Has anyone ever done dual exhaust for a 92 Camaro RS with shorty headers or long headers? I called a few places and was told that if they did the exhaust it would end up hanging real low and I would not have that much ground clearance. Has anyone ever put dual exhaust on a 92 Camaro where it didn't hang real low. I was told they might make a different transmission mount that would allow two pipes instead of just one. Oh yeah, I want true dual exhaust; No y-pipes.

If you want to do a x pipe it will be very low. No matter what it's gonna be low, if you buy a aftermarket crossmember it will help.

I was actually just wanting to run the exhaust to where it comes out right in front of the rear tires.

If you want to get really good ground clearence and arent too worried about the high cost then you can check into oval tubing instead of round. Here is a link to a place that sells it. http://drgas.mybisi.com/

And here is a link to the sticky at the top of the exhaust section that shows dual exhaust setups on thirdgens. https://www.thirdgen.org/forums/exha...l-exhaust.html

Which would be a x pipe, it comes back into a crossover and back out. It needs this for backpressure and will make better power this way and will also not sound like a pulp truck

non stainless oval tubing is reasonably affordable, check into burns stainless' pricing on the stainless to get real sticker shock.

I have duals but they exit out the side. The most tricky part is getting them under the seat pans back to the rear. 2.75s are going to be a real headache. dual 2.5s may fit along the driveshaft/torque arm.

Long tubes will make the pipes hang low with automatic trans/crossmember. On a lowered car you will be restricted where you can take it.

Shorties can be done much easier down stock route..xpipe or h pipe, doesnt matter. Just put it where the cat was/is
2.5" you can tuck up MUCH easier than 3"
I got 3" and could have done better on hanging it higher but its working for now

You can both on the pass side? I was trying to get my 2.75 along there and didn't want to sacrifice that much ground clearance. If you stuck 1 on one side and the other on the other side you should be able to get a good bit more clearance. It's not difficult to get past the auto tranny either:

Any lower and it will scrape:



With some sacrificing of ground clearance one could simply route these pipes backward along the driveshaft:

Besides reducing ground clearance, it is not legal in any of the USA 50-states.

People do get away with it, but doesn't mean they do it legally.

Why do you want to add extra weight to your car? Sounds nice, yes.

Twin_Turbo

iTrader: (25)

if everything had to be legal then half the posts on this forum could go into the trash right away..... is your car 100% legal?

Stephen

iTrader: (12)

Technically no, because my smog pump is off (i do still run a cat & A.I.R. tubes on my exhaust). It was off before I ever bought the car BUT......

My car VERY EASILY passed Smog Tests, when the sniffer was run, on my last smog test.
High Speed-2692rpm
HC 220-standard 4-my reading
CO% 1.20-standard 0-my reading

Idle
HC 220-standard 16-my reading
CO% 1.20-standard 0.01-my reading

I was just passing on info that such a car MAY not even pass at inspection time. Mine shouldn't, but does. I even went out & bought me a smog pump prior to my first inspection, in case I failed.

Don't pass judgement on me, just because I was stating a fact. I only relay information. It is up to the reader to do what they will, to their own car.

my setup hangs a bit lower than I COULD have done with it and I may someday do it over again.
But in short, yes you can fit down stock location and up over the axle.

Come down from the shorties following the stock location. 3" side by side here. 2.5 would be MUCH easier to fit.


Was the y pipe I made for my single 4" but cut it off before the merge and put in the dual exhaust with x pipe


This is the xpipe and flex pipes I used but this is the section that hangs down a touch more than I wanted. Lots of room to hug the floor board here.


Then work your way back under the driveshaft tunnel

I agree with Twin Turbo about being legit. lol

keeslinger31

I hardly think any of our cars are legal in every way, not mine for sure. There is always going to be an exhaust clearance issue with our thirdgens even my single three inch scrapes in driveways and speedbumps so a true dual with longtubes unless your car is jacked up like a 4x4 is going to scrape unless you dont go over awkward inclines but whats the worst that could happen as long as your exhaust is fastened tightly and you dont haul a@# on speed bumps the worst that will happen is your exhaust will get scratched but unless you spend money on stainless steel i wouldn't care. Imo the ideal setup would be shortys with dual 2.5 run along the cat converter area just like stock. looks clean and shouldn't get ripped off lol. oh sh%# speed bump... noticeably louder car goes by...

dquinn

This car is actually not going to be driven on the road. It is only going to be a track car so I don't have to worry about speed bumps, etc.. A few exhaust places made it sound like the exhaust would be a couple inches off of the ground so if there's a way to get more clearance I wanted to know. I am going to take the picture that TwinTurbo posted and bring that to the muffler man. It's ran exactly the way I was hoping to do. Everyone gave some great feedback and I thank you all. I just started with the forum and it's the best. Thank you all again.

I have a 92 Z with dual cat option. Prior owner ran two-2.5" diameter pipes in stock routing. Pipes touch each other especially over rear axle. Orr's exhaust work is nice as he can fit 3" pipes. Just make sure you find somebody that will do a nice job. Mine rattles too much and is annoying at certain rpms.

I found this article about new Hooker longtubes with darkside coating. Towards end of article they show pictures of car underside and also a side profile. Longtubes don't hang down as much as I thought. I also like idea of merging headers together after collectors and running single pipe down stock tunnel.

http://www.dragzine.com/tech-stories...-tube-headers/

I know true duals is enticing but if you size exhaust correctly, single pipe would still work. I bought an aftermarket 700r transmission mount. Haven't installed it yet but I thought that even with these, long tube headers still need to be run under cross member. I'll have to check out the oval tubing. Sounds interesting. You could shrink 2.5" circle pipe to 1.75" tall oval pipe and pickup 0.75" clearance. Yah, more money to spend on my car

i have true duals on my 92 it hangs way to low i have maybe 4 inches but i long tubes with no cats

My dual exhaust install thread:

https://www.thirdgen.org/forums/exha...l-exhaust.html

I modified the kit I got slightly to improve ground clearance, but I didn't lose any ground clearance over the stock setup.

tworley27

there are 4 people where i leave that have true dual exhaust and have no clearance problems. it can be done.

bduffey723

i kno how u feel.

friends call "hey wanna meet at this place?"
me "nope cant make it up the entrance to the parking lot without hittin my exhaust"

watevr i still love the way it looks from the bak since mine just runs straight bak from each header

bduffey723

wait why is it illegal?
im not trying to be an *** just asking bkuz i rlly dnt kno

Reid Fleming

It's one of those weird rules. If an auto manufacture has a car that is single exhaust, the manufacturer can change that to dual exhaust the next year. That is legal. Say GM made 1990 Camaros single exhaust but made the 91 models dual. All is legal.

But if you convert a 1990 that was originally single exhaust to dual exhaust, that is illegal. Never mind that dual exhaust should in theory get better fuel economy.

It's the same way with fuel pressure. GM upped the fuel pressure in Corvettes and F-bodies a quite a few times during the 1980's. Yet putting an AFPR on your car and upping the pressure yourself is "for off road use only."

bduffey723

ya that is wierd. i wonder if cops actually kno that lol

Jesus can't we hav a thread without nay sayers or "not legal" statements?



Yes you can have true duals on your 92. Depends if you want to spend the money and time doing it right to get the best clearance. Going cheap will cause clearance problems which is where most complain about and duals get their reputation.

J91

That's becausethere are certain people on here who continually have to, play cop and let everyone know what is right and wrong! I would say it has do w/ control issues??? Anyways if you want duals do it!

white_formula

Let me kno how it turns out. I'm about to do long tube headers with true duals on my bird.

bduffey723

i have hedman LT's and run true duals straight bak with no cats. i dnt have any clearence issue more than i did b4. obviously speed bumps and such.. one from the bak and from the front. excuse the rust and such. its my 305 DD. sets outside in NW Indiana.

bduffey723

u dnt _need_ an x pipe. juss run it straight back like mine except bend it to where it comes out by the tires. mine stops at the rear end.


and there is no such thing as NOT ENOUGH BACKPRESSURE!

exactly. im tired of all these smog legal posts on here. not everyone lives in Kalifornia...most uf the people on here have probably never had to do any smog tests, or will ever have to.

bduffey723

im suppose to but the ppl tht work there i guess dnt get paid enuff bkuz u hand them a $100 bill and u passed. no questions asked. i dnt even run cats. i had an nx setup. and yet i still passed. LMAO

My dad quoted a guy with an '86 bird with LT headers $900 for 2.5" duals because he didn't want to do it. It can be done and in various different methods, however like people before me have said if you want the most ground clearance you will have to pay for it.

30 of the 50 states require some smog testing, of 1 kind or another. California is merely the most heavily regulated state of the 30 states that require testing.

With California leading the way to stricter requirements, the other states are following. Either setting stricter standards of requiring testing when they didn't before.

It doesn't matter if your tired of them or not. We will continue to mention testing requirements. You can choose to ignore them or let them continue bothering you. Personally? I have enough in my personal life going on to not left some letters on a computer screen bother me.

30 out of 50 states have smog tests but that doesnt always mean everyone in the whole state. Northern VA has smog testing and I highly doubt there will be any smog tests where I live.

Stephen

iTrader: (12)

True about not an entire state. Texas is the biggest state, but not all Texas counties require testing.

But requires can change & counties can change their rules.

Why risk getting tickets or having your car, that have $$$ in to, not being able to be driven unless you dump more $$ into it to replace parts you took off in the first place? Chances are that the people that take them off tossed them & didn't save them "just in case".

Justin89Formy

iTrader: (26)

its a chance that everyone takes when they modify their car. Doesnt mean that they want to have the illegality and risk of it constantly rammed down their throats

Stephen

iTrader: (12)

We aren't ramming it down anyone's throats about it. What we are doing is preventing another reading it, thinking it is perfectly fine to do, getting in trouble with their state for doing it, then coming back & complaining that it "was legal to do".
Yes, I've seen that happen.

Or someone thinking..."Well, I posted about doing it & nobody told me it was illegal to screw the people over at TGO. They shoulda warned me!"

I do admit.....I do kinda find it funny that people get so bent out of shape out of being things are illegal to do. They shoulda known before hand they'd get at least 1 post against doing it, but they get bent when they get posts about it.

Justin89Formy

iTrader: (26)

guess you kinda prove me point in a way that its illegal yet its still done anyway. In my years on this site its typically the new drivers or very young drivers that dont know, or even care to know, the law that whine about it being illegal when they're caught. Pretty much everyone else seems to have an idea what they're doing when they're modifying their cars.

Stephen

iTrader: (12)

I didn't say anything to prove your point.

Yes, people still do illegal stuff & know it.
Yes, we know that.

And yes, we will still tell people it is illegal to do.

What they do after that is their choice

Some states also exempt older cars from emissions inspections since there are very few of them left on the roads. In most states that starts once the car is 25 years old, some states the cutoff is 15 years.

There are other exemptions as well. For example, in PA if you have had your car for at least a year and drive it less than 5k/year you are automatically exempt from emissions inspections.

Also in PA, emissions inspections vary by county. Counties around Philly and Pittsburgh are the only areas that require tailpipe/OBD2 testing. About half the others only have visual inspections, and the other half have no emissions inspections or testing at all.

Here in Florida we don't have inspections at all, since like 2000 I believe.

92RS_Ttop

iTrader: (3)

I forgot to mention Maryland. They are similiar to Florida. In Maryland, you only need to get a car inspected when you first buy it. After that, as long as you don't let the registration lapse you never need to get it inspected again. It almost makes me want to move since I'm only about 2 hours from the Maryland border. I hate having to get my vehicles inspected each year. To me, its a waste of money to pay some guy $50+ just to look at my vehicles and say "Looks like you've got everything taken care of." Then there are the places that just try to screw you any way they can. But I don't want to start in on that discussion, there's enough threads already on here about that.
