hello everyone! im new to here aswell as the camaro world. i just bought a 1991 camaro rs with the 3.1 v6. yeah i know its weak and all but for now im just going to enjoy the better gas mileage than i get in my truck. the previous owner removed the smog pump and deleted the cats and muffler and straight piped the car.....but guess what! i need to pass emissions.... so here is the question.

what do i do about getting a smog pump back on it and returning it all to stock including putting cat/cats back on and mufflers and all? where does what go? how many cats does it take?

 

It should take one cat which attaches right after the y-pipe. You can purchase a direct-fit replacement cat for (I believe) around $50-80. These cars have a one-in two-out muffler after the axle. Depending on what the previous owner did to remove it, you could get a replacement muffler or replace the entire cat-back exhaust. I have used dynomax and hooker exhausts in the past and both have worked well.

*I was wrong, it is more expensive than I thought.

 

awesome! thanks for that info. im sure ill end up getting that cat and probably the cheaper cat back system. but maybe replace the muffler with a magnaflow or something. idk yet.

you know anything about the smog/air pump?

 

In terms of the air pump I would just go to a "u-pick" type yard and grab one off a car there.
Honestly when I had the dynomax exhaust on my car it sounded great, I wouldn't bother replacing that muffler with a magnaflow. The thing that I didn't like about the dynomax was that the tips got rusty and after about a year of driving looked terrible.

 

was yours a v8 or v6?

 

Originally, it was a 3.1 V6.

 

was the dynomax on it when it was the 3.1?

 

Yes, I had the dynomax on for about two years, then the hooker on for 1 year. When I did the LS1 swap, I had a custom y-pipe made and reused the Hooker exhaust.

 

awesome thanks for the info!
