Well I am going to try and make the LS sound good and not loose any horsepower but maybe even gain some? Well I am thinking about purchasing a Magnaflow Muffler here: http://www.summitracing.com/parts/mpe-12468?seid=srese1&gclid=CP60veeAp7sCFahDMgodWmgAAQ
What do you guys think and what are you running? Also will switching just the mufflers out help out a lot for the desired growl?
