Borla S-Type Cat-Back Exhaust – 2019–2021 Genesis G70 3.3L V6 Twin Turbo | True Dual | Polyphonic Harmonizer | Million-Mile Warranty

The Borla S-Type Cat-Back Exhaust for the 2019–2021 Genesis G70 3.3L V6 Twin Turbo is a purpose-engineered true dual cat-back exhaust system delivering Borla's signature S-Type sound character — more aggressive and more expressive than the factory exhaust, with the rich, full-bodied exhaust note that the G70's twin-turbocharged Lambda II V6 deserves — without the interior drone that plagues lesser exhaust systems. Engineered specifically for the 3.3L G70, the system features a merge X-pipe for increased performance and improved sound, Borla's patented Polyphonic Harmonizer technology for a harmonically rich exhaust note, T-304 austenitic stainless steel construction, mandrel-bent piping, and Borla's industry-leading Million-Mile Warranty. The system exits through the factory OE valance openings — a clean, factory-integrated appearance with a dramatically improved exhaust character. Tips not included — reuse OE valance.

Key Features:

• Borla S-Type sound character — Borla's S-Type systems deliver a more aggressive, more expressive exhaust note than the factory system — the correct choice for G70 owners who want a noticeable, characterful exhaust upgrade without the excessive volume of a race-oriented system
• True dual cat-back system — 2.25" diameter true dual configuration — separate exhaust paths from the catalytic converters to the rear of the vehicle for maximum exhaust flow and the full dual exhaust sound character
• Merge X-pipe — X-pipe crossover between the dual exhaust paths — improves exhaust scavenging, increases performance, and contributes to the system's improved sound character compared to H-pipe alternatives
• Polyphonic Harmonizer technology — Borla's patented technology uses pipes of different diameters and lengths to create multiple exhaust notes that harmonize — delivering a clean, rich, full-bodied sound that is more complex and more musical than a single-note exhaust
• Zero interior drone — like all Borla cat-back systems, the S-Type is engineered to eliminate interior drone — the exhaust note is present and characterful outside the vehicle without the fatiguing resonance inside the cabin that affects many aftermarket exhaust systems
• T-304 austenitic stainless steel — premium T-304 stainless construction — superior corrosion resistance and durability compared to T-400 series (409) stainless alternatives used by lesser exhaust brands
• Mandrel-bent piping — ultra-smooth mandrel bends throughout the system — maximum exhaust flow and power compared to crush-bent alternatives that restrict flow at every bend
• OE valance exit — exits through the factory G70 OE valance openings — a clean, factory-integrated rear appearance
• Million-Mile Warranty — backed by Borla's industry-leading Million-Mile Warranty — the strongest warranty in the exhaust industry

Borla S-Type — Sound Character Explained:

Borla produces three primary exhaust sound levels for their cat-back systems — Touring (most refined, closest to factory volume), S-Type (performance-oriented, noticeably more aggressive than factory, the most popular choice for street performance builds), and ATAK (most aggressive, maximum volume, competition-oriented). The S-Type is the correct choice for G70 owners who want a genuine, characterful exhaust upgrade that is noticeably more expressive than the factory system in daily driving and spirited use — without the excessive volume that makes an ATAK system impractical for street use. The S-Type's Polyphonic Harmonizer technology ensures the exhaust note is rich and harmonically complex rather than a single harsh tone — a sound that complements the G70's premium character.

Polyphonic Harmonizer Technology:

Borla's patented Polyphonic Harmonizer technology uses a series of pipes of different diameters and lengths within the muffler assembly to generate multiple exhaust frequencies simultaneously — frequencies that are tuned to harmonize with each other rather than compete. The result is an exhaust note with harmonic complexity and richness that a simple straight-through or single-chamber muffler cannot produce — a sound that is full-bodied and musical rather than harsh or one-dimensional. Combined with the merge X-pipe's contribution to exhaust scavenging and sound character, the Polyphonic Harmonizer produces the distinctive Borla Sound of Power that has made Borla the most recognized exhaust brand in North American performance.

T-304 Stainless Steel — Why It Matters:

Borla builds every exhaust system from T-304 austenitic stainless steel — the same grade of stainless used in food processing, medical, and aerospace applications for its superior corrosion resistance and structural integrity. T-304 is significantly more corrosion-resistant than the T-400 series (409) stainless steel used by many competing exhaust brands — a meaningful difference in Canadian conditions where road salt, moisture, and temperature cycling accelerate corrosion on lesser materials. A Borla T-304 stainless exhaust system will outlast T-409 alternatives by a significant margin — which is why Borla can back every system with a Million-Mile Warranty.

• All required mounting hardware and gaskets
• Exhaust tips not included — system exits through and reuses the factory OE valance

Installation Notes:

• Professional installation by an experienced exhaust shop strongly recommended — true dual cat-back installation requires correct torque at the mid-pipe connections, correct hanger alignment, and verification of exhaust clearance throughout the system
• Use new gaskets at all connection points — reusing old gaskets risks exhaust leaks that affect performance and generate cabin odour
• Verify exhaust clearance from the body, chassis, and suspension components throughout the system after installation
• Allow the exhaust system to heat cycle several times before evaluating the final exhaust note — new exhaust systems can sound slightly different before the packing and seals have fully settled
• Check all connections for exhaust leaks after installation and after the first heat cycle
