Good to know. What helped you come to that conclusion? Did you try something?

On my 2001 Grand Prix GTP, I had SLP headers and the SLP exhaust system. No resonator and it droned badly at highway speed. It got on my nerves. Didn't sound that good either. In my opinion, a 6 cylinder will never sound as good as a V8. Having said that, I would like to hear a Corsa system on a w-body. Bet it sounds the best you are going to get.

If anyone knows of any reasonable way to make the 3.6 LFX rumble a bit without droning on the highway that'd be great info to know. It still bothers me that the exhaust makes 0 sound when I'm driving. To be fair I have unreasonable expectations as I spent the 3 years previous to my impala driving around a '93 Dodge Stealth R/T which made some fun noises That car sounded great, and it was just a 3.0 V6.

The Corsa system is going to be it. I have it on my GTO and you can barely tell it is there at highway speed. I have not heard one on a 6 cylinder W-body but I am willing to bet it sounds good. Corsa makes a very high quality, zero drone system... hence the higher cost of admission. I do not know if there is a Corsa system available for the 2006 up Impala but I bet the Grand Prix system can be made to work if there isn't one.
