If i delete my cat will that make the exhaust louder? I dont have to worry about state emissions since i live in Alabama. Thanks Matt

FYI....You may not have emissions inspections, but removing a cat is still illegal, regardless.....Federal law (which overrides state law, requires the cat.

With that said.......Yes. Your car will be louder. Not necessarily any faster, but louder. Like a r i c e r...loud does not equal fast.

With all the fast (and/or loud) cars these days that DO have cats, why do you feel the need to remove yours? Yours can be loud, fast and still be legal.

removing the cat is very illegal as said above. It also makes the exhaust smell horrible and will give you headaches. This issues usually arises when your gf gets in the car and is annoyed. (been there)


then theres another issue...

horsepower makes noise---noise doesnt make horsepower

check your local laws, my car will soon be registered as historic and it doesn't have/need cats. If it were registered normally it must have a cat (because it originally came with one)

Ok thanks and on another note I DID NOT ASK IF IT WOULD MAKE IT FASTER OR IF IT WAS ILLEGAL OR IF IT WOULD SMELL FUNNY OR IF MY 2ND GRADE TEACHER WOULD LIKE ME DOING THIS OR IF GARFIELD IS FUNNY OR IF I LIKE HAMBURGERS ECT ECT ECT!!!!!!!!!!!!!!!!!!!!!! This board is about on my nerves all i asked if it would make the car louder....thats it !! R I C E R THIS R I C E R THAT ***** THIS ***** THAT!!!! Last time i checked i drove a CHEVROLET. Not a Honda. Thank you very much.

Check into driving limits on Classic Car registration.....Here is TX, you are limited on how much & when. It can't be a daily driver, or even just occasionally to/from work.

Curb your attitude, teenage newbie. If people get on your nerves giving you honest advice...LEAVE.

well said

Teenager? Im 31. Im not the one with the attitude here i just wanted to know one thing will this make it louder.Thats it. I didnt want to be judged for cutting the cat of my car. Sheesh.

We gave you advice.....I even gave you your answer THEN added..."With that being said....".

Nobody judged you on your choice to make your car illegal. Just informed you. Just don't come back here on TGO crying that you failed inspection, or for a big fine, for tampering with federal emissions parts.

Look in a cat canverter, see all that honeycomb tube like stuff? That has to make it quieter, even if its high flow i would think that it still muffles the sound.

Sure acted like a Teenager... Jeesh. and yeah, that was a pretty uncalled for explosion of astricks...


Yeah, it'll sound louder... and resemble a Blender eating Iron chains... Sounds bad without a cat, unless you've got a good Muffler.

Get yourself a Flowmaster Super 40 Single exit. I have one, WITH a cat, and it is LOUD. In fact 90% of the time I wish I didn't have it it's so loud, my car is a daily driver.

Blender eating chains?? Do you mean it sounds tinny? I have a magnaflow 16829 cat back, so no cat would still sound good, but a cat will sound better?

[quote=Tice;4050897]Sure acted like a Teenager... Jeesh. and yeah, that was a pretty uncalled for explosion of astricks...

I acted like a teenager ? I did? Come on... you guys called me a r i c e r for wanting to cut my cat off. You dont think thats a little harsh? A wee bit extreme?
I would like to know how many R I C E R S are on this board since the definition is having your cat cut off. So if you have no cat on your car sound off, lets here from the r i c e r s on here!!
I dont understand why people on here cant just answer a simple question without starting a bunch of bickering. My post before this one wound up being a fighting match between two members. What im saying is why can't we all just get along instead of flinging darts at each over a simple car question. My thanks to those who answered my question with out flinging darts.My hats off to you.
Matt

That was rather rude. The advice that was being given was not an answer to the question at hand. I find that most of the illegal stuff is done by older ones with more money.

At 65 I'm still ripping off junk that I don't want or need. Besides, you're only 6 years older than that "teenager".

[quote=redfbody;4051196]I have a true dual exhaust and no cats with moroso sprial mufflers. My exhaust sounds perfectly fine to me. Sure dosent sound like i have chains in a blender under my car. I think a R I C E R is someone with 17" + bling wheels and a loud sound system so everyones opinion is different. Some people think there god on here and if your against there opinion then your a moron. I just think they need to remove the stick out of there @ss.

My 87 runs Hooker 2210 into a Mufflex Y pipe into 4 inch exhaust with no cat into a Spintech dual out muffler. It is very very loud and sounds really good. I don't have any ping or tinning noise at all. I don't care about federal emissions and 95% of inspection stations overlook the no cat anyway because of the year. I think you will be impressed providing you have a good flowing muffler.

Fortunately or unfortunately you always get more info or advice than what you ask for, goes with the territory. Sometimes just wording your question makes a big difference and regardless there are always guys ready to try to beat you down anyways. Later.

I've got a high flow cat, flow master muffler, and headers on my 350. It sounds really good nice deep tone. It had no cat when I got it and the sound was just more high pitched. In my opinion cars sound much better with a cat.

About the Chain in blender thing, Don't forget to read the rest of my post... Particularly the part about 'unless you've got a GOOD MUFFLER'...
Ultimately, I think the OP got his answer. Really, it depends on the muffler. Cat or no cat, it comes down to your muffler, and size of pipes that make up the sound aspect of a set up, to my knowledge.
btw... Nobody called you a r i c e r... Stephen mentioned that they like to cut cats off, but never called you one, or compared you to one... you brought that upon yourself.

Hey guys thanks for the info. I do have a flowmaster with 3" pipe from the y pipe back already. Oh yeah its a 305 tpi.

Same setup as my dads' Bird, Oughta sound B!tch!n'.

I just put my exhaust on my Formula yesterday. Did headers, 2 1/2 inch y pipe into a 2 1/2 intermediate pipe with no cat and a Flowmaster 80 series. I think it sounds awesome.

What headers?

I had no choice but to remove mine when it broke and got wedged into the exhaust. But even with the stock muffler on a 305 carbed, it did not have any kind of high or tin sound to it, was pure low. Now same setup but with an Imco turbo muffler instead, sounds like a muscle car. I would and plan to replace the cat sometime when I have money, but for now, front/rear main seal comes first.

As moderators and members of thirdgen.org we feel its our responsibility to teach people to keep their car street-legal. So any discussions about removing cats or other federal-required emissions parts are going to include talk about how its illegal to remove them. Otherwise, the board could get in trouble for advocating illegal behaviour. Dont laugh, more stupid things have happened. Sally Soccer-Mom behind you smells your car with no cat and complains to her local politician that its ruining her precious Buffy or Tayler's lungs.

Now, with the recent change in presidents, several pieces of legistation have been suggested by members of Congress that will either scrap old cars, or force older cars in all states to have to pass an emissions test. None of us wants to have to go thru California-style emissions tests, right? I do every two years and its a pain in the butt, but my car passes every time because I built it right, and I keep all the emissions parts on it. But mark my words, there will come a time in the future where every state will have to do emissions testing on all cars, all in the name of "global warming" or other crap, and you guys who have removed and trashed your parts will be paying a pretty penny to buy used ones again.

Bottom line, keep your emissions parts on your car and do us all a favor. We hot rodders already get a bad name from the people street racing. We dont need it to get any worse with the smog police.

Get some racing seats too.
Yes it will be louder and will have that tinny and edgy sound.
I am ordering a new system for mine and it that is the way it sounds I am going to install another muffler where the cat goes (removed by previouse owner).

Don't forget those racing seats! They are a great compliment to cheap noise and an attitude. I love your car just not your taste.

Removing the cat dosent make a tinny sound. Get your facts straight before you open your mouth ya tool.

Are you talking??

Kevin, well said. Later.

It's very unfortunate though...Frikkin Gov't

Same thing i heard, what catback you running? mine's in sig.

Or are you running long tubes?

yes your car will be louder, point made, but i do want to let you if there not enough back pressure as well you will lose or even cutting the cat of reguardless you will a lil fuel milage. just lettin ya know if you milage is an issue for you. I have a flowmaster 50 on a single system without a cat and its loud as crap. lol a.k.a. maybe WAYYY to loud lol. But on a third gen all i have heard from friends is that they maybe lost 1 mile to the gallon, but it helped performance just a little.

Well, the moderators at TGO need to get busy. Doing any of the following is as illegal as removing a cat.

* Removing the EGR valve or plugging its vacuum lines
* Removing or disconnecting the PCV valve
* Removing the stock air cleaner and heat riser duct plumbing
* Removing the catalytic converter
* Removing or disconnecting the air pump
* Removing or modifying the stock distributor vacuum advance/retard
* Altering the stock ignition advance mechanism or timing curve
* Replacing the stock distributor with an aftermarket unit that is not emissions certified
* Modifying, removing or replacing the stock computer or PROM chip with a non-certified component
* Blocking the heat riser duct under the intake manifold
* Knocking out the filler restrictor on the fuel tank inlet pipe
* Replacing the stock non-vented gas cap with a vented cap
* Removing or disconnecting the fuel vapor recovery canister
* Changing the idle mixture or stock carburetor jetting
* Removing or modifying the carburetor choke
* Modifying or replacing the carburetor accelerator pump with non-certified components
* Installing an intake manifold or racing manifold that lacks provisions for the stock EGR valve and/or a heat riser duct
* Installing a carburetor that lacks the stock emission hookups
* Installing non-certified fuel injectors
* Installing a long duration "racing" cam that is not emissions-certified
* Installing exhaust headers that lack provisions for a heat riser valve, an air cleaner preheat stove or fittings for an oxygen sensor (if required)
* Installing valve covers with open breathers or no fittings for a PCV valve
* Installing any induction, fuel or ignition system component that is NOT emissions legal

You know what they say about people who live in glass houses.

No cat back true dual exhaust. Hedman 1-5/8 headers to moroso spiral mufflers and dumps @ the front of the rear tires.

Not to mention that the mention that 90% of all roads are posted at either 55 or 65 mph with some minor exceptions and there is a Theoretical and Street Racing forum.. At least with engine and exhaust mods you don't risk the chance of doing 155 mph and killing thrill seakers.

hate too tell you but back pressure isnt your friend the less you have the more power you make. Thats exactly why upgrading your exhaust system increases power and fuel economy less restriction.

I'm not sure why you bolded some of those but not others, but the only ones I'm guilty of is modifying the PROM chip and using a bigger camshaft. I have not removed anything nor have I disabled anything. The bigger camshaft still passes smog, and modifying the prom chip allows me to make cleaner emissions numbers and get better gas mileage.

I think the point is that one of the listed violations is no worse than the next. The Cat removal preaching gets old everytime the question is brought up. I am sure that a properly tuned car with an aftermarket cat without air would run cleaner than the factory set up, however as everyone already knows this is illegal. (especially in CA)

I for one could care less if someone wanted to paint their car pink with purple polka dots and run staight pipes out of the hood. I wouldn't nessesarily encourage it , but I would not be-little someone for doing it.

When I get pulled over by a sheriff or a city police officer I am so happy its not a DOT officer because they will get the inspection mirror out and ask you to open the hood. My old 83 z28 had about all those things on the list and I was pulled over by a GA DOT officer and I had two 10lb bottles of nitrous in plain sight and he asked me to open my hood and started poking around, luckily I am a FL resident with FL tags and its legal to have nitrous in your car and if its over 20 years old you can modify everything so I was lucky.

To the OP:
Nobody called you a r i c e r for removing the cat. You need a little thicker skin (especially if you're 31 years old). This is the internet, not a face-to-face conversation. We don't know you, so we can't possibly attack you personally.

To everyone:
The information you receive on TGO will not always be what you want to hear. But, you will get usable information.

That being said, there are a lot of people in our society today who don't like the free flow of information on the internet. They are more than willing to use things such as any hint of promoting illegal activity to shut down a site. So, while you might get an answer to your question, at least for the sake of keeping TGO in operation you should be tolerant of a caveat that says, "Yes, doing (xxx) will produce (yyy) results, but it is illegal to do (xxx)."

Fair enough?

And, for the record, my Flowmaster 80 series was louder without a cat. Whether you would consider an 80 series a "good muffler" - well, that's a different topic entirely.

This is why you get the BIG $$$!

Changing parts is completely different than removing or disabling parts. Technically you're right, but I dont have a problem until you start removing parts. The cats, the air tubes, the EGR, and the charcoal canister are the most visable and do the most work in cleaning up the air. And those are the ones people will notice that you have removed.

Since you have a problem with everything why dont you get you get a job at an inspection station and preach to everyone there. I think the posters question has been answered and its time to take opinions else where.

This isn't opinion, it's providing information.

Yes, the OP's question was answered. But, that doesn't mean that is all that should be said.

The cat is one of the most effective exhaust cleaning components on our cars. It is also, as Kevin stated, one of the easiest to detect and has the most negative effects if tampered with.

No need to preach at the inspection station - you've got a captive audience there.

Your not wanting to hear something is no reason for not saying it.

I respect everyones opinoins to a point. I understand the pros and cons of this issue and i believe the op does also. The OP got everyones opinion the first time. To keep preaching about your opinion is where i draw the line and it becomes a stupid internet debate in which the person the wins is the last person that posts and having a MOD doing it is just ret@rded (kevin). 57 i think you have sumed up everything well and im leaving this discuss at that.

Im sorry i started this thread. Mods please except my apologies.

Who is monitoring all the forums on the internet to look for any "illegal" activity?
How would TGO get "shut down"?

Im a member on hardcoresledder.com and so is IHI with the red firebird doing a wheelie in his sig, they talk obout everything on that site, even unregstered illegal firearms, and nothing has happened, so how could anything happen?
