Sam the GMG bypass should with the GMG side muffler deletes. The entire system looks to be the same as the GT3 system

Total insanity. Just do side delete and keep center muffler. Now you have a Cup system and it's all you could want in terms of sound.

But I want louder, because race car. I have side delete and 200 cell cat headers, sounds great but can be louder, like race car.

Got it. I have the BBi side delete into the third muffler. Had to remove the Sharkwerk bypass and that maybe why. I'll have my guy take another look.

I wouldn't recommend removing the factory side mufflers unless you are relegating your GT3/RS to full track duty. You will lose low end torque with that setup and unless you are hanging the car out above 5500 rpm's, the headers and/or the center muffler delete will give you the most sound/performance needed.

Sam the BBi bypass pipes require the factory muffler. The GMG side muffler deletes do not so you can run their bypass, stock, or the Sharkwerks.

Great! So they're ready to ship right? I'll just wait for the 991RS sound clip after the headers and center section pipes...

I think you would need an ecu tune for that setup
