Thanks! 👍 I'm in CA, so definitely trying to avoid a CEL. And with the stock system + single midpipe and burbles off it's not louder than the stock system, only changes the sound?

There is no system check on the midpipe so nothing to throw a CEL for.

As for sound it will probably increase slightly but I've not measured before and after, it's mostly the change of tone.

Perfect! That's exactly what I'm looking for.

id imagine itll be a lot louder than the stock midpipe as it removes both resonators & 2ndary cats

It doesn't feel significantly louder with my MPE than it did stock but then again the MPE was loud to begin with. Feels slightly louder but not overkill like a downpipe would.

Biggest change I've noticed is cleaner overrun and a deeper less raspy sound.

I do think going into one pipe might help mask the volume increase and that the overrun being cleaner and more pronounced also plays an effect to trick you, as without burbles or overrun it's maybe 10-15% louder I'd say simply because it's much clearer, but then again I never spend time behind the exhaust.

Main objective is that it's not obnoxiously loud and doesn't draw unwanted attention aaaand it doesn't require any coding while making the exhaust just the right volume and sound

oh i thought he was talking about the stock midpipe & not the MPE. in that case MPE + AA probably wont be that much different in terms of volume since the MPE is already loud

My car is a 2018 F83 ZCP, so it comes factory with the MPE exhaust from what I understand? I've only had my car for about 1 month, so I'm still learning some of the basics. When I was asking about sound level I was referring to whatever my car would be considered with the only aftermarket part being the single midpipe...besides stage 1 BM3.

No only car that comes stock with MPE is GTS and it has it's own version of it.

MPE is always an add-on.

Ah, okay. Thank you for clarifying. But the ZCP exhaust is different than the base?

Yes ZCP is different than base and sounds better than base imo, louder more overrun.

I think the ZCP actually is a bit livable or mellow tone than MPE and i have MPE.

MPE is very aggressive and Raspy and the opposite of sounding good. People always misinterpret good for aggressive but they aren't the same.

A disturbed lion sounds aggressive, he doesn't sound good though, as long as you are comfortable with the distinction you can make your choice

The raspy sound is what I'm trying to get rid of, so I'm leaning towards the VRSF single midpipe with the rest of the exhaust stock. I've just don't want a car that's going to be loud when it's not supposed to be.

The valves help with that. The resonated equal-length mid isn't raspy at all. The non-resonated version rasps quite a bit at higher RPM. I have both versions, and I go back and forth on which one I like better.
They both sound better than the single, which is basically a louder, deeper version on the stock sound. The single does not rasp at all whatsoever, though, so if that's your main concern you can solve that with the single.

The single midpipe is more in my price range of what I'm willing to spend to improve the sound. The equal length sounds great, but I'm just not willing to invest that much into changing the sound. If they were the same price, I'd pick the equal length.

That's what I said. And I bought the single first. But then I started searching for mufflers to go with it, and had a hard time finding [videos of] one that wouldn't just amplify the standard S55 fart sound.

The equal length exhausts are the only ones that make these cars sound like a normal straight six, in my opinion, which is what I wanted. It's more money than I wanted to spend, but it's cheaper than a $4,XXX full exhaust that produces a louder version of the same farting-across-a-rubber-band S55 sound.

Maybe I'm better off leaving things alone then. I have no desire to change any other part of the exhaust. I don't want to make the exhaust louder, only remove the raspiness and make it sound more like a true inline 6.

I always call it a Buick or a Pontiac but a Lumina will do!

Same engines
I would also have accepted Beretta.

The resonated equal length midpipe will accomplish both. It's the only thing that's going to make it sound like a true I6.
The only other exhaust I have heard that gets close to normal I6 sound is the Magnaflow, but I hear that it drones quite a bit. It's also pretty loud and costs $3K. If you don't want loud and don't want to spend $3K, and want true inline 6, resonated equal length all day.

The single midpipe will remove 100% of the rasp, but the sound will still have the same weird character.
