I took mine in and got her aligned this morning before i tore up my tires too badly. Then ran her through the touchless car wash to get the lovely green crap off of it I drove through on the way home from school a couple nights ago. A Chem Lawn truck lost part of its load on Southbound I 75 near me the other night and could not avoid driving through the mess on the highway(covered both lanes for about 50-60 feet and was about 2 inches thick,lol)so wanted to get the green tint washed off my ride before it started sprouting grass,lol.

I drove mine today.

Yes, it's a big deal, I'm home for a few days before I go back to Mexico.

Just the usual boring old wash and detail, then a nice drive out in the boonies to blow the carbon out.

Hey GasMan ...do you think they would help the sound on an LS model I mean silent Kinda matches the look but was thinking if there was some way to get just a little rumble out of her would be nice ...

Not Magnaflow bro. Magnaflow exhausts tend to be on the loud side.

IDK man... don't have as much expierence with the exhausts on the HHR. mine is the only one I've heard now that I have it on there.

However, I did hear from somebody before that a SS exhaust on a LT/LS model works well. Bigger pipe and better muffler and all stainless too. Now granted it might be louder if you cut out the resinator in the middle. But I'm not for sure.

I don't think so. Mine is not all that loud, not driving down the road or even inside the shop.

I'm basing that on the vids I've seen of guys w/ the Magnaflow exhaust. The Hahn I have installed is very quiet (the reason I got it, I didn't want "loud and obnoxious") unless you get on it on the highway or something. I'm not knocking Magnaflow at all. It'd be awesome to actually get a vid of both exhausts side by side though, just for comparison's sake.

That would be a good idea. You know anybody with a magnaflow system?

I can't imagine there is much difference between the stock & magnaflow to include another level for the hahn to fit. The magnaflow isn't that loud. I was actually surprised the amount of loudness. It wasn't crazy much louder or even as loud as I thought it would be.
