Constructed entirely of titanium, it weighs just 17 lbs (including the resonator), making it approximately 22 lbs lighter than the original equipment (OE) exhaust. The R1-Spec features 3.0-inch mandrel-bent piping, a high-flow straight-through muffler, and a 4.5-inch slant cut tip. The piping layout is optimized for maximum flow, minimizing restrictions. The system is available with or without a resonator located on the midpipe. Choose the resonated version if you wish to reduce the overall loudness. Additionally, a bolt-in silencer can be purchased separately, available in two internal pipe sizes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMandrel Bent Piping, No Pie Cuts\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo unneeded pie cuts with our systems. Many enthusiasts like the look of pie cuts but in our opinion the aesthetic is not worth the potential for failure, and added exhaust gas turbulence. The use of pie cuts was a solution to create a bend when bending is not an option or the bend radius is too tight. For most front engine, rear exit exhaust systems, there is no need for pie cuts. Our experienced staff and CNC mandrel benders are able to bend a single pipe with multiple mandrel bends.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePoint of Failure\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMost exhaust system failures happen at the welds regardless of the material. Each additional weld for the pie cut bend is a potential point of failure. Failure at the weld can be caused by: contamination of the materials, poor fitment of components, improper welding technique, poor gas coverage, too little heat, too much heat, welded too fast, welded too slow, and the list goes on. So many different things have to be executed properly to obtain a strong weld. We do not see a point of unnecessarily increasing risk of failure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTurbulence\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOne of the main reasons to change to a performance exhaust is for increased power which is achieved by improving the flow of exhaust gases. A single mandrel bend is smoother and stronger than using multiple pie cuts to form the same angle bend. Each weld creates turbulence as the surface is not smooth. Think of the Winter Olympics and the downhill luge. The course is a series of smooth turns in both directions as well as elevation changes like the piping of an exhaust system. Imagine if each bend was made of pie cuts, each weld would be a bump. If you were a competitor, would you rather take the smooth course or the one compromised of mini bends and tons of bumps.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe title=\"REMARK R1-Spec Full Titanium Catback Exhaust with resonated midpipe - 2015-2021 Subaru WRX\/STi (VA)\" src=\"https:\/\/www.youtube.com\/embed\/KR9OZ1YIE30\" height=\"554\" width=\"900\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubaru WRX STI \u003c\/strong\u003e(2015, 2016, 2017, 2018, 2019, 2020, 2021)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable height=\"346\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eExhaust Type \u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eCatback exhaust 3pc design\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePiping Diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eFull 3inch piping\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTip Diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eSingle 4.5 inch slant cut tip with laser engraved logo\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMidpipe Material\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHigh-grade Titanium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMuffler Material\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eHigh-grade Titanium\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMuffler Tip Material\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eHigh-grade Titanium\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWelding \u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHand crafted high quality tig welding\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eShipping Dims\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ew\/o Resonator - 54x19x9\" , 26 lbs.\u003cbr\u003ew\/ Resonator - 54x19x9\" , 28 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Remark","offers":[{"title":"Default Title","offer_id":51729362256186,"sku":"remRK-C1076S-01TF","price":1859.23,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0025\/9709\/3420\/files\/3d88dde4d16e3f7927dcce9a53dc062eL.jpg?v=1755099735","url":"https:\/\/www.kamispeed.com\/en-ca\/products\/remark-15-21-subaru-wrx-sti-r1-spec-cat-back-exhaust-single-exit-full-titanium","provider":"KamiSpeed.com","version":"1.0","type":"link"}
