2023 G63 Aftermarket Exhaust
Hey Everybody!
I know this topic has been discussed a few times on this thread but just wanted a little bit more insight. I am looking into buying the Akrapovic exhaust for the my g63. I have never heard one in person but everybody seems to love it. On some videos, it does not seem to be much different than stock. I know this might just be the mic but wanted to get more insight on somebody who has one or heard one. Is it much louder and is it worth the price? Thank you in advance for the help!

Just drove a g63 that had it. It’s really good.
But I thought it would be even louder
I’m Wondering what is louder/better

Had the Fabspeed installed for a couple days and it sounded like garbage. $4,200.....you get what you pay for, but all in it was close to $6K with tax and installation. Their support is junk as well, they could have cared less it was designed horribly.

Thanks for sharing. I was considering that one too and now crossed it off the list.
This one is even cheaper, I'm potentially considering it (Vivid Racing): https://www.vividracing.com/-p-154025217.html

What is yours guys opinion on the Fi exhaust? seems like it is a few grand cheaper and based on videos, maybe even a little louder? I know the build quality is not as good as Akrapovic but in terms of sound/tone/pops

No need for ECU tune or check engine light, you just need the high-flow cats.
https://redstarexhaustusa.com/conten...ee-guide-.html
You can go with HJS 130mm or Gesi GEN2 5”.
I always go with the HJS. I didn't put them on my G550 yet, but I had them on my GL63 with zero check engine light.

Fi Exhaust sounds great. I've done it on a few G's and it will get you a little more rumble than stock. Not sure why someone said their build quality isn't good, because that has not been my experience. I've done them on G Wagons and RSQ8/Urus and they are all very well made. ALL of the exhausts from just about every manufacturer will give about the same amount of sound assuming it is a muffler with flaps type set up. The only way to get it much louder is to do downpipes, and most will require a tune to run without a CEL coming on. Looks like someone posted Redstar high flow cats will not cause CEL, so maybe try those. I have no experience with them. For the price difference betwen Akropovic and Fi I'd say the Fi is the easy winner given they will both give about the same amount of volume.

How much louder than stock would you say? Seems like in videos its still pretty mild but hard to tell. Just trying to justify spending that premium unless the sound is not there

I don’t really remember what the original sounds like now that I’ve had the new one on for a few months but I do remember feeling blown away after it was installed. with flaps closed it sounds almost stock but in sports + , it’s like you’re riding an angry dragon. Videos don’t capture it accurately.
