3" Header-Back Exhaust - 2017-2021 BRZ/GT-86

Here it is, the street package for the 2017-2021 Subaru BRZ/Toyota GT-86. This package includes our Dual Exit 3" Axleback, 3" resonated midpipe, and our 3" High Flow Cat Downpipe with resonator. Bundling these this way saves significantly on shipping.

This exhaust is intended for people who have forced induction planned for their car, or for owners who are staying N/A and want every last drop of power you can wring from the exhaust.

*Disclaimer: this exhaust will be loud with no turbocharger*

Performance
The 3" Overpipe/Downpipe Combo replaces both the overpipe and the downpipe, thereby opening up the connection between the header and the catback exhaust.    Ideal for high horsepower naturally aspirated and forced induction vehicles, the 3" diameter has netted the highest numbers on all of our forced induction and long tube header development vehicles.  From a turbocharged perspective, the net gains on a 3" exhaust vs. the factory diameter are quite substantially, often netting upwards of 50ft lb of torque over factory exhaust diameters.  For naturally aspirated vehicles running our long tube 4-2-1 Header and factory intake manifold, gains as high as 49ft lb at the wheels have been seen with the full 3" exhaust and tune. 

Specs
Featuring mandrel bent T304 stainless TIG welded construction and gusseted hanger, this design is a must have for those enthusiasts wanting to get the most power out of their BRZ / 86 / FR-S. Utilizing an SCCA legal 200 Cell catalytic converter and a 3" straight through design resonator allows us to reuglate tone and keep it emissions friendly. At the aft end of the overpipe/downpipe, a 3" donut gasket is used to connect the outlet to any 3" midpipe.  A flat gasket can be arranged if the catback exhaust is a flat flange or reduced diameter.  Make sure to let us know what you're attaching the part to so that we can send the appropriate parts.

This product is not compatible with the AT transmission.

Our axleback has a 3" inlet which is larger than stock but not too large. The 3" main circuit then splits to two 2" pipes. Both 2" circuits terminate in 4" diameter tips that sit flush with the bumper. This makes the car look like it should have from the factory.

The weight of our axleback is 17 pounds compared to the 25 pound stock muffler.

The axleback produces almost no peak HP but fills in the valley that is typical of this new direct injected boxer 4.

Muffler Options:

• No Mufflers
• 5" Mufflers

Recommended Add-Ons:

Exhaust Hanger Bushings

Upgrading to our long lasting Nameless Performance urethane exhaust bushings from the factory rubber bushings is highly recommended. The softer rubber factory bushings are overly flexible and if you race your car or spend time at an incline off-road, the exhaust can "wag" left to right which sometimes causes noise or the tips to touch the rear bumper. When this happens there is a chance your bumper can be damaged or if you have a hitch or any other accessories can cause annoying sounds. The best way to avoid this is to use our urethane exhaust bushings to hold the exhaust in place. These upgraded bushings are not necessary to install our exhaust systems but for the small cost of upgraded units, it is an excellent idea!

• Add 2 Bushings to your cart: Replace the two bushings at the rear of the car closest to the bumper. Recommend for those who either drive hard on the street or race occasionally at the track.
• Add 4 Bushings to your cart: Replace all 4 rubber bushings on the axleback portion of the exhaust. Recommended for people drive off-road or who race their cars often.
• Add 5 Bushings to your cart: Replace all 5 of the factory rubber bushings from the midpipe back. Recommended for those who are hard core off-raoders, autocrossers or circuit racers.
