Go with the DynoMax VTs, the best muffler for our V6 by far with pretty much no drone at all. If u wanna keep ya Borla mufflers then ya best bet would Be to install the stock resonators back in. Personally, I would put the stock resonators back on regardless. Gotta keep at least the stock resonator or stock muffler to have a pretty good sounding exhaust on these cars. Just my opinion though....
