Borla® 60630 - Hot Rod 304 SS Pipe Kit (2.5" OD)

It’s easy to order a complete exhaust system when you can supply the usual make, model and year. But what if you have a custom car or a hot rod of your own creation? In the past you had to scrounge around at the local parts store, trying to find pipes and mufflers that would all fit together. And forget about performance or getting parts made of quality stainless steel!

Well those days are over thanks to Borla’s Universal Hot Rod Kit. Now you can get all the raw material Borla uses for its own systems so you can fabricate your own custom high performance, stainless steel 2 ½” exhaust system. You get 2 Turbo XL Mufflers, Two 5 ft. sections of stainless steel tubing, Four 45 degree bends, Four U-bends, Two 90 degree bends, Two 3” Phantom exhaust tips, and even 4 clamps and 4 universal hangers.

The patented straight through muffler design reduces restriction and increases exhaust gas velocity, making sure each cylinder is completely evacuated to make room for the incoming charge. This design absorbs the sound waves without disturbing the power waves, in contrast to the chambered mufflers used by most aftermarket companies. Chambered mufflers use partitions or baffles to subdue sound waves, which also creates backpressure and reduces power.

The shape and diameter of the exhaust tubing is optimized for volume and exhaust gas velocity. Borla mandrel bends the stainless steel tubing for smooth bends and to make sure the pipe maintains its size and shape throughout the entire length. Tubes that aren’t mandrel bent can lose a significant percentage of their diameter in sharp bends.

But improved performance is only part of what you want in an aftermarket exhaust system, because all the horsepower in the world won’t matter if it doesn’t sound right. There’s no need to worry with a Borla system. They have many years of automotive acoustical experience and the company is staffed with automotive enthusiasts just like you that listen and drive cars to make sure your system has the right sound to go with the power.

However, the best power and sound is meaningless if the exhaust system rots away in a few years. Borla uses the finest materials and construction techniques to make sure this won’t happen. They use austenitic stainless steel for their systems, which contains high levels of nickel and chromium, to resist corrosion. This material is harder than the lower grade stainless steel used by the OEM manufacturers, yet is very ductile. It can also be polished to a high luster, perfect for a custom car. The muffler contains a stainless steel perforated tube wrapped with several layers of stainless steel sound absorbing material and a layer of ceramic sound absorbing, high temperature material, all contained in a fully welded stainless steel shell.

Borla is so confident in the quality of this kit that it’s guaranteed against defects in materials and workmanship for one million miles.
