i need to put something in place of my cat, and i found lots of test pipes but they all have the o2 sensor bung and i dont have any o2 sensors on my cat, if anyone can tell me how to modify that or what i can do thanks

 

put a bolt in it

 

LOL you said bung.

Anyways, your car is a 90 correct? Look here, this is what im running on my 240, same exact thing. sounds good too.

thats what the web site said it was a bung, but anyway doesnt the resonator silence it or is it just a straight pipe

 

Better keep your cat and be prepared to put it on for e-check time. The first thing they did when I went for my e-check was take a mirror and check for a cat. Im from OH so i dont know if it differs state to state.

 

What a resonator does, as my dad explained, is the fiberglass helps silence the high frequencies, giving it a lower smoother tone. A straight pipe would give a fartier sound.

And by the way, the guy who said something bout emissions check, i dont think florida checks emissions do they? If so i would keep the cat in the garage so you can swap it when you need, but if you dont, put in that resonator. Ill post a pic of what mine looks like on the car if you'd like.

 

no we dont have emission checks but i wanna know if its going to be louder than my exhaust now

 

it will be louder, but not in the ricey civid louder, the deep tones will be more pronounced. The high tones will not be as strong as if you ran a 3" pipe in the place of your cat. But, it wont be much louder. maybe a few dB's. believe me, you wont be disappointed

 

well im gonna run the res. its a 2.25 inlet and outlet right?

 

im not sure, but it fit fine with no mods. So either its 2.25 or 2.5, but either way it worked fine. Ive had no problems with it.

 

thanks man , porlly woulda made a mistake going with the str8 pipe

 

yes, you would.

 

yay me and raine finally agree on somehting!

 

did u notice any power increase with the res. I heard that u can gain a few hp from taking out the cat and putting in a test pipe or w/e but when u go to the e-test u have to put ur cat back on.

 

We dont have emissions in louisiana! WOOT! anyways, yeah i do feel a few extra donkies under then hood
