Hi,

This is my first post on here. I bought a 2009, 5-speed HHR LT back in October as my first car. Absolutely love driving it, but I think its time to start modding the car.

After reading some threads on here, I'm confident on going with a resonator delete and maybe take out my 2nd cat. As for the muffle I can see that a preferred choice here is Magnaflow. So I'm just curious if a Thrush exhaust would be okay too on the HHR. Does anyone have experience with Thrush mufflers? or videos on how they sound on a HHR?

hey fellow Ontarian, I have not see any videos for Thrush but maybe try youtube, I tried the magnaflow , and did not like it, just personal guess, went muffler delete to pingy,this summer I am planning to try a Porter or smitty's round muffler in place of the resonator and delete the stock muffler, and I hope that will be that, maybee we will see you in Paris on a carshow Saturday night this summer

That sounds great, tell me how that goes. I'm doing the resonator delete soon, just wanted to know if there would be a good muffler that would compliment that. And this car show in Paris, never heard of it but now I'm extremely interested. When does this car show usually happen?

Theres lots of shows come springtime.
I dont recommend the resonator delete, sounds high pitched, raspy and 'rice', and the resonator is straight through and not restrictive anyways so performance wont change.
I liked the sound much better using a stock cobalt ss/sc catback with a much longer resonator, larger piping, and higher flow muffler. Needs some slight modification to fit the hhr, but lots of used ones around for cheap.

If you lose your resonator, you're HHR is going to sound a lot like a racer boy, import fartcan car

Personally, I would never do that with any car that doesn't have a V-8.

I actually put a split-duals exhaust on my HHR last spring. I did it with two OEM straight through type of mufflers and even with the stock resonator, I thought it sounded to much like an import P.O.S.

To rectify that, I actually found and installed a much longer resonator. It actually helped some, but I'm still not 100% happy with it. You lose no performance with your resonator, so I would just leave it alone.
