Product Details

The Kooks KO300-12-CI is a 3-inch oval clamp-in muffler built for high-performance street, strip, and off-road exhaust systems. Featuring a center inlet and center outlet configuration, this muffler slips directly over 3-inch tubing and secures with included clamps — no welding required. The polished T304 aircraft-quality stainless steel construction delivers exceptional corrosion resistance and a show-quality finish that holds up under extreme heat and use.

Key Features:

  • 3" I.D. Center Inlet / Center Outlet — slip-fit design slides over standard 3" tubing
  • 12" Long Body with 16" overall length
  • 4-1/2" x 7-1/2" Oval Body for a low-profile fitment
  • Polished T304 Aircraft-Quality Stainless Steel construction throughout
  • Clamp-In Installation — includes 2 JI-TAS300 clamps; welding not required
  • Dyno and race tested design optimized for maximum power output
  • Handcrafted in the USA at Kooks' facility in Statesville, NC
  • Limited Lifetime Warranty to the original purchaser
  • Sold individually

Kooks Headers and Exhaust has been a leader in the high-performance exhaust industry since 1962, with proven results across NHRA, IHRA, NMCA, NMRA, NASCAR, NASA, SCCA, and more. The KO300-12-CI is a direct reflection of that racing heritage — precision-built, durable, and engineered to flow.

Easy, order & receive

I am very pleased with my purchases from Boatplicity. They had some hard-to-find items in stock and delivery was prompt.

Quick and fast

Thank you for this item at this price.

No problems

Only issue was lack of shipping confirmation, no order update and the unit showed up at my house in a full size 18 wheeler :)

GOOD EXPERIENCE SO FAR, WILL WAIT FOR DELIVERY & UPDATE.

Thanks for the fast delivery
