A dual 3” T304L stainless steel downpipe-back configuration, the AWE Touring Edition Exhaust is perfect for drivers looking for straight-pipe performance withpout sacrificing daily drivability: a deep, sophisticated exhaust note with zero drone at highway speeds. Featuring a stamped stainless steel merge upstream equivalent to dual 3” tubing coming right off of the downpipe. Translation: an impressive 65% increase in flow over stock that future proofs for downpipes of various sizes. The Touring Edition features AWE’s patented drone-canceling solution, 180 Technology®, which targets & omits drone-prone frequencies. If you're equipping an aftermarket downpipe with an outlet larger than 80mm, we've made it easy for you. Removal of the included inlet adapter will be required, leave the 3.5" diameter inlet of the stamped stainless steel merge. A simple custom adapter will be required to mate your aftermarket downpipe & the 3.5" diameter inlet of stamped stainless steel merge. We've future-proofed your exhaust for big power with no less than 3.5" of high-flow fury. AWE does not offer aftermarket downpipes. Aftermarket downpipes that affect emissions devices are for racing use only. The Touring Edition Exhaust is available as non-resonated or resonated. We recommend the non-resonated variant for vehicles with the stock downpipe for the perfect full-bodied exhaust note complete with strong pops & burbles when in sport mode. If your Supra is has an aftermarket downpipe, we recommend going resonated to help control the rasp introduced from that downpipe. Want to run resonated with the stock downpipe? Perfectly fine. Drivers can expect a deep, sophisticated exhaust note when paired to the stock downpipe. Pops & burbles will be slightly softer when in sport mode. Stock downpipe but planning to go aftermarket later? The AWE Resonator Conversion Kit is here when ready.
