Well im trying to sqeeze more horsepower out of my K8, (Dont Say KL-ZE swap lol)

anyway i was wondering what would be involved in eliminating the cat. converter

And the biggest question what would i see from that ?

Well you cut it out and weld or clamp a piece of straight pipe in there...you might see 2 or 3 whp from the switch and from what I hear better gas mileage... the downside...you'll be louder and not able to be inspected

I think there is a guy on ebay who was selling straight pipes for 30 bucks or something. You might notice a bit better gas milage, espically if your currrent cat is clogged, power isnt really noticable, maybe a little more top end, but the most noticable is the volume. You will hear your car for daaaaays. I kinda like the noise but it is really really loud.

k yea my main question in it (which is answered now) was if there was a second o2 sensor in it, or after it

Depends where you are. But in Ontario if a cop see's you have no cat its a $300 fine. So watch out. Best bet is to just get a High flow cat and keep it legal.

John

take your CAT out rip everyting out of it and put it back in then the cops cant do d--- all.

or bribe the inspentcion terminal like i do.

There was an article in one of my car magazines a month or two ago comparing horsepoer from stock cat, high flow cat, or test pipe. The test pipe only made one horsepower over high flow cat. It was a joke. Magnaflow cats are only $60 on eBay. In this instance, it doesn't make any sense to not keep it legal.

well i live in washington state, they dont test emissions here so, instead of pay for a new one why not just take it off .

There may not be emmions by law there needs to be a cat on the car.

Yep. Even though they don't 'test', if your car doesn't have a catalytic converter, a cop can bust your balls over it.

trust me man cops dont just pull you over cuz you dont have a cat it might be because you have a massive cannon on the back of your car with no resonators like the rest of the honda F@#$ nation. Cops cant tell if you have a cat or not just by the way your car sounds, there are to many diferent typs of exhausts and muffler and so on but if the cop was real good he could smeel the diference in the octain. I got a few cops in the family and ive asked them numerouse times about it and they say not to worry about it the only way they would try to ding you for something like that is if you were being an a--hole and they wanted to ding you for everyhting they could. Its up to you man come stated/provinces have manditory checks but if there isnt dont wast your money on a cat.

Yeah, if you don't have emissions testing, just pound the guts out of your cat, then put it back. It may only get you one hp over a high-flow, but it will save you 60 bucks!

And FYI, it won't make your car hardly any louder unless you already have a really loud exhaust.

lol i mite want to be careful though my car's muffler is a custom "Home Made" lol, the person that owned it before me cut all the s--- out of it, and my car also has a blowen resinator.

i'm sure you'd gain more than 1hp if your 10-15 year old cat was clogged, i got a hi-flo put in with my exhaust...., loud but not tinny
