gutting rear cats?

anyone have a how to? i wanna keep the look of having cats on the truck...

anyone have any ideas of an easy way to gut the rear cats without firing up the torch and cutting up my new truck?

 

do they bolt on?

 

Better yet, get a set of DT short tubes and stay legal and have more power.

 

I am using a set of URD pipebomb pipes.
They have a big round thing on each side that looks like a cat.
The o2 sensors are in front of them so no codes have shown.
So I have a better flowing exhaust and still save the planet while getting 18 mpg!!!!!

 

Well, inspection isn't a big deal. I've seen people cut them off before... I've also Sean people cut them open... And take a hammer and prybar to them...

 

Pointless on a tacoma.

Now on a high performance vehicle...Yes.

I used to have a turbocharged honda accord before my tacoma and I actually didn't run a cat on it. 2.5" exhaust from the turbo back to the muffler. Surprisingly I was able to pass legitimately without one, gotta love OBD2 and the guy not doing a visual inspection because the car was too low to look under.

 

I use to own a 01 Tacoma. I live in alabama where there are little if any laws on emissions. So after I installed the header from downey I cut the first one off. No real issues other than the check engine light was always on. The code read backflow pressure below threshold in bank one. Well, I got use to that and could deal with it. A few years later I had issues with the second cat and ended up cutting it completely off. I noticed NO power gain whatsoever. All I noticed was that the truck was ridiculously loud!! If I had to do it all over again I would have never cut the first one off in the first place. Leave it on, it's there for a reason, not mention it helps protect the environment. Spend the money and get a high flow cat. Thats just my $0.02 anyway.

 

im also planning on doing a volant intake. if i did cut them off, would the intake make more backpressure on the exhaust to make it like the same pressure if they were there?

i know another guy on here cut his off and did an aeroturbine 2525xl and it sounded great, idk if he had problems with backpressure or not... what problems would u have if backpressure was incorrect?

 

I had an injen intake (see pics in my gallery if you like ) and my check engine light still stayed on. I never had any mechanical issues with the backpressure below threshold, nor do I know if I was creating any problems for the future. I was told by a shop that I could have the computer reprogrammed but I never did any of that mess. I shoulda left it the way it was or bought a high flow.

 

Yea, I think it probobly was you. How did you gut your cats? You lost power when you did it? If I just put on the muffler, will I get the same deep sound as if I cut the cats out?

 

what is your exact setup? your truck sounds amazing.

do you have pictures of the underside of your truck that you would share?

the 2525xl is only $120 on ebay. whats the purpose of the resonator, whats it do?

 

soo u have a 2525 and a resnator? not a 2525xl?

wouldnt a 2525xl be the same as a 2525 and a resonator?

 

which size resonator do youo have?

 

Where does the resonator go? On the aeroturbine website they only have a 3 inch? I need 6 of them?
