Our Exhaust Diffuser is both an aesthetic accessory and functional component. It does not change the acoustics of our exhaust and does not trap heat below the truck area.

The (4) subtle track-inspired fins are styled and positioned to compliment the factory valence elements. Our Exhaust Diffuser is finished in a neutral silver powder coat finish it is easily removed for those wanting to color match it to their vehicle.

The Exhaust Diffuser covers more surface area and is lighter than the transverse muffler it replaces. The benefit is reduced turbulence rear of the axle with no weight penalties. Our cat-back + Exhaust Diffuser combined is lighter than the factory cat-back! And there's no modification to any factory body panels as our exhaust diffuser mounts directly to our Borla cat-back exhaust PN-140496.

We've received positive feedback from track-intended owners and those looking for a subtle race-inspired accessory. It may not be for everyone but it only fits a Borla cat-back exhaust. Thanks again for your interest in Borla!

I am interested in this very much but I don't have a Borla exhaust or a factory one either. Was wondering if any1 has this with an aftermarket exhaust on. Thank you.

Hey guys
I just purchased a used scion frs. And the pervious owner installed a borla exhaust and rear diffuser. However since i got the car there is this really loud rattling noise coming from the car. Any thoughts?
