Unlike other manufacturers, BOOST Products focuses on high quality (grade standard). Especially for titanium products in exhaust systems, it is absolutely necessary to use at least Grade 2 quality standard.\u003c\/p\u003e \r\n\r\nDue to its special material properties, titanium is an ideal material for the construction of exhaust systems, downpipes, or charge air pipes in motorsports. A very low weight combined with high tensile strength allows the use of lower material thicknesses, so the metal naturally weighs less than steel and in many ways just as robust. It is not unusual for a complete titanium exhaust system to weigh less than 7lbs.\u003cbr\u003e \r\n\r\n\u003ch3\u003eKey benefits and features\u003c\/h3\u003e\r\n\u003cli\u003e1.2mm wall thickness\u003c\/li\u003e\r\n\u003cli\u003eGrade 2 titanium \u003c\/li\u003e\r\n\u003cli\u003eUltra lightweight\u003c\/li\u003e\r\n\u003cli\u003eExcellent for heat management\u003c\/li\u003e\r\n\u003cli\u003eWeld ready, comes pre-prepped\u003c\/li\u003e\r\n\u003cbr\u003e\r\n\r\n\r\n\u003c!-- **************************** --\u003e \u003ctable cellspacing=\"0\" cellpadding=\"4\"\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd colspan=\"6\"\u003e\u003cstrong\u003eWeight Chart - Titanium short elbow\u003c\/strong\u003e\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003eID (inches)\u003c\/td\u003e \u003ctd valign=\"top\"\u003eWeight (lbs)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e2\" \u003c\/td\u003e \u003ctd\u003e0.66\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e2.5\"\u003c\/td\u003e \u003ctd\u003e1\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e3\"\u003c\/td\u003e \u003ctd\u003e1.2\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e3.5\"\u003c\/td\u003e \u003ctd\u003e1.4\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e4\"\u003c\/td\u003e \u003ctd\u003e1.8\u003c\/td\u003e  \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003c!-- **************************** --\u003e\r\n\r\n\u003ch3\u003eWhen you should use a flex bellow?\u003c\/h3\u003e\r\n\u003cp\u003eA bellow is a specific type of joint that helps with thermal expansion and should be used when there is a heavy amount of heat cycling. Anything like wastegate pipes or downpipe attachements to the manifold are common areas to place a flex bellow. Add a bit of flare and weight savings to your build by using a BOOST titanium bellow!\u003c\/p\u003e\r\n\r\n\u003ch3\u003eHow hard is it to weld titanium?\u003c\/h3\u003e\r\n\u003cp\u003eTitanium is one of the harder metals to work with when it comes to welding. You'll need to TIG weld here and a 100% Argon purge is recommended to avoid atmospheric contamination. This is important because if not done properly, this causes cracking and ends up failing sometimes easier than steel. In our experience, fabricators say you should use ERTi-2 filler rod for any Grade 2 titanium.\r\n\r\n\u003c\/p\u003e\u003ch3\u003eDo I really save that much in weight?\u003c\/h3\u003e\r\nIt is actually quite considerable the amount of weight saved when it comes to titanium vs. steel. On average, titanium can weight about 45% less than their 304\/316 stainless steel counterparts. For reference, our titanium elbows all weigh less than a single pound - that's less than the weight of a single loaf of bread!\r\n\r\n\u003ch3\u003eGrade 2 vs Grade 5 titanium\u003c\/h3\u003e\r\nGrade 2 titanium is the type you see the most when it comes to commercial sales. They are found in exhausts, piping and even some checmical equipment. For those wanting high quality metal that is rust resistant and offers plenty of tensile strength, you'll see most using Grade 2. Grade 5 is more for aerospace, aircraft turbines, high strength valves and other complex systems. They have a much higher tensile strength but is not for the casual DIYer. They are extremely difficult to weld with, does not form well and are extremely difficult to machine.\r\n\r\n\r\n\u003ch3\u003eSome things to consider\u003c\/h3\u003e\r\n\u003cli\u003eIf you are looking for a more flexible joint, please take a look at our steel exhaust flex pipe, they have are a bit more forgiving and malleable to movement and vibration.\u003c\/li\u003e\r\n\u003cli\u003eWe use grade 2 titanium for our line of titanium piping products. Grade 2 is the most commonly commercialized version of the types of titanium we see on the market. It's the main industry go-to standard for exhausts, downpipes or intake plumping.\u003c\/li\u003e\r\n\u003cli\u003eWhile the result could be visually stunning, we recommend you have experience as a fabricator before undertaking a titanium welding project. They are not the easiest metal to work with - nor is it the cheapest. They are less forgiving when it comes to how it's welded, they can crack easier than steel if the welds are not done properly.\u003c\/li\u003e\r\n\u003cli\u003eThe discoloration after heat is put through it is normal and often the reason some even use titanium.\u003c\/li\u003e\r\n\u003cli\u003eTitanium has a different resonance than steel, so the sound will be quite different over building an exhaust system using steel.\u003c\/li\u003e\r\n","brand":"BOOST Products USA","offers":[{"title":"2\" (51mm)","offer_id":42923929632853,"sku":"EX-KO-TI-51","price":180.0,"currency_code":"AUD","in_stock":true},{"title":"2.5\" (63.5mm)","offer_id":42923929665621,"sku":"EX-KO-TI-63","price":201.0,"currency_code":"AUD","in_stock":true},{"title":"3\" (76mm)","offer_id":42923929698389,"sku":"EX-KO-TI-76","price":217.0,"currency_code":"AUD","in_stock":true},{"title":"3.5\" (89mm)","offer_id":42923929731157,"sku":"EX-KO-TI-89","price":233.0,"currency_code":"AUD","in_stock":true},{"title":"4\" (102mm)","offer_id":42923929763925,"sku":"EX-KO-TI-02","price":291.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0947\/5040\/files\/var-ex-ko-ti-1-140566.jpg?v=1787889547","url":"https:\/\/speedzone-web.com\/en-au\/products\/titanium-exhaust-flex-joints-bellow-grade-2","provider":"Speedzone Performance LLC","version":"1.0","type":"link"}
