{"product_id":"high-flow-catted-downpipes-1","title":"High-Flow Catted Downpipes","description":"The JHMotorsport JHM-B8S4DPXCAT represents a pair of high-flow catted downpipes featuring an integrated baffle system, designed to enhance exhaust flow and performance for specific Audi models. These downpipes are engineered as a direct OEM replacement, facilitating an easy installation process with standard hand tools, eliminating the need for cutting or welding. The design strategically moves the high-flow catalytic converters downstream, which helps to mitigate heat buildup close to the engine, extending the lifespan of the catalytic converters and improving overall engine performance. This placement also allows for greater utilization of JHM's 2.5\" Race Pipes, contributing to increased low-end torque and maximized power across the entire RPM range.\n\nConstructed from T304 stainless steel, these downpipes incorporate a JHM V-Band connection for straightforward integration with the midpipe. Testing on a B8 S4 demonstrated that with the baffled downpipes, interior noise levels at 70 mph and 2500 RPM could be as low as 70db, significantly quieter than systems without the baffles.\n\nThis product fits all B8-B8.5 S4, S5, Q5, and SQ5 models, as well as C7-C7.5 A6 and A7 models equipped with 3.0T FSI engines. Purchasers must acknowledge and certify that their vehicle will be used solely for racing or off-road applications to comply with regulations such as Vehicle Code § 27156 and Health and Safety Code § 43000.","brand":"JHMotorsport","offers":[{"title":"Default Title","offer_id":52689709236536,"sku":"JHM-B8S4DPXCAT","price":1488.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687736883.jpg?v=1784909446","url":"https:\/\/store.motormia.co\/products\/high-flow-catted-downpipes-1","provider":"MOTORMIA","version":"1.0","type":"link"}
