REMARK 2022+ Subaru WRX VB Catback Exhaust - R1 Spec Single-Exit Full Titanium (Un-Resonated)

REMARK 2022+ Subaru WRX VB Catback Exhaust - R1 Spec Single-Exit Full Titanium (Un-Resonated) Single-Exit Full Titanium construction catback exhaust system Developed for those seeking a light weight high flow single exit exhaust system. This full Titanium system only weighs 16 lbs (w/ resonator), which is ~22 lbs. lighter than the OE exhaust. The R1-Spec features 3.0" mandrel bent piping, high flow straight through muffler, and 4.5" slant cut tip. The piping layout favors an optimal flow path to reduce the amount of restriction. Available with or without a resonator located on the midpipe. Select the resonated version to reduce the overall loudness of the system. Bolt-in silencer available separately in two internal pipe sizes. Mandrel Bent Piping, No Pie Cuts No 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. Point of Failure Most 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. Turbulence One 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.
