Muffler seal ring — sourcing and pricing

Tags: #exhaust · #part-number · #price · #cross-compatibility

Symptom and dimensions: a disintegrated front muffler seal ring ("кольцо глушителя") causes the exhaust to roar/rattle loudly. The correct ring's parameters are 65 × 83 × 18 mm; this specific spec is associated with a Toyota cross-reference ¹².

Pricing — dramatic price gap between suppliers: the same ring is listed at 4,780 RUB on KitZap versus just 376 RUB on Ozon (RU market prices as of 2026-09-07/08) — over a 12x difference for what should be the same part ¹².

Cross-references: besides the Toyota-spec ring above, a "Mazda-type" ring is also commonly fitted by the community. The most popular cross-reference cited by message volume is SAT STL31540581 ³. ⚠️ Conflict: one owner disputes that the cheap 376 RUB/Ozon ring (RU market, September 2026) is genuine Toyota, calling it "явно не Тойота, а левак" (clearly not Toyota, a knockoff) — he notes that genuine Toyota muffler bolts cost 278 RUB each around 6 years prior (RU market, ~6 years before September 2026) (i.e. a non-trivial per-unit OEM price), and that he'd seen a genuine Honda ring listed around 12,000 RUB and a Mazda-spec ring around ~1,000 RUB (RU market, September 2026) (also likely non-original) — suggesting the true OEM/ cross-brand price tier is well above 376 RUB, and buyers should treat budget listings with some skepticism about genuine sourcing even when the physical fitment works ⁴.

Temporary and permanent field fixes: as a stopgap while sourcing a proper ring, 8mm basalt rope (шнур базальтовый) packed into the seal gap along with silicone sealant was reported as an effective temporary fix (the reporting owner had basalt rope on hand from his fireplace/chimney work). For a more permanent repair, the same silicone-sealed approach secured additionally with hose clamps was reported effective ¹.

Conical ring between the exhaust manifold and the resonator: alternatives and lifetime (Oct 2026). Victor 🇷🇺 says the standard ring is the one from the Mazda 6 GG ⁵. A member posted an Ozon listing SAT STL31540581, a muffler cone ring for the Honda CR-V 2007-2008, Civic, Mazda 3 from 2006 and Mazda 6 from 2008 ⁶; Victor 🇷🇺 confirms it is that part and calls SAT a budget brand ⁷, while Konstantin Руммель calls it rather junk ⁸. Victor 🇷🇺 says people do not bother and fit whatever is cheaper, most often the cheapest ZZVF ZVBZ0401; in his view 40-60 thousand km should be expected from such a ring, and a ring that costs five times more is not guaranteed to last 100 thousand ⁹.
