Sounds pretty good stock still.

Sounds 100000000x times better than all the Magnaflow exhausts everyone seems to be putting on

Installed the Stillen catback exhaust system on my 2013 Hyundai Genesis Coupe 3.8 Grand Touring on 28 Jan 13. It looked great. However, the loud, irritating and constant droning inside the cabin was more than I or my wife could handle. Uninstalled it 30 Jan and put back the original exhaust. Called Stillen, and per their return policy, they refused to take it back under any circumstances. Learning to appreciate the outside sound and inside quiet of the original exhaust.

Is magnaflow quieter?

Speaking from someone who has a Stillen on my 2010 3.8 GC, it sounds great, but the comment is misleading. It has a definite drone around 2k RPM.

Still an amazing exhaust if anyone wants something different from the usual ARK/magnaflow options.

That extra 9 horsepower made the wheels spin!

[nitro300]

is this system only for the 3.8

I know!!! I test drove one today as well lol, and I ended up trading in my 2.0T for it. Best decision ever.
