Frequently asked
Does the Maxflo Performance Exhaust System fit my 911 G Series (3.2L)?
This listing is specific to the Porsche 911 G Series (3.2L). 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.
Will this exhaust be too loud for daily driving?
No. Fabspeed describes the Maxflo as deep and throaty but street-appropriate, tuned to sound exciting without waking the neighbours or irritating your passenger.
How much power does the Maxflo add?
Fabspeed's own testing showed gains of 4 whp and 5.4 Nm of torque, along with improved throttle response.
Does fitting it require any cutting or welding?
No, it's a simple DIY bolt-on job, though Fabspeed notes the factory rear bumper needs slight modification for the second tip outlet to sit properly. Rennen Motorsport or an authorised dealer can fit it too, for owners who'd rather leave it to a workshop.
What is the exhaust built from?
It's built entirely from T304L stainless steel, with 14-16 gauge CNC mandrel-bent 5.7 cm tubing and mufflers that are hydro-formed, pulse TIG welded, and packed with ceramic fiber and stainless steel wool.
Which option should I choose?
Dual outlet requires a slight modification to the factory rear bumper to fit the second tip outlet. Single outlet needs no bumper work.
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.
