I just installed my apex'i exhaust and when I took off the factory exhaust I screwed up the cat. conv. If I get a high flow cat will it have a hole for the o2 sensor...or is it possible to make one/ Is it my best bet to buy a new oem cat or just put a high flow on ein. I can get a ractive(toucan industires) high flow resonator for like 75.00. But I do not know if it has a hole for 02. I do not want my chk eng. light on so any info is appreciated.

 

You could get an O2 simulator if you run an aftermaket converter or straight pipe. I'm not aware of any convertors with the 2nd O2 sensor bung, but you could also have one welded on.

 

Just cut a hole in the new cat and weld it in??..I need to pass emiisions so thatis also a factor. What is a testpipe? and an os simulator?
Thanks

Not sure about mounting an O2 sensor on a new converter.

A test pipe is a piece of pipe that replaces the converter - not legal.

An O2 simulator send the ECU a message saying there's a converter installed.

 

Random Technology hi-flow replacement cats should have all the provisions your OEM cat has for a proper bolt-on installation. They're also 50-state legal.

 

So I want to keep a cat..so this means would it be better to buy the toucan one i described or just an oem one...-sorry so many questions but dont know about this stuff..and need
one soon.

 

buy one of those cheap hi flow cats for a 96-00 hatch

but be warned the cat's that look like obx mufflers sound like ****

they have a socket built it for an o2

by the way-what type of car and trim?

they sell o2 bungs that you can have welded on.

 

Of course there are highflow cats/test pipes with the second o2 bung. You every obd2 car owner just ignores the secondary o2? I've had both on my cars, got them from testpipes.com. If you are patient with the lady who answers the phones, you will get a quality product. Call, and you will see what I mean.

 

2000civic 2dr ex 1.6 just installed the apexi worls sport

What are the actual benefits of high flow cat...can u give me some prices for what I should be paying....how bad is the oem one?

 

I'd say waste you hard earned money on something else and have your cat fixed at a muffler shop( you messed up the flange correct?) that money can go towards something else.

i say go with this and call it a day.

 

yes.....I messed up the flange preety bad while I was trying to get the rusted *** bolts out...how much worst case it would run me to get it fixed....the flange still has two bolts stuck in but the bolts are grinded away and there is a hole that is all messeed up near the top of the flange.....

come down south and I'll fix it for 25 bucks at my shop.

 

thanks for the info..i take to a shop on monday and see what they say..if they try to rape me i will check somewhere else...I guess i am just embarassed to have them see my rig job, i wanted my exhaust at least connected on there.. i have one bolt holding the cat to mid pipe right now and feel like an idiot.

 

you should get your old one taken off and get the one i suggested it comes with the new flanges and a o2 bung.

 

the price i take it is like 180 for it...do u think it is worth it? I really do nto know the difference between that one and oem

 

the price depends if you are going to need new flanges to bolt it to your midpipe and header.

if you need the flanges it would be around 155
if you dont need them it will be around 90

i would highly suggest you get it with the flanges,

i think a good hi flow cat is worth the money, it will increase performance and the tone of your exhaust.

i was saying the cat with flanges is 155 and the cat without flanges is 90

Random Technology cat is around $200

OEM cat is around $800

ivan is right if you can fix it at the muffler shop go for it, but if not get a good quality hi flow cat with flanges.
