...No worries, it's all about the fun.
Again, for the record, install whichever exhaust makes you happy, that's what having fun with your car is all about.
I just wanted to post documented information as to the reason why two muffler setups drone. I just wanted to educate the collective on WHY the Beluga, Borla, et al sound the way they do. It fundamentally goes back to how Porsche engineered the drivetrain.
I'm NOT saying that the Porsche way is the ONLY way, or hit the highway.
I'm just saying that Porsche built them this way for a reason and because they did build them this way, if you fundamentally change the muffler from a one big can to a two small can setup, it will most likely drone because of how the muffler was originally designed to be an integrated part of the drivetrain and act as a mass balancer to the entire vehicle.
If you decide that that is not important, well, that's perfectly fine and I have zero issue with your choice, again, I just wanted folks who troll this forum to understand why these things sound the way they do.
The car companies invest millions in testing their systems. Any time you change out a major part for an aftermarket alternative, you run the risk of unintended consequences. In this case, you will likely introduce a headache inducing drone while cruising down the highway.
Since we are 20 years past the original vehicle launch, a whole new generation of folks are buying these cars cheap on the used market and want to have a fun car and that means a more fun exhaust note for many. I get that. I wanted that, too.
Being the old man that I am, I use my Box as a vacation car and I needed to find that compromise between a more fun sounding exhaust and one that didn't give me a headache halfway to the Grand Canyon.
After researching, I found out about the muffler design and that is what led me to purchase and install the FVD Brombacher "Sound Version" muffler and secondary cat bypass pipes.
I'm in Porsche exhaust heaven!
I found the Holy Grail exhaust for ME.
She sounds like I'm racing at LeMans with Steve McQueen from inside the car when I'm on the throttle, is silent when I'm on the interstate at 75mph in cruise control in top gear, and is JUST loud enough outside the car that I get nods of approval from car guys, but does not attract cops or piss off old ladies or wakes up the neighbors when I leave the house at 5am.
YMMV.
Keep having fun with these great old cars.
I'm glad you are here.
Enjoy!
