3.3TT Kia Stinger Aftermarket Exhaust Information and Discussion

[rpoffen]

Question. I have a 2022 Stinger GT2. From what I understand it has a variable exhaust from the factory. I believe a aftermarket cat back exhaust would eliminate that. I have ordered a Megan Race Cat Back exhaust. Is this a wise decision to do this or should I just stick with the stock exhaust?

Yes, from what I heard, the variable exhaust feature would go away, and you may need some kind of code eliminators to prevent a CEL.

I have Ark Secondaries + MBRP Catback with stock tune. I think since I added AEM intakes, I overboost during hard accelerations when the weather is cold out.

Forgive my ignorance but, is this a good or bad thing?

Bad. But having a JB4 with the EWG cable option solves that issue.

I was considering the ark dp with stock exhaust, I have the injen cai in route. It definitely gets cold in Wyoming so… is this going to be a bad move? As great as the jb4 sounds I can only get 91 octane.

Bad, because when that happens, the car goes into limp mode and doesn’t build boost until you turn the car off and on to fix it.

Could be a good thing to protect the engine from an unexpected condition.
Seem's the '22's are more prone to this, even in stock form. Maybe they tweaked the tuning a little bit, and now have unintended consequences.

I have the same setup though with a JB4 on MAP 0 to I install my plugs. Map 0 is stock and haven't had an issue with overboost in the cold. Was you car warmed up at the time it happened?

They have maps for that.

Yeah, I was on the highway at the time after driving for 30+ mins. Usually happens around -10c or lower I found it.

Picked up a “new” exhaust setup from a previous Stinger member few days ago. Going to get it installed this month when I find time. Kunstwerk Racing EVC Catback + lower Resonated downpipes!

Do they still make that exhaust ? When I was surfing the web couldn’t find it anywhere

They make a newer version called “HPX Limited”, but to me it doesn’t sound as good as the old one.

Has anyone posted the JunB ‘22 specific exhaust with EVC? Just ran into it on Tuscani. Looks like it lines up and maintains all functionality.

I read a post here a few months ago about the possibility of MBRP offering an exhaust for ‘22 Stingers. Has anyone heard from them recently as to when that light happen the previous post mentioned March but we‘ll be into May soon enough. I tried to contact MBRP twice via email over the last few weeks and haven’t received a response.

Just came across this post in the Engine, Drivetrain, and Exhaust Discussion forum.

Thank you. This summer is a big window. Hopefully it’s not like a government contract that has a sliding completion date. Fortunately I’m not in a big hurry so I’ll wait a bit longer.

I overboost with just injen and mbrp on stock tune. It's wild to see how unique these cars are lol

Got my Kunstwerk Racing EVC Catback + Resonated secondary downpipes installed yesterday. Currently running no exhaust tips because my old CF oval tips don’t fit, I need 51x105mm. With the valves off, it sounds a bit louder than stock outside and inside (no tips at all) and it’s so loud open that my interior vibrates lmao.

Also had ATQ Subframe Collars installed by the owner of ATQ himself at his shop. Car’s suspension feels like it’s in sport mode when in comfort but now it handles some bumps more better now and overall feels to flex a bit less when pulling into my driveway.

Ps, I’m suprised how little rust I have underneath even with over 106,000km in Canada. Lol

I just installed Jun BL downpipes/midpipes. One of the best mods I ever did. Exactly the sound I wanted and I have stock tune and MBRP SS

I've been strongly considering the Jun B.L midpipes based on lots of comments around here (and elsewhere), some videos, etc. I'm curious if you could shed some light on a few things:

1. Do the Jun B.L midpipes come with gaskets, or will standard / stock gaskets for the stock midpipe section fit fine?
2. Is there a recommended importer / vendor for Jun B.L in the States? One who ideally has competitive pricing and provides domestic support for warranty and/or shipment claims?
3. Any tips/tricks, or is it as straightforward as it seems? (And if you recall, which sockets did you use? Short/mid/deep? etc.?)

I purchased mine from K8 store during their Black Friday sales and had my mechanic install it. It comes with everything you need, straight forward install
