So, for a normally aspirated LSx what would be the quietest muffler (or combination of mufflers or mufflers/resonators) one might use w/o hurting performance. Keeping in mind the need to keep the size somewhat reasonable.

I have always been a flowmaster fan. BBC, SBC, LSx, I have had them on everything and guess I always will. The goat has them and so does my malibu. Heck, the GTO is in some of flowmasters advertising now (High Performance Pontiac), so I guess I am a bit jaded. I think it just comes down to personal taste, buy what sounds good to you. :thumbsup:
