They are designed to run the exhaust over the frame rails inside the fender wells. Tubing has been optimized for the Small Block Chevy 283\/302\/305\/307\/327\/350\/400 cubic inch engines. This creates a reduction in cylinder backpressure and improved exhaust gas velocity. These improvements free up lost horsepower and torque. An added benefit is a more performance-oriented exhaust sound.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMade of high quality T-304 stainless steel with computerized mandrel bends for strength and durability\u003c\/li\u003e\n\u003cli\u003ei.e. Maximizing smoothest high exhaust air flow rate\u003c\/li\u003e\n\u003cli\u003eTIG welded CNC machine flange\u003c\/li\u003e\n\u003cli\u003e2-Piece 4-1 Racing design(8-2-1)\u003c\/li\u003e\n\u003cli\u003eIncrease high flow air, instantly gain 10 to 15 Hp. \/ Tq.\u003c\/li\u003e\n\u003cli\u003eEngineered and Tested to Exceed Original Equipment Standards and Performance\u003c\/li\u003e\n\u003cli\u003eProfessional Installation is Highly Recommended (No Instruction Included).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cstrong\u003e  Fitment:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFits Chevy small block 265-400 V8 engine\u003c\/li\u003e\n\u003cli\u003eFits 1935-1948 fat fender well street rod and pickup application\u003c\/li\u003e\n\u003cli\u003eFits most angle plug heads\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"XKVracing","offers":[{"title":"Default Title","offer_id":47887661007018,"sku":"XKV11077","price":180.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0690\/9506\/3722\/files\/0_0085_MT001027-EH28124-11077SAS_Main_lmage.webp?v=1769762219","url":"https:\/\/xkvracing.com\/products\/1935-1948-chevrolet-small-block-exhaust-headers-stainless-steel-tri-y-design-fits-216-235-261-inline-6-engines-bolt-on-installation-pre-1954-chevy-cars-trucks","provider":"XKVracing","version":"1.0","type":"link"}
