Single to dual? how is it done?

I have a singe pipe exhaust on my camaro, but i can pick up both mufflers and pipes for a dual exhuast for kinda cheap right now, im just wondering if it is possible to make the switch and what would i need to make it work?

Most people have a muffler that has one inlet and two outlets. I'd suggest you look into that. Whatever you do with 2 mufflers is going to be very cramped and probably not worth the effort/cost just to have an extra pipe coming out unless you replace the entire exhaust system or the majority of it.

well wim picking the dual up from the junkyard (great place to go) and it comes with the 2 mufflers and tips for 25$$ like my single has that one big round muffler, but all of the duals have the 2 mufflers at the bottom, thats what im getting at, for 25 bucks thats not to bad. im just wondering is there any different pipes that go from my one muffler instead of the 2. on my single the pipes go from the muffler to the rear passengers side tire then to the engine, i just wanna know if the dual is located in the same position

What did this junkyard dual system come off of?

I hate to be a broken record, but if you searched for "dual" on this forum, you'd see several posts on how it can be done. There is a recent post with links to pictures of a few different approaches. In summary, our cars aren't made for this arrangement. Any attempt at it will result in some compromise (ground clearance being the primary victim).

For most street setups, a nice mandrel-bent 3" single pipe system is more than adequate.

alright, i have searched alot for an idea of how to do this, but i couldnt find anything. I really need to get this done soon. So i dont have any emmisions laws cause im up here in canada. So im safe on that side. I know for a fact that they will fit in the stock setup where my single runs right now. but i might need some flex pipe to get the thing attached to the other end of the exhaust. So if anyone has any ideas (cause i have searched) i need some ideas

Have you looked here https://www.thirdgen.org/techbb2/sho...hreadid=204351 ? It's right at the top of this forum.

If you are getting this from a junkyard, then it must fit, right? Or, are you getting this stuff from something other than a 3rd gen?

If it isn't coming off of a 3rd gen, you might as well save your $25. Next to nothing will work, you'll end up buying a bunch of stuff to get any of it to fit. The end result will look crappy, sound crappy, reduce ground clearance, and probably reduce performance.

Besides, the chances of you needing full dual exhaust for performance reasons are next to nil. Most any aftermarket single system (as already described by rezinn) will do just fine.

(BTW, how do you "know for a fact that they will fit in the stock setup where my single runs right now"? If you know that, why are you asking for ideas?)
