Nameless Performance Dual Exit Axle Back Exhaust (13+ BRZ)
Here it is, the Axleback for the 2013-2016 Subaru BRZ/Scion FR-S. These use dual 4" tips that fit the bumper nicely unlike the other exhausts out there with cartoon sized tips.
The Nameless axleback has a 2.5" or 3.0" inlet which is larger than stock but not too large. Both split the main circuit 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 3" inlet is intended for those looking to build a max hp N/A build, or going with some kind of forced induction. The 2.5" inlet is intended for the majority of people looking to keep the car N/A, and has a slightly quieter output than the 3"
