in a timeslip yet but gutting the fronts gave me more power. I can spin the tires from 25mph now. Before gutting them I couldn't. Did a 60-100 the other day and it pulled like a mofo the whole time. I'll go to the track soon and find out how much I gained.

Re: Catalytic Converter?

Any updates on gutting the front cats? Does it bring up any codes or does it create any performance problems?

Re: Catalytic Converter?

What about in Cali? Can you remove the rear cats and pass smog easily? If so, why even have 2 more cats?

Roll-Tide,

So just to be sure, you removed the rear cats on your titan and replaced them with pipes right? And you had no SES light or codes come up right? I want to gut my rear cats on my 4x4 but before I do it I want to be sure that there are people out there that have done this without any issues...

You are right, but if you have the rear cats gutted they can't tell unless they remove the pipe and do a visual inspection of the inside and that just doesn't happen. The front cats, don't mess with those...

Re: Catalytic Converter?

Are there any threads/vids/pics on how to gut the rear cats?

If there's anybody that can screw a simple job up, it's me!

Or you can save your stock pipes and I can build you some pipes to delete the secondary cats. If you ever need to go back stock you can. Just wanted to run that by you.

I have a 06 2wd I am about to do the exhaust. In all my previous trucks I have used flowmaster always been really happy with the sound but when I do the titan I want the sound and the power. Can I still stay with flowmaster? And what can I do with my cats to gain power as well?
