3.3TT '22 Exhaust Questions?

[K8 Stinger Store]

Pretty cool man. That’s the only reason I didn’t get mbrp’s 2022. Since people said the valve didn’t make much of a difference.

Thanks for sharing. Looking forward to your videos.

I’m confused by your response, I don’t think he indicated in his message that the valves didn’t make much of a difference.

Unless I misunderstood, I thought he was saying there was a pretty big difference when the valve was open and closed.

We have sold over 30 of the MBRP Active Exhaust Systems for the 2022-2023 Stinger, and we haven’t heard anyone state that the valves don’t make much of a difference. With the valves, completely closed in Eco mode, versus the valves completely opened in sport mode, it should make up a significant difference, and should be very noticeable. This would apply for any active exhaust system for the stinger since there’s a pretty decent difference between the valves being opened or closed.

Yeah I understood the same about borla open/closed

Good to know.
There’s a few videos online from owners saying the noise volume is about the same from opened/closed.

And the more noticiable difference is the tone from open/closed.

I have the MBRP active exhaust system and can there is a difference between open/closed.

’"With the valves, completely closed in Eco mode, versus the valves completely opened in sport mode, it should make up a significant difference"

I thought a less restrictive exhaust system would improve gas mileage, but apparently Eco mode closes the valves. What am I missing?

 

[Erocked]

The MBRP has very little change dB wise with valve open or closed, tone wise, it is quite different!

 

[OHstinger]

Yep thanks. My only issue with KSR is that they have too many options! Its hard to judge what my car would sound like when they offer so many configurations.



Sounds good thus far! Especially want to hear your opinion on the cabin noise. Some people report that previous Borla exhaust droned too much in cabin if you didn't add new tips.

Yea noise clips are minimal as it is brand new. If you have instagram, check out my page, ohstinger. I have some clips there. I have the muffler/resonator option. It is certainly loud, they will offer valved very soon, but it is not too loud at causing speeds.

Is that an actual crossover pipe, or is the exhaust a true dual exhaust?

I believe dual exhaust but hard to tell. There could be an opening in that weld.

It was that hard to tell part that led me to ask. I couldn't tell if that X pipe was just 2 pipes welded together for handling and packaging purposes, or if it was a true X pipe

I agree with this. It’s very different to the point I don’t want to drive in comfort/eco unless I’m just cruising quiet roads. MBRP for the win. Borla sounds really nice too. Glad we have awesome options. Cheers all

Finally drove the car for a good 2 hours. I will post a video next week to try an capture the sound difference of the valve. However, the sound difference is pretty big with it opened and closed when cruising. In sport mode there is a decent amount of drone but nothing too bad if you ask me, in comfort mode the drone is about 90% gone, if you play music you most likely won't hear it. When taking off in comfort mode it can still be decently loud depending on how much throttle you give it. All in all, it won't be quiet like stock. I would say just cruising it's a tad louder than the stock exhaust in sport mode.

Great info. Glad to hear comfort mode eliminates most of the drone. I'm ok with some drone in sport, as I don't always drive around in sport. Plus I could probably do some exhaust wraps or 2.5inch extensions to have the pipes extend more into the stock tips. That reportedly helps with drone on previous aftermarket exhausts. Eager to see your video!

The only other deciding factor for me will be price. The MBRP system is pretty expensive already, and I'm sure Borla will be more. I really don't want to pay much over 2K for an exhaust system. Hopefully the pricing will be competitive with MBRP, but we'll see. I have a few more months to save $$$ to make up the difference, but paying that much is still doesn't sit well with me lol.

For the most part lets say you are on a flat surface maintaining speed or gradually increasing speed slowly, you can barely hear in comfort mode and any music you play drowns it out. But if you speed up in any way you will hear it open up even with music playing just not on the level of sport mode but it may be louder than some would want. I am fine with it personally. After driving it some more I can confirm the burbles are absolutely insane! They are not that loud on the inside but with no music playing it burbles nearly the entire way on decel pretty clearly. I also heard adding sound deadening in the hatch area can help too but for my taste I don't see any reason to modify anything yet. Today is my day off, later I will be heading to one of the Canyons in my area to record some footage. Gonna grab POV shots and kind of review the sound in certain situations, and I will also grab exterior shots of the car doing fly-bys and also mount a gopro behind the car if I can find my suction mount.

I agree, most I ever spent to have any exhaust replacements was always less than $500, even had a custom exhaust with a magnaflow muffler and vibrance resonator done to my 280z and only cost me $450, so anything above $1000 seems crazy expensive to me which is why I didn't sleep when I saw the opportunity to get a free exhaust with Borla. I want to guess the price of the Borla exhaust will probably be around $1800-$2200. I remember the guy did say the setup is somewhat similar to the last system aside from having to adjust some of the pipes and I believe using a different muffler design for the valve more than likely.

Honestly just looks like they added a valve on one of the tip outlets just to utilize the muffler more, other than that the exhaust looks identical to pre-2022 model.

They told me it's similar to their previous version aside from a small pipe difference and i believe internally inside the muffler. Have not heard how the old one sounds in person but based on videos the active version sounds less raspy.

Sorry, that was my auto correct. I meant "Sport valving". There is an electronically actuated valve that opens on cold start, as well as when in Sport mode that drastically changes the character of the exhaust note.

When its cold shouldnt you see exhaust coming out all 4 tips when in Sport mode? Only comes out through the active valve tips. 22 Stinger Elite 3.3 tt AWD

The valves only open when the exhaust gets warm. When you turn off the engine they stay open until the exhaust cools down. 23 Gt Elite 3.3tt. From my experience this is in all modes but I really only drive in sport mode.

Hey everyone, new here and been looking at 22' GT2's and plan on purchasing very soon. One question I have regarding the exhaust is whether there are aftermarket exhausts/mufflers that would be better than stock from a flow restriction/performance standpoint, but NOT lead to an increase in how loud the exhaust is? I know that is counter to what most are looking for upgrading their exhaust, but I am a big audiophile and plan to do a really nice custom audio system in this car and would prefer to not hear the exhaust while cruising in Comfort or Eco modes. I have no issue if things get loud in Sport mode. Several of the cars I'm currently looking at have aftermarket exhausts on them and I'd hate to pull them out to go back to stock if it can be avoided...

Should I just stick to the stock exhaust, or are there things I can do with a performance exhaust to help with noise. I will already be doing a bunch of sound deadening to the interior so that's already covered, only interested in hearing about the exhaust. Thanks.

I probably would stick to the stock exhaust entirely including secondary cats and use the valve system the car comes with. The two areas of restrictions of the stock exhaust are the mufflers and secondary cats. I have a borla non valved on my 23 GT2 with ark downpipe and its pretty loud but I am switching to the 22+ borla active valve version by end of his month to be able to control the sound a bit and hopefully have less drone as the 18-21 borla version is bit more raspy and more drone inducing on highway. Initially when I got the ark installed it was really loud but it has broken in and become more refined and toned down just slightly.

If you want to keep it more tame but be able to have more exhaust note in sports mode then the mbrp pro active valve might also be a good option as well as it's louder than stock in sports mode but not by a large amount like borla is. The good thing is since you are doing sound deadening it will help with the drone. Generally most of us tend to notice drone way more going uphill on highway with any aftermarket exhaust. Exhaust tips are also pretty much a must with any aftermarket exhaust to make sure the sound exits outside of the bumper so it doesn't bounce back into the hatch thus causing terrible drone. One thing you could also do is keep stock catback including mufflers but do secondary downpipes. Will increase sound but not by much really.

Thanks for the reply. This was very helpful. Hopefully I'll be officially joining this club soon!
