{"product_id":"3-inch-304-stainless-steel-downpipe-2","title":"3-Inch 304 Stainless Steel Downpipe","description":"The Pope Engineering Performance (PEP) Mazdaspeed Protege downpipe is a 3-inch exhaust component designed to replace the stock \"S\" and \"J\" pipes, offering a one-piece, robust design and construction. Fabricated entirely from 304 stainless steel, this includes the casting, tube, flange, and flex, ensuring durability. The casting boasts a substantial 4.5 mm wall thickness for exceptional strength.\n\nInstallation of this downpipe requires only one modification: the removal of the tab on the AC compressor. The kit includes a hardware kit with a 3-inch exhaust gasket and necessary bolts, along with a thermostat spacer. This aluminum 1\/2-inch thick spacer is designed to adjust the water neck clearance, accommodating the stock lower radiator hose and coming with gaskets and hardware. An optional upgrade to the SpeedCircuit Thermostat Outlet kit offers a more refined solution with a new silicon radiator hose.\n\nWhile it can be installed with a stock midpipe, this is not recommended due to the potential for leaks and installation difficulties. For optimal results, it's advised to tighten exhaust flanges from front to back to ensure proper alignment and prevent leaks at the downpipe to midpipe connection. Following installation, a test drive is recommended to check for boost spikes, which can occur due to faster turbo spooling and may require vacuum line rerouting. Ensure the swing valve does not contact the downpipe; if it does, porting the downpipe inlet may be necessary.","brand":"Pope","offers":[{"title":"Default Title","offer_id":52689332994360,"sku":"PEP_MSP_DP-01","price":469.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687483907.webp?v=1784905294","url":"https:\/\/store.motormia.co\/products\/3-inch-304-stainless-steel-downpipe-2","provider":"MOTORMIA","version":"1.0","type":"link"}
