My HHR engine sounds crazy loud
When I drive, the engine sounds really loud. Like a car that doesn’t have a muffler but the sound is coming from the engine. It drives ok, but the noise level is crazy. Where do I start troubleshooting?

I prefer to simply replace the complete down pipe, a little more but just the three exhaust nets at the manifold and the two bolts at the flange.

To replace just the flex pipe, yes then cut the broken part off and weld or clamp in a new one.

They might, they might not, I just wanted to convey there are more ways to fix a flex pipe.

My flexpipe has failed and I didn't really feel like fixing it myself, but once the exhaust shop quoted me $250 today and talked to me like I was an idiot, I came home and ordered the part to fix it myself. I guess I'll be firing up the welder next week. Best part is that it was $40 on Amazon, but I had points so it only cost me $21 shipped
Funny thing is that I'll pull a tranny out of one of my perfectly running old classics, just because I want to paint it, but when it comes to my daily drivers (like the HHR), I don't even like to change my own oil
