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!

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:cowboy:
