The body has reinforcing ribs. It uses Borla's patented Multi-Core 4-tube internal design, which flows better than straight tubing for maximum flow, horsepower and torque, and is recommended for high horsepower applications. The reversible design adds installation flexibility. It is built from T-304 stainless steel with 100 percent welded construction and high-temperature T-304 stainless steel wool packing for sound control. The natural mill finish can be brushed or polished prior to installation, and there is no Borla logo embossment on this part. Borla exhaust products are handmade in the USA.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSystem type: Universal racing muffler, reversible\u003c\/li\u003e\n\u003cli\u003eCore: Patented Multi-Core 4-tube design\u003c\/li\u003e\n\u003cli\u003eInlet: 3 in center\u003c\/li\u003e\n\u003cli\u003eOutlet: 3 in center\u003c\/li\u003e\n\u003cli\u003eBody: 5.5 in x 8.5 in oval x 34 in long\u003c\/li\u003e\n\u003cli\u003eOverall length: 39.25 in\u003c\/li\u003e\n\u003cli\u003eMaterial: T-304 stainless steel\u003c\/li\u003e\n\u003cli\u003eConstruction: 100 percent welded\u003c\/li\u003e\n\u003cli\u003eAcoustic material: High-temperature T-304 stainless steel wool\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003cli\u003ePart number: 400115\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWill this muffler fit my vehicle?\u003c\/h5\u003e\u003cp\u003eIt is a universal muffler, not vehicle-specific.
