Thank you so much for your help haha I feel kinda noobish  |
Stillen's exhaust is not a dual exhaust. The reason being is that the y-pipe forces the exhaust to flow into one pipe for a brief moment in time. A siamese x-pipe or h-pipe allows the exhaust to flow in their own pipe for the full length of the exhaust. The x and h connections typically result in better exhaust scavenging which equals more power.
Now, a
true dual exhaust is an exhaust with two completely independent pipes without any sort of cross connection.
I honestly couldn't tell you if a Nissan dealership would void your warranty if they installed an exhaust. They need to prove that the aftermarket part caused an issue to void your warranty (Moss Warranty Act) which is highly unlikely of any cat-back exhaust.
