Like I said prove me wrong. Try explaining what your driving routine would be, maybe it is smaller. You may very well drive less, but without presenting any sort of claim, your remarks are without merit.

I could honestly care less, that's the difference between us. I just am amused from your remarks when you have absolutely no clue if you're right or wrong.....but for one Im not going to go rip my cat off for the measly amount of power you think you are gaining.....waste of time.

So now you could care less?

What happened to the tree hugging hippy that practically told us the world will end sooner if I drive my weekend car w/o a cat con. Did I mention my car has 200,000km on it, surely the original cat must've still been good.

You say I have know clue on if I'm right or wrong? I'm not the 1 basing my knowldge on what I read in magazines published by biased writers. I am capable of forming my own opinions. BTW I never told you to take off your cat, you asked a stimple question, I gave you a simple answer. You made me out to be some G.W. Bushesque environmental nazi, for suggesting against replacing an old cat with something else thats destined to fail.

Based on the knowledge of how much I drive my car and the probably accurate assumption on how much you use yours, I would say that you more likely are harder on the ecosystem than your arch Cat deleting nemesis... moi.

Dunt h8, appreciate, in a sense we're both tree huggin hippies.

I could care less what you think, not about the issue. You have no clue about your carbon footprint vs mine, and again, I could give a shit what you claim to think you know. I was commenting on how you sound foolish by thinking you know me when you have no clue.

You obviously are more concerned on arguing over the internet instead of reading what others have to say. Its ok, Im not the only one that feels the way I do....my point is removing your cat isnt worth what you make it out to be with your retort "um I getz 5hp's yozzz...weeee"......

and Im sure your going to cry if you dont get the last word....so go ahead, I proved my point, Im done with your childish games....eh

Crying???HAHAHAHA Actually i am enjoying a cold Canadian brewed beer.

Its a beautiful smog free day in Btown even with all those noxious fumes from my cat delete. Maybe you should enjoy a cold refreshing drink of your own, it will help calm you down after such a heated debate. LOL

I wasn't going out of my way to offend you, nor was I the 1 hurling sarcastic insults like " thats really smart". If you can't handle being criticized on how environmentally friendly you are then don't gripe about others removing their cat, plain and simple.

Enjoy your brewski, and the remainder of your day.

In defense of the horsepower angle, I believe our boosted engines rely less on back pressure than N/A engines do. The power gained from deleting the cat would be slight and in the higher RPM band. I do not think there is a chance for losing power from a cat delete.

Regardless of the topic, I'd just like to point out that the correct phrase is someone "couldn't care less"...

If he or she could care less, then that means that they do care to some extent.

"I couldn't care less" is the literally correct phrase, but "I could care less" is the sarcastic (verbal irony) form, much like "I should be so lucky."

Both are accepted in use. "I could care less" requires an understanding of verbal irony.

While I and they agree with you that it could be used to impart more sarcasm, Dictionary.com has this to say:

"The expression 'I could not care less' originally meant 'it would be impossible for me to care less than I do because I do not care at all'. It was originally a British saying and came to the US in the 1950s. It is senseless to transform it into the now-common 'I could care less'. If you could care less, that means you care at least a little. The original is quite sarcastic and the other form is clearly nonsense."

I believe in most instances the original meaning is what the speaker intends, but in America the phrase has simply been bastardized.

I agree that most who say "I could care less" don't actually know what they are saying. Still, I continue to use that form when speaking, mainly because it just sounds better in casual conversation.

The dictionary people are right that the original was sarcastic, but they should have picked up on the irony in the newer version. And because it is verbal irony, I would likely use "I could not care less" when writing, especially online.

A possible answer from the website World Wide Worlds writer Michael Quinion:

"There’s a close link between the stress pattern of "I could care less" and the kind that appears in certain sarcastic or self-deprecatory phrases that are associated with the Yiddish heritage and (especially) New York Jewish speech. Perhaps the best known is "I should be so lucky!", in which the real sense is often “I have no hope of being so lucky”, a closely similar stress pattern with the same sarcastic inversion of meaning. There’s no evidence to suggest that "I could care less" came directly from Yiddish, but the similarity is suggestive. There are other American expressions that have a similar sarcastic inversion of apparent sense, such as "Tell me about it!", which usually means “Don’t tell me about it, because I know all about it already”. These may come from similar sources."

I could not care less about this whole thread.
I still have a CAT, but it is 3" high Flow and probably not converting much.
But it keeps my light off.

What size is the pipe 2" or 2 1/4' ?

I could care less about not caring less. But I don't.

My CAT is on, cause Ontario and car laws... ugh... at least they only check under the ricers for infractions since they are drawing so much attention to themselves already.


cmurphy: Right before the split it think its 2 1/4, but the down pipe is 2 1/2.

I just want to say in my state we dont have any emissions checks or anything lik that. The worst thing exhaust wise that happens around here is a cop will pull you over and tell you your exhaust is too loud.
I've never had that happen and ive had some loud cars driving past cops no problems. But I know 2 people that it has happened to, and they were diving extreamly junky cars that were falling apart and the exhaust broke, so in other words cops here dont care if its nice but crap cars can get off the road.

So move to NE if the pooolice is ruining your car modding fun

They just passed a new by law in Edmonton regarding sound levels of exhaust on motorcycles. Its retarded, anything over 95db is considered a noise violation. City transit buses chime in at 98db??? Also they are thinking of adding another section to the bylaw that wouldn't allow the sirens on emergency vehicles to be as loud past a certain time of night. Thats just flat out ridiculous, and quite frankly is just another way for the city of Edmonton to collect money in the form of fines.

So if you ride a piped hog, make sure you make a detour around Edmonton.

95dB is pretty darn loud, but meaningless unless they specify a distance to measure from. For example, our crap heap LeMons race car had to meet a 92dB @50 feet @ WOT specification - and that's for an off-road racing event! Trust me, this car has no mufflers and is LOUD.

Unless you run straight pipes right off the manifold, it isn't that easy to go above 95 dB, measured at a reasonable distance.

Thats what bikers do (run str8 pipes) well most anywayz, and the reason they do it is simple... so other drivers in automobiles are aware of their presence and don't run them over.

Hence the expression "Loud pipes save lives"

Yeah, I agree bikes can go above 95dB with the right pipes. I've always wondered why bikes get the special privilege of being extra loud. Guess Edmonton will be a less popular place with the biker crowd? Drive/ride around...

Really it doesn't hurt my feelings, it just seems unfortunate, because the bike scene is absolutely huge up here. They actually organized a 200 mile run last weekend that passed through Btown here, the whole town was full, and I mean FULL of bikes. It was a charity that raised $230,000+ for cancer research from the rally. They must be aweful people, some1 should fine them for being noisy.

Some were the coolest, oldest, retro bikes you've ever seen, some looked like they were fresh outta Vietnam. They maybe noisy but so is a suped up car, or a loud stereo, a garbage truck, even air shows. Just seems like the Police are shooting fish in a barrel on this issue.

Personally I can take a little noise, if it means seeing something that unique or worth looking at, granted there are exceptions to every rule. But most motor heads keep they bikes happier than their wives.

Well, I go right down the middle with the contraction: "I couldn't care less."
Maybe they'll start teaching this in the schools... Yeah, right - I should live so long!

This.

It's not a T RILEY approved thread.

Well i do have to agree with the law. Getting many tickets for too loud of exhaust. Were i live you can just hit 60mph at my driveway from the stop light. And at 2am when my 3 year old daughter is asleep and 25 stupid hogs go by (you know they all have to ride in groups) and my duaghter wake us up crying cuz they scared here, I have thought about putting speed bumps for them in the road but the township said i would be fined very heavily lol. but what make me even more angry is when there at a 4 way and all 35 go through at once cuz there on bikes. When me and my friends go on cruises we still obay the law as far as 4-ways go.

YO YO YO YO! I have nearly collected all of my new exhaust parts and it's about time to do some cutting and welding.

What the heck should I do with my cat once I extract it? ZZP will give me $50 store credit but can I get more from a scrapper/recycler? What's the going rate? I'd like to have some kind of ball park number that I can negotiate with.

Thank you!

I'd take the $50 credit unless you can find somewhere local that will give you the same. I gave mine (with mainifolds) to Ed Morad for $40 credit about 6 years ago. I didn't have to worry about shipping, so no brainer for me.

What do I compromise if I use an O2 sensor emulator? I think I would like to keep my O2 sensor functioning properly and not deceive the pcm. What's the word on this?

The o2 emulator is for the sensor after the cat. The sensor before the cat would still function as before. Gutting the cat and using the stock o2 sensor after the cat would give you a MIL and a catalytic converter efficiency code. P0340 maybe? Not sure.

Also, gutting a cat for a street car is not legal in all or most states so I only do it as a test. Not as a permanent mod. Usually the test takes really long!

Right. Yes. Simply a test, that's all.


So the 1st O2 sensor affects fuel trim, right? What's the 2nd O2 sensor do that I will be replacing with an emulator?
