Looks good and wasn't too pricey and great pick up, but a little too loud in my opinion.

I had been planning on buying this for my 2006 Grand Prix GXP for awhile now and I'm glad I finally bought it. I had a local shop install it for me since I don't have welding equipment. Sound it deep and rich without being overly loud. Throttle response in conjunction with my air intake is a great improvement over stock.

Rumble

It has a nice rumble to it, but at low speeds/low gear it can have a drone to it.

Wow! I was a little worried at first thinkin that the exhaust would not change too much on the sound or performance. boy was I wrong... as soon as I unpack the box I knew I made the right choice. it look easy to assemble but I paid a local shop 90 dollars to put it on. as soon as I turn the key it put a smile on my face. the sound is perfect not too loud and not too quiet. my v8 actually sounds like a v8 now. the service with auto anything was beyond anything else that companies offer these days

Awesome product! Love it! Sounds just as its described! The installation was very easy, except that I had to buy a new gasket that goes between the cat and the resonator, and some bolts for that also. Other than that, its great!

Now it PURRRRS!!

Had this system installed on my 2006 Grand Prix GXP because it lacked the "rumble" I was hoping for when I bought it. My husband and son had it completed in about 1 hour and 15 minutes (including a coffee break) and said it was incredibly easy! It has a nice tone, not obnoxious at all. After having a ram air hood installed it needed to sound like it looked (like Chip said), and now it does! It is a BEAST! Thank you AA for the fast shipping and great packaging.....and thank you Chip for recommending Magnaflow!

Great looking and sounding system. Installed by my muffler shop in less than an hour. Sounds great. Pleasant deep sound on start up and idle. Nice "rap" on hard takeoff, doesn't sound "ratty" or "raspy" like many systems I've heard. It "purrs" on the highway -- doesn't "drone." I can carry on a normal conversation or listen to the audio system. I bought it for the sound, and not the extra horsepower. Also like the large and well-polished dual tips. Clearly lets an observer know the system is not stock.
