FAQ
What vehicles does the Borla 11944 fit?

What tip does it use?
The system uses a single 3.5in by 2.75in polished T-304 stainless steel tip.
Is this Borla exhaust street legal?
Borla classifies this as a street rear-section system and publishes that its street cat-backs, rear sections, and mufflers are 50-state emissions legal. It mounts behind the factory catalytic converters and removes no emissions equipment, so confirm legality for the specific model year and state before purchase.
How does the S-Type sound compare to ATAK?
S-Type delivers an aggressive classic Borla tone with no interior drone. ATAK is Borla's loudest street tier, so S-Type sits one step below ATAK in volume while staying more aggressive than the Touring level.
