Borla Universal 3-Inch Inlet to 4.25-Inch Outlet Polished Stainless Steel Single Round Rolled Angle-Cut Intercooled Exhaust Tip (20251)
Transform the rear profile of your vehicle with the mirror-polished look of the Borla Universal Single Round Rolled Angle-Cut Intercooled Exhaust Tip. Masterfully engineered to fit high-flow standard 3-inch outer diameter tailpipes, this high-impact performance upgrade transitions cleanly into a bold, oversized 4.25-inch round outlet diameter. Featuring a premium rolled edge with an aggressive slant-cut exit and a specialized intercooled breath-ring barrel, this styling asset contours naturally with your rear body styling while building a distinctive structural visual depth unique to the industry. Formulated explicitly for performance enthusiasts, custom fabricators, and street machine builders who demand a flawless rear-valance presentation, this premium exhaust tip introduces a sharp styling asset that immediately accents clean bumper lines, tight rear clearances, or custom dual-exhaust setups.
The internal engineering of the Borla 20251 targets key installation and durability problems by incorporating an upgraded, high-efficiency weld-on configuration. Engineered explicitly for a permanent, leak-free fusion, this premium layout slips over or butts against your existing exhaust pipe section, allowing professional installers to achieve a perfectly flush, rattle-free installation under heavy structural vibrations. At its core, the ultra-compact 4-inch overall length provides a highly adaptable layout that fits neatly into tight rear bumper spaces, making it perfect for applications where extended length tips would stick out too far or hit chassis components, while showcasing the iconic embossed Borla logo on the polished top shell. Built completely from aircraft-quality, premium-grade T-304 austenitic stainless steel finished in an authentic high-gloss mirror shine, this highly durable styling component permanently defends against structural degradation, surface pitting, and severe under-car heat discoloration. Precision-crafted with seamless high-strength welds and an ultra-smooth bright polished reflective surface finish, this luxury hardware add-on delivers long-lasting structural defense backed by Borla’s legendary Million-Mile warranty.
Distinguished Intercooled Rolled Slant Architecture: This premium single round tip features a thick rolled-edge, angle-cut styling configuration that focuses exhaust notes cleanly out the back while adding a muscular, heavy-walled visual appearance. The specialized inner intercooled louvers enhance the visual depth of the 4.25-inch opening, pulling in ambient air to cool the outer barrel casing. This functions as an excellent heat-dissipating shield that helps safeguard surrounding plastic bumper inserts, composite valances, and fiberglass body panels from melting, disfiguring, or accumulating heavy soot buildup under sustained high-load driving runs.
Fabrication Installation Guideline Note: This performance tip features a professional weld-on install type. Unlike loose-fitting clamp-on choices, this permanent join method completely eliminates the risk of hardware backing off or stripping over time, providing clean visual lines and permanent peace of mind on track-driven or modified street vehicles.
