I can't speak to the muffler alone, but the full Borla systems do not drone. With the exception of these two companies, I have never personally experienced a system that does not to at least some degree.firefighter813x said:The Borla does have drone.... pretty much every aftermarket exhaust will have some drone except Corsa. I think the Borla part # is 40085 or the XR-1. I had this on my Fbody and gave it to my buddy to put on his '07 Silverado w/5.3. Sounds better than his Flowmaster 40.
Looking into sport now, anyone else thoughts on the sport? Will this give me the bark I want?helios said:19131347 is the Sport muffler; 19131346 is the Touring. Touring volume is on par with stock, just deeper tone. Go with Sport. Search the part number in YouTube and there's a couple but it's hard to appreciate exhaust comparisons on video, too many variables that distort the real in person sound.
