NOTE:
I recently installed this exhaust kit on my 1976 Porsche 911, and it has truly transformed the driving experience. From the moment I fired up the engine, the sound was exactly how I’ve always dreamed a 911 should sound—deep, throaty, and aggressive without being overbearing. It strikes the perfect balance between a refined growl and a powerful roar, especially when accelerating through the gears. The craftsmanship is top-notch, and the fitment was perfect, making installation a breeze. If you’re looking to enhance the character of your classic 911, this exhaust kit is a must-have. It not only elevates performance but also delivers a sound that turns heads and brings a grin to your face every time you hit the throttle. Absolutely worth every penny!
My 81 911SC had a horrible drone from 3-4K rpm due to a cat bypass pipe and stock, probably heavily worn muffler. I shopped around and decided the Fabspeed made the right noises for me so I ordered the Maxflo and the 2 into 1 premuffler. Installation took 2 hours. My system came off very easily. Quality and workmanship of the kit are top notch. Everything bolted together well. A little adjustment and looks nice. The startup sound is awesome and it settles into a nice deep, solid sporty sound. The noise inside the cabin is not intrusive at all. The drone is gone. I have been accelerating with the window down to hear the very cool sound. At steady throttle or with the windows up, the system is very civilized. I'm very pleased.
I was looking for a mellow exhaust for my '85 911 that didn't drone, and just gave a slightly deeper sound, and this fit the bill perfectly. Paired with the sport cat it's quiet, with a bit more rumble at idle and bit fatter, throatier sound through the revs. If anything it could be a hair louder or have a bit more bark, but if I wanted that I'd probably just delete the muffler completely. This is a great sounding system that you could drive miles with and not end up with a headache :) Fantastic build quality as well. The welds are perfect.
