Nah, rather stock IIRC. Said the coils couldn't handle the downtown area and had kids, I worked out a sweet deal with him drove down there and did the swap in his complex parking lot last September.

i will get a sound clip/vid of it next the local with it stops in...he has the 3" offroad downpipe and 3"catback with no resonator, it's pretty loud, but has a really awesome tone to it.

Ok cool, thanks! I would prolly keep the the resonator and muffler to keep it sound down, catless is next on the list before exhaust now

My CGS muffler sounds pretty good. It was the only brand I could find that actually dyno'd for a gain on their testing with the muffler for the HHR SS at the time. They showed a 10hp gain

Yea im doing a muffler delete saturday, and getting zzps Catless DP soon, since are exhaust is already a good setup. If I dont like the sound I will get ZZPS exhaust with a res, and muffler, or a muffler like you did.

Tonight, or at the very least before Monday, I will be installing my ZZP Catless DP and catback with resonator and muffler. I will try to get vids but it started snowing so I don't know how well that'll work.

SS fan

Welcome to the site Goatah. What are you installing that dp on ? Snow, not in Calgary ?? Post a pic when you get out from under there.
