Has anyone seen a bolt on dual exhaust for the 2.4L. In your opinion what would be the best option to converting the 2.4L to have dual exhaust.
I assume that you mean dual outlet exhaust, as I am not aware of the existence of a true dual exhaust. The most common thing that has been done is to find a RedLine cat-back takeoff and install it. Everything lines up perfectly, the existing hangers work, and it is only necessary to alter or replace the rear valence.
It just requires some welding...not much of anything....take it to a muffler shop. It is quite simple. Almost plug and play if u can weld. All they do is remove your OEM muffler and weld on the new with tips that u prefer.does this require any mods? Or it fits directly in with the shape of the car?
In 2017 I purchased a dual exhaust from gmpartsdirect.com for 1000$. It's bolt on and has hangers for a solid install.
One thing that's surprising is how long it is. To get it from my place to minute muffler we got it there by van - and it didn't fit in the van without leaving the door open.
