It has to seal a hot, pressurised exhaust joint while allowing the header and muffler to move relative to each other as the engine rocks on its mounts and the chassis flexes. A rigid joint there would simply crack, so the coupler absorbs that movement.\u003c\/p\u003e\u003cp\u003eThey are consumables. Heat cycling hardens them until they split, and once a coupler leaks the engine loses exhaust back pressure. That matters because a nitro engine relies on pressure from the exhaust to feed the fuel tank, so a leaking joint gives you a lean run, poor tuning that will not hold, and potentially engine damage. It also sprays oily residue across the chassis, which is usually the first sign you notice.\u003c\/p\u003e\u003cp\u003eTwo are supplied. Fitment is broad rather than model-specific: Kyosho lists this coupler across the DRX, DBX and DBX 2.0, DST, DMT and DRT, plus the V-One and Pure Ten 1\/10 nitro on-road range.\u003c\/p\u003e","brand":"PowerHobby","offers":[{"title":"Default Title","offer_id":44532855046232,"sku":"KYO92601BK","price":6.8,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0567\/0554\/8376\/files\/kyo92601bk_477df496-4816-45cd-b795-d8ed45dec86d.jpg?v=1786242827","url":"https:\/\/beavertonmilestonehobby.com\/products\/kyosho-92601bk-muffler-joining-pipe-black-2pcs","provider":"Beaverton Milestone Hobby","version":"1.0","type":"link"}
