2009 Genesis V8 Magnaflow Cat-Back (16497) HD VIDEO

I will probably be quieting down my exhaust by installing a Magnaflow Tru X-pipe muffler in place of the current X-pipe. I'm going to drive it as is for maybe a couple of months to see how the carbon build-up in the mufflers changes the sound but I don't think there's any getting rid of the drone sound without making the change above.

Did you ever install the Magnflow Tru? Curious to know if the drone disappeared.

I looked at Borla and think the reason for Borla's more raspy sound is the absence of the "X" pipe the MagnaFlow has.

As best I can research, the "x" pipe gains a little more power than a "H" connection.

I'm a retired Geezer and use the Genesis on LONG trips, and think that any drone would become annoying after a while. I have a MagnaFlow and intend to do a "partial install". I will keep the OEM system intact from central resonator forward, using just the MagnaFlow mufflers. I will weld a flange to the MagnaFlow pipes so I can easily restore to stock OEM.

My next stage would be to cut out the "X" pipe in the MagnaFlow and fit it in place of the rear cats, which appear to be redundant. I suspect there are connections between left and right pipes within the big OEM central resonator, which attenuate noise.

Alternatively, I can fit a couple of small straight-through "race mufflers/resonators" aft of the central resonator on a straight section of the MagnaFlow piping.

My ultimate objective is a freer-flowing exhaust with a bit more V8 sound.

I may have to drive to Salem to check this system out...
