It does not replace the mid pipe or downpipes. Installation requires cutting the factory exhaust pipe at the second dimple on the OEM rear section, after which the IRL axleback clamps on without any welding. The extended exhaust brace for added clearance is included in the kit. The IRL V2 Valve Controller is strongly recommended alongside this axleback since the factory G8X exhaust valves only open to approximately 25-30% of their capacity. The valve controller, sold separately, allows you to open the valves to 100% on demand.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(255, 42, 0);\"\u003e\u003cstrong\u003eSpecs and Features\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eStainless steel construction throughout\u003c\/li\u003e\n\u003cli\u003eElectronic exhaust valves for factory-like operation, integrates with the existing G8X valve system\u003c\/li\u003e\n\u003cli\u003eFactory G8X exhaust valves only open approximately 25-30%, this system allows full 100% valve opening when paired with the IRL V2 Valve Controller\u003c\/li\u003e\n\u003cli\u003eFully clamp-on installation, no cutting or welding required\u003c\/li\u003e\n\u003cli\u003e100% reversible, stock exhaust can be reinstalled at any time\u003c\/li\u003e\n\u003cli\u003eExtended exhaust brace included for added clearance\u003c\/li\u003e\n\u003cli\u003eIRL tips included\u003c\/li\u003e\n\u003cli\u003eIRL V2 Valve Controller not included, sold separately, strongly recommended for full valve control\u003c\/li\u003e\n\u003cli\u003eDrone note: reducing muffler size from the OEM configuration increases the potential for drone, which is subjective and varies by driver.

The factory G8X valves only open to around 25-30%, and the controller gives you the option to push them to 100% on demand rather than being limited by the factory calibration.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA few things worth knowing before you order. Installation requires cutting the factory exhaust pipe at the second dimple on the OEM rear section. After that cut, the IRL axleback clamps on with no welding. If you plan to go back to stock at any point, keep the factory muffler section after removal so you have it to reinstall from the cut point. The factory G8X valves only open to around 25-30%, so IRL strongly recommends pairing this with the V2 Valve Controller. Without it the system still sounds better than stock, but you're leaving most of the upgrade on the table. The controller is sold separately. The extended clearance brace is included in the kit, so if you already bought the brace separately, check with us before ordering since you may already have one.\u003c\/p\u003e","brand":"IRL LLC","offers":[{"title":"Stainless Steel \/ Black","offer_id":42792158560336,"sku":"G80-AB-1B","price":1599.0,"currency_code":"USD","in_stock":true},{"title":"Stainless Steel \/ Stainless","offer_id":42792158593104,"sku":"G80-AB-1S","price":1599.0,"currency_code":"USD","in_stock":true},{"title":"Stainless Steel \/ Carbon","offer_id":42792158625872,"sku":"G80-AB-1C","price":1599.0,"currency_code":"USD","in_stock":true},{"title":"Stainless Steel \/ Burnt Blue","offer_id":42792158658640,"sku":"G80-AB-1B","price":1599.0,"currency_code":"USD","in_stock":true},{"title":"Stainless Steel \/ Raw Titanium","offer_id":42792158691408,"sku":"G80-AB-1B","price":1599.0,"currency_code":"USD","in_stock":true},{"title":"Titanium \/ Black","offer_id":42792158724176,"sku":"G80-AB-1B-1","price":1799.0,"currency_code":"USD","in_stock":true},{"title":"Titanium \/ Stainless","offer_id":42792158756944,"sku":"G80-AB-1B-2","price":1799.0,"currency_code":"USD","in_stock":true},{"title":"Titanium \/ Carbon","offer_id":42792158789712,"sku":"G80-AB-1B-3","price":1799.0,"currency_code":"USD","in_stock":true},{"title":"Titanium \/ Burnt Blue","offer_id":42792158822480,"sku":"G80-AB-1B-4","price":1799.0,"currency_code":"USD","in_stock":true},{"title":"Titanium \/ Raw Titanium","offer_id":42792158855248,"sku":"G80-AB-1B-5","price":1799.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0058\/0252\/4785\/files\/7FEAFB01-5185-4998-984F-9FE4383C604B.jpg?v=1784647791","url":"https:\/\/shop.redline360.com\/products\/irl-g80-g82-g83-v2-axleback-backorder-august-10","provider":"Redline360","version":"1.0","type":"link"}
