Colorado exhaust law?
I just had a Magnaflow installed on my 00 Taco. I had them put a turn-down right before the rear axle. Someone on the forum mentioned this was illegal in some states (something about the tailpipe having to come past the rear axle and shoot out the side). Anyone know if a turn-down before the rear axle is legal here in Colorado?
I have a few friends that have this type of exhaust around here, so I am not sure. They havent gotten any flak for it as far as I know.

The exhaust must exit behind the rear axle if it did so from the factory but then again you're getting this answer from somebody who ran a straight pipe in their Eclipse for 7 years and just swapped a cat in to pass emissions.

In all honesty, I don't think it will be a problem unless your exhaust is REALLY loud and the cop wants to nickel and dime you. I think the law is in place to minimize the chances of exhaust fumes seeping in through the floor during idle, which could expose you and your passengers to carbon monoxide.
My other concern, as mentioned in your other thread, was with smog stations. Most just plug into the OBD port and check for a check engine light. However, I have had to go on the roller once here in my Civic. They also have probes they stick in your exhaust, and if nothing is coming out (since you left the stock section in) they are gonna be suspicious.
If you really wanted to, you could just drive down to a smog check station and ask one of them. I doubt they will remember you in the future.

In Colorado, my impression thus far, is that if it has an engine, tires and a headlight, it is street legal.
I really doubt you will get nailed for this, if it is even illegal at all.

Thanks for the posts especially the last one straight from State. I'm actually going to agree on this one. My buddy who lives here in Boulder took three post-82 cars in for emissions tests all which had the cats cut off. Can you believe that? ALL three of the vehicles didn't have cats and were passed by the emissions peeps! I think you're right... if it has "wheels or tits you're gonna have problems".... oh wait... wrong quote.... "if it has an engine, tires and a headlight, it is street legal"
Thanks again!

I have never had to sweat emmissions, but I have pulled up to gas stations in Buena Vista and Grand Junction where I was fueling next to tube buggies that just drove in and drove out on the road.

We've got an old scout, and when my bro ripped the exhaust pipes off at Wheeler lake, we ran them out the sides, in front of the rear axle. Got pulled over with no problem. Also, i've seen old fords, and some muscle cars around here with pipes in front of the axle. As for being under the car, you've got a taco, so your pipe is coming out under the bed anyway, not the cab, so fumes shouldn't be a problem
