Ok heres the question...kinda complicated. I am putting a 350 carbed into my 91rs...and im in cali. So im completely not smog legal anymore...i have a way around that. So i can get the car smogged even with the carb. Now my dilemna is with exhaust. I really really want to do true dual that exits before the rear wheel. Now i know this is not legal at all...but i figure since the car already isnt legal i might as well go all out. But im worried about getting hassled. I know its not too often a cop will open your hood to see the carb...so im not worried about that...but what do you think about having true duals with no cats that exit before the rear wheel. Do you think that will attract too much attention...and will cops get down and look to see if there are cats or not? I know its a huge fine for not having cats. So i guess my question is this. Has anyone gone this route in a smog controlled area? How much of a problem was it for you? Should i go all out and go true duals since it wont pass smog legally anyways...or should i play it safe and get aftermarket with cats even though its carbed?

 

put fake cats on at the very least.

You mean like gutted cats? Ok...that makes sense. Im guessing i could just pick up some junkyard cats for it. What about the fact that its true dual? Since it doesnt come like that from factory doesnt that in itself make it illegal? Do you think theyll hassle me if its true dual but looks like it has cats? Thanks though for that tip...i didnt even think of that and that makes a lot of sense. Now its just convincing the muffler shop to do that considering probably the only way i can get them to do it is to tell them its a non-street car...and well, i dont know why youd want gutted cats on a race-only car...lol. Hmm...ill have to think about that one.

 

are you trying to get in trouble? Or are you really that clueless about it? If a cop sees the duals that exit before the rear wheels you better believe he will see what else he can find that isnt smog legal. So now, he will open the hood, GASP! see the carb and Josh gets a big fat ticket and probably some kind of oversight to make sure he gets that pretty 91 camaro fixed in accordance w/ state law.

If you leave the custom exhaust alone, or have it in a stock location, exiting where it should, you will appear to be a law abiding citizen w/ an exhaust a bit too loud. That will make officer Bob smile as he remembers his own youth, as he keeps on driving away from you. Thats how l would go.

But, do as you wish.

I agree... it'd be better to just have rear exit exhaust...

Or maybe you could rig something up where you have pipes out the side and rear, and a remote baffle to control the flow... open pipes out the side, cats and Dynomax out the back... that way when he pulls you over, tell him it's a strip car that needs to be driven to the track, and you wanted to make it street legal for that, hence the need for the baffle and 4 pipes... Make sure it's operational so he can feel for the flow...


Or maybe this doesn't cut it... I don't have gay Cali laws so I don't know

Otherwise, just use hi flow cats and Dynomax out the back, it seems like your best bet.

Removed air baffles, mandrel bent cat-back pipes (but stock replacment muffler, Dynomax Turbo is on the way)

Maintenance since I bought it:

I'm pretty sure the cop isn't going to have every cars exhaust system memorized. As long as you have an exhaust system that looks reasonable, and a "cat" for each pipe, he's not going to know that it didn't come dual from the factory.
I'm pretty sure that as long as you can pass smog, the cop isn't going to strip search your car.

No guts, no glory.

 

...unless you own a 1970 AAR Cuda or Challenger T/A, the only cars that have exhausts that exit in front of the rear wheels are those with side pipes...

...as far a passing a smog check, he probably won't if he has to meet 1991 guideines.

...I'd do a little more checking into exactly what your looking at if you get busted before I just arbitrarily did it...you could end up facing a fine and having to get you're car into compliance again...

...bottom line...how deep are your pockets...

 

are cops really that bad? I kinda new they were that bad in CA. but are they that bad in the rest of the country?

 

...it's not that they're "that bad", it's just if you "flaunt" what's clearly a violation in their face, they're more likely to look deeper for more subtle ones. Some of the New England states are really strict with car mods...down here in Florida they really don't hassle you unless you have a flagrant violation or are stopped at a safety checkpoint, which they randomly do from time to time...

 

You could try and convince him that it's a 67' stingray with sidepipes, but that probably won't work. I'd agree that true dual running out the back won't be asking for too much trouble. Many people have done it on this board so look around. Good luck with whatever you choose to do.

 

Well i wasnt clueless on the topic. That why i asked the question...if i was clueless i wouldve just gone and done it. I think ill probably just go with the true dual, gutted cats out the back...so it at least looks legit. Although i dont think too many cops would do anything in my town (theyre pretty leniant in pleasanton...especially with so many carshows at the fairgrounds in town) but i still dont think i can afford to take the chance. Although i really wanted that unique look...But hey...cant go attracting attention to a non-street legal car more then it already does i guess. Thanks for the input guys...Although i did get trashed on a little...i did get some good info...especially about gutted cats...i never even thought of doing that...sheesh.

 

A gutted cat will pose as much restriction(or more) as a properly functioning hi-flow cat. If you really insist on going cat-less, insert a straight-pipe through the cat.

 

Thanks for the info. I kinda thought thats what you did when you gutted the cat was cut out all the crap and insert a pipe in there...do some people just gut it and leave it open?

 

ya some people just smash out the insides. I have a new catco cat for my headers and I could easily slide a 3" pipe all the way through if the ceramic brick wasn't in there. If my exaust isn't loud enough I'll probably do that

My question is why you want to go carb? Unless you are making gobs of power the stock routing does quite well. What are the mods going to be?

The engine were building is projected to have about 485 hp at the crank. I went carb cause i didnt have enough money to go with aftermarket FI like superram or anything...and my computer was shot so even if i wanted to use the TBI which i dont think could feed that power...and if it could would definitely restrict it...it was still gonna be too much money that way. So thats why i went carb.
