    Default Exhaust for the G80 5.0

    Members don't see this ad
    Hello guys.

    I recently purchased my 1st G80. I am interested in upgrading the exhaust to get a little more sound, nothing drastic. Anyone have suggestion or possibly audio clips.

    Thanks Reugoff

    Go read the '15 Genesis section...hard to do an exhaust for the 5.0 without getting the dreaded drone...

    I CANNOT RECOMMEND ENOUGH TO YOU, to look into getting Electronic Cutouts.. you get best of both worlds, you can ride stock quiet anytime you want or you can get a MEAN GROWL, that is better than any exhaust.... BASICALLY, running straight pipes.. the brand i got were the QTP.. all in all for the cutouts and installation at my local muffler and exhaust shop, ran me $925... best MOD, i have EVER DONE.. hands down.. 20170516_122836asdfasdf.jpgdafdseawrdasf.jpgcxvzcxxc.jpg

    The subject of exhaust has been "exhausted" over Genesis forums for years. Borla and Magnaflow have produced cat-back systems. My own personal experience with Magnaflow is horrible drone. Been there, done that.
    Drone is a big problem with any exhaust system. OEMs have addressed the problem with so-called "active exhausts", which are found in Corvette/Comaro and some Jaguars. In active exhausts under light motor load (drone zone) exhausts empty into a large chamber, which lessens drone to a minimum. Under hard wide open throttle a valve opens and exhaust exit through an almost straight through chamber. The valve is either a spring-loaded valve or electrically opened.
    Magnaflow has a Dynomax muffler line, which is an active exhaust muffler with a spring loaded valve. I installed one on a '12 RSpec. Installation is tricky requiring a good exhaust specialist to line up the ports correctly. The result was a nice quiet tone that passed "the wife test", and even nicer when I got on power. Drone was muted to a very low level. Drove the car with the Dynomax for 30K miles with no problems. There is an "urban legend" out there that the Dynomax muffler springs fail, but my experience with it was very positive.
    Dyomax mufflers are fairly cheap like about $125 or less each.
    So, my advice to anyone looking for a nice sound is to go the Dynomax route with just the rear mufflers changed. Don't mess with the central resonator.

    Do you have the name or model number for the Borla or Dynomax exhaust?

    I only found a Borla exhaust for the 1st gen Genesis and it seems the Dynomax VT muffler has been discontinued.

    BTW, magnaflow and dynomax are two separate companies.

    Saintt is correct. Dynomax is a separate company from Magnaflow. I did check the Dynomax site - the VT muffler line is no longer listed, which means it is withdrawn from the market. You can still find VT mufflers on Amazon, Jegs and Summit, but.....?
    This means that drone will continue to be a major problem with any after market exhaust.
