You are an idiot for cutting out your catalytic converter. You WONT gain any power or throttle response, you are just imagining it. A cat reduces the flow of exhaust negligibly and does nothing more than reduce harmful emissions like carbon monoxide. The small amount of throttle response may have come from upgrading from a stock to aftermarket muffler, but not from removing your cat. Put it back on, you can't pass an emission test without it, and depending where you live, it's illegal.

i know its illegal haha i wanted the sound

[daisyandsteve]

notice any increase in power there bro?

I got a 92 and the muffler is fucked, leaks everywhere including the cat its going to be cut out.

[trusty317]

the acceleration is better without the cat thats about it lol.

[johnpsmith84]

so what is the real setup?

[trusty317]

I deleted the cat, and put a pipe there, and the exhaust is just a flowmaster 40s haha taking out the cat helps the sound a lot

1994 4 runner sounds better with holes in the muffler truts me

[hooverskins]

sooo how many clutches have you gone through driving like that

[AZtwoNE]

I feel sorry for your clutch

@4KSE i got more grunt out of mine when i deleted it why would they take them off for raceing duh and they sound way meaner dont be such a girl but mine sounds alot better than that thing here buy a real muffler aka borla and some headers

Im leaving the cat on my 4runner when I put an exhaust on. Just not worth the effort, and it wouldnt pass the etest w/ out one!

[Bosmob]

I really can't here the difference sorry to say...

I have a stock 93 with the 3.0 and it sounds the exact same.

All 3.0's are just fucking gutless!

i would like to know how much buy perecentage does the catalytic converter reduce emissions, what are they made out of, and can they be recycled for another purpose, im just wondering if the car makers maybe should find a better way, because lately the stuff we are lead to believe that is good for the enviroment is really terrible in the long run.

@4KSE I would have to disagree with you. As much as I don't want to admit it there are plenty of dynos that prove catalytic converters do cause loss of horsepower but you are correct today's cats are very efficient and the environmental price to performance is not worth it.

the reason the 3vz is prone to blowing head gaskets IS BECAUSE OF HEAT!

BUT!!!! it's because of the stock crossover pipe, i took mine off and ran duals to a dual inlet single outlet muffler and it sounds and runs incredible lol
