Yeah it can be kinda funny to hang just a muffler off of the stock HHR and have it do nothing till the 3,000 rpm range kicks in! Since you know what you have maybe do the Magnaflow Muffler with Chrome Tip and some dyna mat to lessen the in cabin noise! Just remember you'll be silent when you step on it without the tune!

Best-O-Luck ,

 

found this one inspirational

 

Now that would be sweet! I think anyone with that kind of exhaust better have something to back up the looks. Hmmm, LS7 swap anyone?

 

I would humbly submit 300+hp backs it up fine in an HHR

 

love my Dynomax muffler

 

I went with the Imco T-910 muffler sounds goodn to me, I like it.

 

i just put on flowmaster force2 system its perfect not to loud judt right. now im waiting on my airaid and my jet performance 2 modual .i moved the flow master tip out as far as i could i had it push all the way forward moving it back made a big differant love cant wait to see how cold air intake abd stage 2 work out

Cat Man- That would be just fine! Heck, any small black would be sweet.

 

OK so this isn't a V8 but I like the chopped top:
