You will not regret doing this is all I can say.
I assume the BillyBoat bypass is a lot louder? Sounds like a winning mod!

I would say the two are complementary. Gundo will give the car a deep and aggressive tone whereas the x-pipe will add an almost exotic wail throughout the mid-range. Together, you'll also get the burbles and crackling on the overrun which also sounds fantastic.

I maxed out the holes on the muffler pipes and am glad I did. It is aggressive and what I was looking for. I think the Billy Boat X pipe is also a must on the 997.2 and to get the mufflers out you have to undo the 2 cat bolts that are the hardest to get at. There is no drone and sitting in the car it is not annoying by any means. Behind it I'm sure it is not as loud as all those Harley's out there but one definitely knows there is some whoop ***
