The Fabspeed Maxflo Exhaust is the perfect exhaust for everyday street driving and anyone that is looking for a system that isn't too aggressive but intoxicating throughout the RPM range. Improved sports car sound; deep and throaty while maintaining a street-appropriate volume. No need to worry about waking up the neighbors or irritating the passenger, the Maxflo exhaust is the ideal mix of an exciting and refined sound.
NOTE: Requires slight modification to the factory rear bumper for proper fitment of the second tip outlet
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.
