hi i have an 82 trans am and the factory exhaust setup on the car blows so i was wandering if it is illegal to have side pipes on a car. it may sound like a dumb question but i heard different things so i just wanted to make sure before i go ahead and do that

89fbirdformula

yes they are illegal, so please for the love of god dont put hillbilly sidepipes on a thirdgen.

well the only reason i was going to do it was because once the exhaust exits the headers and down the car to the tail before it passes the diff it goes straight up and then back down. since the side pipes are illegal then is it possible to fit a true dual set up in a car like mine without too much fabrication needs

technically, thats also illegal. Its not something simple to do, most if not all of it would have to be made from scratch. dynomax has a 3rd gen dual kit, jegs/summit have it, but its not a very well made/fitting setup.

duals have been done, in fact there is a sticky at the top of the exhaust fourm page with info and pictures of dual setups

Isn't this a state-by-state law?

itsMikey

i believe so...

GeneralLC

Here are some laws for Pennsylvania.


175.75. Exhaust systems

(a) Condition of exhaust system. All components of the exhaust system shall be in safe operating condition as described in § 175.80 (relating to inspection procedure).


(b) Exhaust system requirements. A vehicle specified under this subchapter shall be constructed, equipped, maintained and operated to prevent engine exhaust gases from penetrating and collecting in any part of the vehicle occupied by the driver or a passenger, in addition to requirements of this title for an emission control system and smoke control for a diesel-powered vehicle.


(1) A vehicle specified under this subchapter shall be equipped with a muffler or other effective noise-suppressing system in good working order and in constant operation. A muffler or exhaust system may not be equipped with a cutout, bypass or similar device and a muffler may not show evidence of external repair.


(2) The exhaust system of a vehicle may not be modified in a manner which will amplify or increase noise emitted by the motor of a vehicle above the maximum level permitted by Chapter 157 (relating to established sound levels).


(3) Headers and side exhaust are permitted if the vehicle meets the requirements of this section.


(4) An exposed exhaust system shall be equipped with an adequate heat shield or protective system.


(5) An exhaust system shall extend and discharge completely to the outside edge of the vehicle body, including a truck bed, or as originally designed.


(6) A firefighting vehicle is exempt from regulations concerning exhaust systems, mufflers and noise control.


Personally, I'd ignore people like 89fbirdformula. People like that are just close-minded.....Well, I'd like to say something else, but it's not nessesary.

ok i thank you all for the help and tips lol

In general they must run to the rear axle and can dump before or after it.

problem is the poisons in exhaust gasses build up in your system over time so it won't kill right away. So if your smelling anything check door seals or rust holes in the rear section.

Mine run's all the way out the back but a rust hole behind the tail lights would suck it in with the windows down.

Myself I found the 90* turn out for a side pipe on mine killed the upper RPM band and had to knock a hole in the end of the pipe so it could blow out straight and the side.

Got sick of the noise and run it out the back now, let the person behind me hear it.

please for the love of god, dont put side exhaust exhaust on a 3rdgen!

no one asked your opinion, so quit posting it.

89fbirdformula

thats the beauty of an open forum...it goes 2 ways player.

Hopefully the OP gets his head on right, and gets a REAL exhaust.

Dear "player",

Learn some respect. He didn't ask your opinion on if it looked good on HIS car. It is HIS car, HE can do what HE wants to it. So get lost.

89fbirdformula

respect? seriously?

there is a reason there is a DUAL EXHAUST sticky, and not a "hillrod sidepipes" sticky on these forums..

I'll do my damndest to try and convince him to spend the $$ and go duals instead of sidepipes.

Having said that, you can blow me.

Nice attitude. We can all see how classy you are, now.

What kind of jerk goes into people's threads and pisses all over them? You, I guess.

89fbirdformula

oh yes, my reputation is now tarnished because i told you to blow me.. so be it.

im not pissing all over his thread, trying to help him from making a BAD decision.

tekkitan

iTrader: (1)

You are though. He wants side pipes. It is only a bad decision in YOUR opinion. If he likes it, he can do it. Just because someone had side pipes does not make them any lower than you. Maybe one day you will grow up and realize that.

89fbirdformula

did i say it makes him any lower then me? NO.

i have NEVER seen a set of sidepipes on these cars that looked anywhere near "classy" or well thought out..

dual exhaust is just the better route to go, for many reasons.

side note, if his car is as stock as his profile claims, theres really no reason for either mod, a simple catback will more then get the job done.

I like the clean and simple look, as do the majority of the members here, i am guessing he is young, with little experience with cars...showing him the grass is greener on the other side, there is no harm in that, you seem to be the only one with the problem.

I'm not the only one that spoke against you in this thread.

So calling side pipes hilljack or whatever you chose to call them, that isn't you talking down to people who think they look good? You need to rethink what you say before you try and defend yourself, because you are full of contradiction. This is my last post in reply to you in this thread. I'm not contributing to you ruining the OPs thread or putting down his opinion any more.

89fbirdformula and tekkitan please be friends now
No need of throwing **** at each other.

The taste is like your buttom.. splittet..


You can always post and give advice, thoughts , and tips and trix.
But we can be civilizised and not call each other names and fight over it.

If someone really wants sidepipes, let them get it.
Give him suggestions and explain bad/good things about the thoghts.

Dont shot it down right away, give him/her time to think about all informations etc.

and again, dont take this post the wrong way, I just hate seeing fights in such a good forum as this is

PS. Im getting the Hooker 2055 Coated, and Borla #14888 3" all the way this winter. seems like an awesome setup with a new Magnaflow 3" cat to, hopefully it will get an increasement .DS

i still havnt mad a desision on the side pipes the exhaust will come later but if i do the math and on cost performance on both and find out that the one is better i will go for it im trying to find out right now whats illegal or not so i dont go waisting my time on pointless research. id like true duals but i will have to put out a lot of monney for them and haveing the rear axle in the way might pose problems but if you say side pipes are bad i would like to know as to why they are bad and the car isnt stay stock so im not getting a catback just because it "sounds" good for $1000 when id rather performance but id rather you not say anything bad against my opinion for you dont have to even see them, thank you.

When I bought my car, it was open header. I decided to go with the side exit, but I went with tips that I feel match the lines of the car... Here's the thread on here when I posted a vid of the look / sound.
