Downpipes for the 3.3T Genesis G70 | DC Sports
If your Stinger or G70 sounds muted for a twin-turbo V6, the gasoline particulate filters are why. Hyundai and Kia built GPFs right into the factory midpipe, and they're one of the biggest restrictions and sound-killers in the whole system. This DC Sports midpipe removes them and replaces the section with 2.5-inch mandrel-bent T-304 stainless. The 3.3 finally gets to breathe out and sound like the engine it is, and it bolts straight to your factory hardware.
GPF Delete, Not A Cat Delete
Worth being clear about, because it's an important distinction and it's good news. This pipe removes the gasoline particulate filters built into the factory midpipe. Your catalytic converters sit upstream of this section, so they stay right where they are and keep doing their job.
That matters for a couple of reasons. GPFs are the main thing choking flow and muffling sound on these cars, so pulling them is where the real gain is. And because you're keeping the cats, you're not gutting the emissions system the way a true cat-delete pipe does, which makes this a much more livable modification on a car you actually drive every day.
What You Get Out Of It
Two things, and the sound is the one you'll notice first. GPFs are essentially filters sitting in your exhaust path, and removing them takes a significant muffling element out of the system. The 3.3 twin-turbo goes from politely quiet to genuinely present, with a deeper note that shows up hard under throttle. On the flow side, replacing that restriction with 2.5-inch mandrel-bent piping lets exhaust move out more freely, which sharpens throttle response and helps the turbos do their work. Mandrel bending matters here too, since crush-bent pipe pinches down at every curve and gives back the flow you were trying to gain.
Built To Last And Bolt Right In
It's T-304 stainless, TIG welded, mated to CNC-machined flanges. Stainless that won't rust out after a few winters, welds that survive real heat cycling, and flanges precise enough to seal properly instead of leaving you chasing leaks. Because it's built to factory dimensions, it bolts directly to your OEM equipment with no cutting and no fabrication.
Fitment
This midpipe fits the 2018+ Kia Stinger and the 2019+ Genesis G70, both with the 3.3L twin-turbo V6, rear-wheel drive only. (Can also fit AWD models. See note below)
Who Should Run This Midpipe
This is for the Stinger or G70 owner who's tired of a great engine sounding like a rental car. Removing the GPFs is the single most effective change you can make to how these cars sound, and you're keeping your catalytic converters in place while you do it. Confirm you're RWD, bolt it up, and go hear what your 3.3 has been holding back.
NOTE: Made specifically for the RWD platform but still can fit the AWD models. On the AWD models you will just not be able to utilize the tab for the bolts in the middle of the downpipe. Once bolted up on both ends the downpipe is already secure and the use of those tabs is not necessary.
