Fabspeed's RSR Header Muffler Kit is a complete headers-back exhaust for the Porsche 911 Carrera (1976-1989), giving loud, aggressive Cup-car sound through dual outlets. The RSR long-tube headers use equal-length primary pipes with F1-style pyramidal investment-cast merge collectors feeding into Fabspeed's Maxflo muffler, and dyno testing showed peak gains of 17whp and 13 ft-lbs of torque at 3900rpm. Built from 14-16 gauge CNC mandrel-bent T304 stainless steel, it saves up to 23 lbs from the rear of the car depending on the exhaust and tip options chosen. It's a DIY bolt-on install, though fitting the second outlet needs a slight modification to the factory rear bumper, and exhaust bolts should be retorqued to spec after the first heat cycle. Rennen Motorsport or an authorised dealer near you can fit it instead, for owners who'd rather not.

Frequently asked

Does the RSR Header Muffler Kit fit my 911 F Series (3.0L)?

This listing is specific to the Porsche 911 F Series (3.0L). 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.

Does fitting the dual outlets require any bodywork?

Yes, a slight modification to the factory rear bumper is needed for proper fitment of the second outlet.

How much power does this add?

Fabspeed's dyno testing showed peak gains of 17whp and 13 ft-lbs of torque at 3900rpm.

Do I need to do anything after the first drive?

Yes, Fabspeed recommends retorquing all exhaust bolts to factory spec after the initial heat cycle to ensure a proper header seal.

What are the header collectors like?

Equal-length primary pipes feeding F1-style pyramidal investment-cast 3-into-1 merge collectors for better scavenging.

Which option should I choose?

Pick the Heat Exchange option that matches your car's year and displacement (1976-1983 3.0L, 1984-1989 3.2L, or without heat if you don't need cabin heat from the exhaust); add Sport Cats if you want to keep some emissions scrubbing, or leave them off and add the optional muffler bypass pipes for maximum weight savings and volume. 3.2L cars also need Fabspeed's OEM oil line kit for correct clearance, add it here if you don't already have it.

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.
