Kia Stinger 3.3T - Magnaflow Performance Catback Exhaust System

Magnaflow Catback Exhaust

I’m very happy with this purchase. I wasn’t too sure when I first got it, because the exhaust on YouTube videos don’t always sound the same in person and varies on what they have already done to the car. I however am happy, because it had the same throaty/guttural sound that I heard in the YouTube video I saw. I also paired this with a catless downpipe, which attaches on the opposite side of the cats on the exhaust-side of the turbos. So it more of a midpipe and currently doesn’t throw a code.

Magnaflow for 3.3 stinger gt

Ok so before I purchased this cat back I never hear any other ones in person this one eighter and I know YouTube videos never really can tell if you will like it or not so why I choosen magnaflow finally? In my opinion this one is a Best looking cat back for a stinger but I know for most of us first is a sound and the sound of this exhaust is like 85% of what I wanted so I am able to tell you guys ita a good one even people saying it's not loud yes it's not loud and could be louder but in my opinion who want this car to very scream? I don't and this exhaust is the one that makes me happy in every speed and rpms no drone at all even on the highway you have nice sound in the cabin and nice aggressive sound outside (I gave it to my friend and he fly by while I was outside an I just said that's f*ckin nice) if you step on it for sure people will turn heads to check what is Going on and remember never listen to people about any exhaust if they just watched YouTube video only

Just what I was looking for.

Coupled this with secondary cat-deletes. The Magnaflow is a well-engineered design. I saw a before and after dyno of just adding the Magnaflow which increased power from 331whp to 381whp! Add that to the 30whp increase from the secondary cat-deletes, and that should be over 400whp... Theoretically. Added KN panel filters to ease breathing a bit more as well. All of that changed what some sensors were seeing and car ran a little erratically for a few days. Took a full tank of gas for relearning. Car feels great now. I have had LOUD exhausts on past cars, (Nameless, Skunk2, etc), and that was not what I wanted here. This exhaust is audible, with a nice tone at idle, light load and cruising but can still be drowned out by turning the stereo up half way. You can still hold conversations fine. It will turn heads under hard acceleration though. Perfect. Just what I was looking for. K8 Stinger Store is great! Much better than it's competitors.
