I have Track Edition paired with stock dp. First, it's not all that difficult install to do on your own but you need a buddy. It helps for him to hold parts up while you bolt down the clamps. I did it using ramps you could buy at auto zone to lift up the front end and then jacked up the rear and put it on jack stands. Everything on the OEM came off pretty easily. Only confusion was you have to re-use the little joining pipe that connects the stock dp to this exhaust. The instructions didn't indicate that and I lost my mind trying to figure out why the track exhaust would not reach the stock dp. That joining pipe bridges them together and is required if you're pairing with stock dp.
Sound wise, it is very quiet with stock dp. Almost OEM with a SLIGHT louder idle. Like, you'll hear something but it isn't dramatic at all. Honestly, the whole exhaust is tame with stock dp until you actually get on it. When you do, it does sound very clean. I was personally looking for something quiet due to my age and giving some peace of mind to my neighbors when I turn it on in the morning (or super late for that matter). Yet I needed SOME sound because, I don't want to drive around in a car that sounds like my mother's Elantra... It checks all the boxes.
Lastly, if it isn't sound, it's tips right? Well, they fit the cutouts of my aftermarket ECS Tuning rear diffuser perfectly. Just the right size to feel good because those OEM tips were puny looking. Fitment was easy since you can play with it before settling down. After nearly a year of this exhaust on, the tips are still ALMOST in their same position. Of course some movement would of occurred as things settled in and the right side tip seems to have raised a few millimeters than where it started. Regarding silver/black tips, without a doubt silver. The black are going to disappear in the diffuser and won't be as noticeable. I wanted to be able to see what I bought when I'm walking towards the car, so I made sure they would be silver so that they stand out.
Pic from the same day I installed the exhaust. Was a very happy day for the car for sure.
Lastly, I'll leave you with a pro tip. There is a little black bar in the center area of the car where the exhaust sits. After my install, after about a month or 2, I got a crazy new rattle introduced. Turns out, the exhaust was hitting that black bar. I took the black bar off (very easy, like 4 screws total) and wrapped it in a heat sleeve that had very nice cushion that was around 15 bucks at AutoZone. Rattle went away after that. Just keep that in mind in case you hear anything a little after install.
