Here's a clip of my friend Lance's 2014 Optima with the Injen exhaust system. stock motor, down and mid pipe.


Here is a quick clip as he revs it as he passes me on the side of the road

And lastly, one last clip of him taking off from a stop from inside my car. A few seconds in you can hear my Magnaflow custom exhaust from within my car.

Awesome clips JasonS, which exhaust did you end up with in the end?

New clips for the thread!

Here is my recently installed exhaust

Stock downpipe
3" midpipe to rear axle, spits to 2x 2.5" mufflers
Cat delete

Running the 93 octane BTR tune

Overall happy with the sound at WOT, but can drone a bit while city driving. It's pretty loud though, so I'm looking into adding a resonator or something to quiet it down. Possibly some dyna-mat on the floor of the trunk or rear seats.

Still, it sounds badass.

Sorry about potato camera videos...

Just installed a Magnaflow 19237 that I got off Amazon for less than $700.

The thread I made is here;
http://www.optimaforums.com/forum/6-optima-engine-technical-discussion/140305-magnaflow-19237-cat-back-exhaust.html



But for ease of access here are the vids I have of it;


Driving away from the camera at 3/4ish throttle


A quick hard throttled 0-60 with all windows closed


A quick hard throttled 0-60 with all windows open



Light acceleration as I drive by. I was probably doing 25 and accelerated to 40 at a moderate rate as I drove by.



And here is a startup of the car cold for the first 20 seconds or so of high idle until it drops like normal, with a few revs at the end. This video was taken in an open, double car garage.

Magnaflow 19237 catback installed yesterday and it sounds perfect. barely noticeable with the windows up, but sounds **** good from the outside or with the windows down. Not much drone thanks to the fact my Optima is a manual and i can control revs better.

Yeah! That is NICE. Even more so if you can wait for Amazon to drop the price down to sub $700. It's a real steal!
My videos really don't do justice to it because I think my camera makes it sound like it drones way more than it really does.
