Is it possible to remove the catalytic converter to increase horsepower??? How much horsepower gain??? If so, will that make the car unbearably loud?

Probly will yield a few horses. Loud, yes, now if you remove the resonator it becomes buzzy which sounds a little ricey.

yes i also want to remove my high flow cat. but i dont want a CEL to go off. any way around this? thanks pc

I removed mine, and it really lets the engine breath better...
Just expect to run out of fuel faster... I want to lean it a little bit, but I dont wanna put my engine at risk of detonations while testing...


no cat.+ aftermarket muffler Sounds al most the same as the setup cat+ aftermarket muffler...

Believe me the cat is the biggest restriction in the exhaust system...

Fortunatetly I my car is not US based so I dont have any CEL problems...

you can purchase something from one manufacturer that I dont remmember right now, it gets rid of that cel stuff, it's a company I heard from Coolmiketu ....

the company is Split Second

I want the kazuma, but i think it is too loud and it will make air pullution

 

[Hungster]

[Tung]

I was wondering the same thing at one time and a guy here said he could help.

I have an aftermarket muffler with no cat or resonator, and when most people hear it they think i had an engine swap....

na the kazuma isnt that loud when shifting in low RPM's but its a great mod i like it way more than my TRD...

Just install high flow cat.. no CEL problem at all....
Having Kazuma has nothing to do with air pollution..
Muffler doesn't do thing for the air pollution.. it's just noise reduction....
CAT which actually helps the lower the pollution. but burning off unburned fuel...
