Hey Joe, I am following up on your question about "how my exhaust sounds" now, after hours of running the car and taking it for a long drive today, the glass packs have settled in. I keep thinking I have an exhaust leak, but I know its the glass pack rattle, which I have to roll down my windows when I am backing out of the garage to get the full effect of using glass packs with the stock OEM's. I can pretend I have a race car...How does it sound?

Wow! It's nice to hear stories of good samritans looking out for those that don't have a voice.In the late 70's, I lived in ATL, and had a neighbor in the bldg across the street with a Nova with open headers. every morning at 5:30, he'd start it, and do a burnout to the corner. After a month of that shit, my buddy and I went out one night, and put the rear axle on blocks, so the rear wheels exactly weren't touching the ground. He went out the next morning, and instead of a burnout, sent pieces of the engine to the corner,lol. I could hear applause from both apartment buildings.
He got the idea, after that. I found out later that someone else had added a quart of nitromethane to the gas tank,lol.
Back in my Pontiac days I had to install a Borla cat-back system to get the drone to say goodbye. Now, that WAS a 6.0 liter L76 that was over 350 HP stock in a 2009 G8 GT.What is the reason for replacing the exhaust? If you are looking for a good sound, you pretty much aren’t going to get that out of the 3.8. They just are not a good sounding engine, and with larger exhaust they tend to drone at highway speeds. If you are looking for performance, your money is better spent elsewhere as the 3.8NA will never be a powerhouse, and you would need to be making significantly more power before the stock exhaust really becomes a restriction. If you just want the look of the dual pipes, get a stock rear section off a V8 car in the junkyard, it will bolt right up to the stock front section on your V6.
