Borla S-Type Cat-Back Exhaust

Borla does not promise one universal gain because the result depends on the vehicle, engine, and exact system. A cat-back can reduce restriction, but claims such as an automatic 5 to 10 hp increase should be confirmed with testing for the specific application.

S-Type is Borla's middle sound level: more aggressive than Touring but less extreme than ATAK. The final volume and cabin drone still depend on the vehicle, engine, resonators, and cruising speed.

Borla commonly constructs its cat-back systems from T-304 austenitic stainless steel, including tubing, mufflers, and tips where specified. "Series II stainless" is not the usual material designation in Borla's current product literature.

No. A cat-back system replaces exhaust components downstream of the catalytic converter, so it normally leaves factory emissions equipment intact.
