Invidia HS12SSTGTT N1 Cat-Back Exhaust System

Manufacturer

Invidia

<h3>Invidia: Race-Proven Performance Exhaust Engineering</h3><p>Few names in the aftermarket performance world carry the weight that Invidia does among sport compact enthusiasts. <strong>Invidia</strong> got its start supplying exhaust systems to race teams, and that motorsport DNA is baked into every product they produce. <a href="/905-invidia-exhaust-system-kit-10727">Invidia exhaust system kits</a> quickly earned a loyal following among tuners, and the brand eventually began selling to the general public — a move that brought race-bred technology to street cars around the world.</p><p>Originally manufactured in Taiwan on behalf of the Japanese tuning company RS-R, the Invidia brand was later acquired by Jetworld/Jetstar Auto Sports Inc. of Southern California. Today, Invidia continues to develop and distribute products out of that base, and their lineup has grown to cover vehicles from Subaru, Mitsubishi, Honda, Toyota, Nissan, Volkswagen, and more.</p><h3>Built for Performance, Built to Last</h3><p>What separates Invidia from budget-oriented competition is their commitment to materials and manufacturing precision. <a href="/905-invidia-exhaust-system-kit-10727">Their exhaust system kits</a> are constructed from Grade 304 stainless steel, a corrosion-resistant alloy that stands up to heat cycling and harsh climates far better than mild steel alternatives. For enthusiasts seeking the ultimate in weight reduction and aesthetics, Invidia also offers a premium titanium line — delivering the exotic look and featherweight properties that serious builds demand.</p><p>Production relies on mandrel bending and precision jig-based tooling, meaning every bend maintains consistent pipe diameter throughout its arc. The result is reduced exhaust backpressure, improved scavenging, and measurable gains in both torque and horsepower — without sacrificing the low-end grunt that makes a street car driveable every day.</p><h3>Signature Product Lines</h3><p>Invidia&apos;s two most celebrated exhaust families are the <strong>N1</strong> and the <strong>Q300</strong>. The N1 is a race-inspired, more aggressive-sounding system popular with track-day enthusiasts, while the Q300 uses a continuous-piping muffler design and Advantex material for a deeper, more refined tone that suits daily drivers. Both lines include flat-bottomed muffler designs engineered to preserve ground clearance and improve undercarriage aerodynamics.</p><p>Beyond full cat-back systems, Invidia makes a comprehensive range of supporting components. Their <a href="/905-invidia-turbocharger-up-pipe-14153">turbocharger up-pipes</a> are a go-to upgrade for turbocharged Subaru WRX and STI owners looking to improve turbo spool and throttle response. And for completing a full exhaust build, Invidia&apos;s <a href="/905-invidia-exhaust-intermediate-pipe-11125">exhaust intermediate pipes</a> — including straight mid-pipes and resonated options — allow tuners to fine-tune the sound and flow characteristics of their setup. Together, these components form a cohesive, well-engineered exhaust solution from manifold to tip.</p><h3>A Brand Trusted by the Tuning Community</h3><p>Whether you&apos;re building a dedicated time-attack car or simply want to wake up a daily driver, Invidia&apos;s depth of fitment and quality of construction make them one of the most respected names in performance exhaust. Their products have received ECE/ABE certification approvals after thorough assessment by German Government KBA testing, underscoring the brand&apos;s commitment to engineering standards that go beyond the track.</p>

I called the same day to change my shipping to receive my part faster and was told no changes to my order could be made. The part was ordered on a Friday and was not shipped till Tuesday . I seriously don't understand why a change could not be even checked on. Just received a hard 'no changes' statement. I would say everything else was great with purchase.

I got this item for a friend and I have no details on anything other it was shipped fast.

Great shopping with them. The order ever came in two days faster than they said. Now that's speedy service!
