Those Borla set ups sound mean! In person the nastiest imo is still the Flowmasters. Twin 2.5 or 3" 2 chambers behind an LS sound like a PRO mod car if its cammed lol. But DRONE!!! yikes....

I like the Aerochamber. Flow well, sound good, little to no drone, lots of size options. A tad heavy though but might makes right

 

dynomax and cherry bomb make a 3 1/2. for a good price,

 

I run a Magnaflow too, it sounds very nice without being extremely loud like my Camaro. So I installed a QTP electric cutout before the muffler, I can be loud when I want and quiet when the fuzz is around lol. But if you want loud, I run Dynomax bullet's with an off road x pipe on my Camaro, crazy loud but awesome!
