{"product_id":"axle-back-exhaust-w-mufflers","title":"Axle Back Exhaust w\/ Mufflers","description":"The REMARK Axle Back w\/ Mufflers is a high-flow exhaust system specifically engineered for the 2022-2025 Lexus IS500. This axle-back system replaces the OE mufflers, offering an aggressive deep tone and distinctive slant quad tip styling tailored for the IS500. The exhaust sound is designed to blend with the V8's induction noise, allowing the glorious sounds of the 5.0L engine to remain audible. From startup to approximately 2500 RPM, the exhaust provides a dominant low grumble. As the RPMs increase and during cruising, it becomes a subtle background sound, allowing for easy conversation and audio system enjoyment. When the throttle is engaged, the V8 engine's induction noise becomes primary, mixed with the exhaust note.\n\nConstructed from full 304 stainless steel with TIG-welded seams, this system features 2.5-inch, 16-gauge mandrel-bent piping and 4-inch diameter slant-style tips. The mufflers are of a straight-through design to maximize exhaust flow while controlling sound levels, achieving a balance that complements rather than overpowers the vehicle. The axle-back kit is available in two tip finish variants: a fully polished Stainless Double Wall and a Burnt Stainless Double Wall, which features a spectrum of colors achieved through a chemical process.\n\nThis exhaust system is a simple, direct bolt-on replacement for the factory mufflers, requiring no modifications and not triggering check engine lights or affecting vehicle emissions. Installation is straightforward, with no cutting or welding needed, and the factory exhaust can be easily reinstalled at any time. The kit includes both right and left side components, along with the necessary hardware. The system utilizes factory donut gaskets and spring bolts for mounting to the factory midpipes.","brand":"REMARK","offers":[{"title":"Default Title","offer_id":52664201609528,"sku":"RM-IS500-A","price":1295.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/686899464.webp?v=1784335089","url":"https:\/\/store.motormia.co\/products\/axle-back-exhaust-w-mufflers","provider":"MOTORMIA","version":"1.0","type":"link"}
