Thanks to everyone on the forums and GMG for all the positive and helpful advice! After an 1hr and half she's installed!




(sorry for the crappy youTube video)

Glad you actually did it : )

That is a great looking and sounding center bypass.

Any plans of disconnecting the valves? I have been thinking of trying this to see what the sound difference would be.

Nice work !

I actually like the idea of having the valves.. I unfortunately live in a neighborhood where anything loud becomes a Facebook post noise complaint lol

Agree with you, Charles.

It's awesome to go from (semi) stealth to crazy loud with a push of the exhaust button.

The GMG center is spectacular. All of these after market center bypass systems sound great but I think the GMG is the most sinister. Love it.

Sounds great. Next up -- side deletes!
[I hope that you didn't stop the parts removal at just the bumper (as pictured) but also pulled the support frame and heat shield; otherwise, I'm not sure you gained much room vs leaving the bumper in place.]

Charles7970

Yup! i had everything removed or that would've sucked lol

Drone. Lots and lots of drone.

Drone at 4k+? That's odd cause I don't have it. I thought the GT3's only idle at 4k and above, lol.

In all seriousness though to me it's not that bad and is actually much quieter than my GTR, but there is drone.

Drone with the side muffler deletes?

I have an Akrapovič center bypass. I don't think it's much louder than stock.

I have FVD? single tube side muffler deletes coming into a GRP center bypass with the top/small tube blocked off. Valves unhooked and plugged. I have noticeable drone between 2K and 2.3K. I would say to just stay out of the drone-range but that never seems to work so I've just gotten used to it. Passengers don't say anything about it unless I bring it up and then they all say they can hear it too. A couple of 9K runs and they forget about it. It's crazy loud; if you have complaining neighbors be prepared to hear from them even if you attempt to 'quietly' sneak in and out of the neighborhood.

Very nice! I also have the GMG center. Having the itch to switch up entire exhaust. But I think best to wait till next year. Just got car back from getting a tune. Tuner made it so the sport exhaust button opens and closes the valves. BRILLIANT! car sounds bananas now. I love it!
