Maxflo Cat Back Exhaust
A direct-replacement, mandrel-bent 2.5-inch cat-back exhaust for the Acura NSX Type S / TT (2017+), replacing what Fabspeed describes as the factory valved exhaust's heavy, bulky, overly complex design. Precision manufactured in the USA using HAAS CNC, flow waterjet, and Unison mandrel-bending equipment, it saves 19 lbs (8.5 kg) over the stock valved exhaust and brings out more sports car sound and turbo spool. Fabspeed states it produces no catalyst-related check engine light and stays compliant with emissions and warranty rules. Comes with deluxe quad tips in your choice of finish, which fill out the rear valence surround. Because the system removes the factory electronic exhaust valves, Fabspeed offers optional plug-and-play valve simulators to prevent related system faults.
Frequently asked
Does the Maxflo Cat Back Exhaust fit my NSX?
This listing is specific to the Acura NSX. 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.
Do I need the exhaust valve simulators?
If your car has the factory valved exhaust (fitted to essentially all 2017+ models), yes; 2017-2018 cars with the factory non-valved exhaust don't need them.
Will this trigger a check engine light?
No, Fabspeed states it produces no catalyst-related check engine light and stays compliant with emissions and warranty rules.
How much weight does it save?
19 lbs (8.5 kg) versus the stock valved exhaust.
Which option should I choose?
The valve simulators are worth adding if your car came with the factory valved exhaust (essentially all 2017+ models) - they plug straight into the factory electrical harness connector and prevent fault codes caused by removing the valves. Skip them only if your car already has the factory non-valved exhaust from 2017-2018. The tip finish (polished stainless or satin black) is purely a look, so pick whichever suits the rest of the car.
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.
