Maxflo Performance Exhaust System
Maxflo performance exhaust system for the Porsche 911 Turbo 930 (1976-1989), with radius stress-relieved, hydro-formed muffler cases pulse TIG welded and packed with ceramic fiber and stainless steel wool. Built from 3-inch, 14-16 gauge CNC Bent over an internal mandrel so the tube keeps a constant diameter through the bend, unlike crush-bending. A grade of stainless steel used for exhaust tubing, chosen for heat resistance and corrosion resistance., it bolts to the factory turbocharger, adds around 18hp at the crank (15whp) with reduced turbo lag, and gives a deeper, more aggressive exhaust note with turbocharger whistle. Available in single or dual-outlet configuration with Deluxe Oval or Quad-Style Tips.
Frequently asked
Does the Maxflo Performance Exhaust System fit my 911 Turbo (930)?
This listing is specific to the Porsche 911 Turbo (930). Exact fitment for your year, trim and options is confirmed on your free consult before anything is ordered.
What does the price include?
The delivered price includes the part from Fabspeed USA, freight to Australia, import costs and GST. Enter your postcode to refine delivery; the final figure is confirmed on consult.
How long until it arrives?
Every Fabspeed part is made in-house at Fabspeed USA with about a one-week production lead time, then allow another 3-4 days for delivery to Australia via UPS. That freight is already included in the price.
How much more aggressive does this sound compared to stock?
Fabspeed describes a much deeper, more aggressive exhaust note plus noticeable turbocharger whistling.
Does it help with turbo lag?
Yes, Fabspeed states this system significantly reduces turbo lag on top of adding up to 18 horsepower (15 at the wheel).
Can I switch between single and dual outlet later?
Yes, Fabspeed built in a removable cap-off so you can go from single to dual outlet whenever you like, though the dual setup needs a small modification to the rear bumper valance.
What stops the mufflers from burning out?
The Maxflo mufflers use hydro-formed, radius stress-relieved cases that are pulse TIG welded with 2000-degree ceramic fiber and stainless steel wool packing, which Fabspeed says prevents the burn-out issues seen with other brands.
Who installs it?
Rennen Motorsport in Adelaide, or an authorised dealer near you. Fitting it yourself may also be an option depending on the part, so raise it on your consult; professional installation is quoted separately.
Is it covered by warranty?
Fabspeed products carry the manufacturer's warranty, supported locally through Rennen Plus as the Australian principal. See our returns policy.
Can I just buy this outright, or do I need to talk to someone first?
Every enquiry, whether it's one part or a full build, starts with a free consult. We confirm the exact spec for your car before anything is quoted or ordered.
