Exhausted HHR
I have been working on cars and racing them for almost 35 years, and have done both total exhaust (headers back) and simple muffler changes. My first thoughts were that with a 2 1/4 exhaust, you wont gain much from a cat back over a muffler change. The chain is only as strong as the weakest link theory-if the pipes in front of the cat are 2 1/4 and you still use the original restrictive cat, changing the muffler should be adequate. But, then I realized that the same diameter pipe that is bent better would reduce back pressure. So, if changing the muffler to reduce back pressure is good, then getting rid of sharply bent pipes will be even better.
If you take a garden hose with one kink in it the water runs slow. But the same hose with more kinks in it will run even slower.

Couldnt resist, with all the "High performance" HHR, its getting pretty deep in here.
A mechanic, a seasoned racer, a dumb *****, and an aftermarket HHR parts dealer walk into a bar...stop me if youve heard this one...
