Description
The 2001-2006 Audi TT Quattro 1.8T 225HP SS has a distinct performance identity, and this Borla setup is designed to make the exhaust note better match that character. Compared with leaving the corresponding factory section untouched, this cat-back exhaust system reworks the exhaust downstream of the catalytic-converter section for a broader change in tone, flow character, and rear-of-car presentation.
It is a strong fit for an owner who wants the exhaust upgrade to feel complete—sound, visible finish, and the character of the system behind the catalytic-converter section—rather than changing only the rear mufflers. In practice, this product is best suited to owners who want to bring more mechanical character to a performance-oriented luxury platform while retaining a finished, vehicle-specific presentation.

About Borla
A long-established name in performance exhaust, Borla focuses on engineered sound as much as hardware—developing systems around individual vehicle applications rather than relying on a universal approach. That background makes this product a natural choice for a build where exhaust tone and fitment matter as much as simply replacing factory hardware.
Fitment note: Confirm model year, engine, trim, factory exhaust equipment, and the selected Borla part number before ordering.
