I've got dual outlets on mine.
The main problem is routing the pipes. Not much protectiojn from heat for the gas tank. California cruisers is the only one I know of the sold a dual set-up, though you may be able to get it done by others since they used to have decent pics of the underside showing the routing.
On mine we took a Y pipe from right behind where the resonator was on shot a pipe to each side in front of the rear wheels. Did have clearance issues. Had to change to springs with less drop than the 1st gen GoldLines I had.
Basically we did a custom cat-back. Sounds great and I did notice a small increase in power and a big difference in sound.
It's been tweeked some since it was installed but here's the original thread on mine. https://www.chevyhhr.net/forums/show...hlight=exhaust

I saw one photo on the internet of someone who did "duals" on his/her HHR. They just 90 degree tee'd off the side of the tailpipe behind the muffler, went straight across behind the bumper cover, and added another matching chrome tip on the right. Looked like they trimmed the bumper cover to match the left side. The bigger chrome tip hid the tee intersection pretty well. I don't think it did anything at all other than look cool. May add a little more sound like a megaphone tip, but I expect very little. At least in the winter you'd probably get some smoke out of both tips. :-) I hope this helps. God Bless, Marc

Camaro Style Muffler
Not sure there is enough room between what looks like a resonator and the rear beam for a Camaro style muffler, unless it was very small. Did this on my GMC Sonoma V6 but there was plenty of room.
