Titanium is significantly lighter than stainless steel at equivalent wall thicknesses, making this the correct exhaust for builds where weight reduction is a genuine performance priority. The exhaust note from a titanium system is sharper and more resonant than stainless — titanium rings at a higher frequency and produces a more distinctive character.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0737\/9029\/2257\/products\/03d48e2f259024e546134237ba88034f_e1208e11-6ce6-4238-b51c-66dcdfab559b.jpg?v=1697914856\" alt=\"Invidia Full Titanium Catback Exhaust - 2015-2021 Subaru WRX \/ STI\" style=\"width:100%;max-width:100%;margin:20px 0;border-radius:4px;\"\u003e\n\n\u003ch4\u003e\u003cstrong\u003eTitanium Throughout — Not Just the Tip\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThe distinction between the Full Titanium and a stainless system with titanium tips is significant — the entire pipe body, collector, and all connecting sections are titanium, not just the visible tip. The weight savings over a comparable stainless system are meaningful for a performance build, and the corrosion resistance of titanium exceeds stainless at the elevated temperatures the exhaust system operates at. CNC-machined flanges and OEM hanger positions retain the same bolt-in installation as the standard stainless cat-back.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0737\/9029\/2257\/products\/f9145625d621ac352fbef55e9f678d0f.jpg?v=1697914856\" alt=\"Invidia Full Titanium Catback Exhaust - 2015-2021 Subaru WRX \/ STI\" style=\"float:right;max-width:47%;margin:0 0 16px 16px;border-radius:4px;\"\u003e\n\n\u003ch4\u003e\u003cstrong\u003eBolt-In at OEM Hanger Locations, Premium Construction\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThe Full Titanium system connects at the OEM downpipe flange and hanger positions on the VA WRX\/STI — same installation as a stainless cat-back, different material throughout.

The sound character is different from stainless, not just louder — titanium produces a higher-pitched, more resonant tone that enthusiasts who have heard it either love or prefer stainless. It's worth listening to a sound clip of the titanium system before ordering if sound character matters to the build.\u003c\/p\u003e\n\n\u003ch4\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInvidia Full Titanium cat-back exhaust\u003c\/li\u003e\n  \u003cli\u003eTitanium exhaust tips\u003c\/li\u003e\n  \u003cli\u003eNew gaskets and installation hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003e\u003cstrong\u003eAbout Invidia\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eInvidia is a Taiwanese performance exhaust manufacturer with a strong following in the Subaru, Mitsubishi, and Japanese sports car communities. Their catalog covers cat-back exhausts, downpipes, headers, manifolds, and full exhaust systems built around SUS304 stainless steel construction with CNC-machined flanges and direct OEM fitment. Invidia exhausts are among the most widely installed aftermarket systems on Subaru platforms globally — well-documented, well-supported, and proven across thousands of street and track builds. Subispeed carries the full Invidia lineup because their combination of quality construction, fitment accuracy, and range of tip and finish options makes them the exhaust brand we recommend to Subaru owners at nearly every power level.\u003c\/p\u003e\n\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eYear\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eNotes\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e2015-2021\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eWRX\u003c\/td\u003e\n\u003ctd\u003eEJ255\/FA20DIT MT\/CVT\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e2015-2021\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eWRX STI\u003c\/td\u003e\n\u003ctd\u003eEJ257 MT\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Invidia","offers":[{"title":"Default Title","offer_id":45712098623574,"sku":"INVHS15SW4TRG","price":397.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/0411\/1190\/files\/7nbd4pay6gyk_f95e3cd4-2ccc-4dbf-97ab-1dc0b7a3c6d5.jpg?v=1788777639","url":"https:\/\/truegearus.com\/products\/invidia-full-titanium-catback-exhaust-2015-2021-subaru-wrx-sti-k06oxp","provider":"TrueGear","version":"1.0","type":"link"}
