All of our products are made in the UK and distributed to more than 90 countries worldwide, making Milltek Sport one of the most accessible performance aftermarket brands on the market. Our catback design includes all sections to replace the factory exhaust tips, mufflers, and resonator up to the midpipes. Enjoy an unrestricted system that delivers the perfect exhaust note from your turbocharged V6 engine. A catback exhaust system replaces the muffler and tailpipe with a more free-flowing design. This allows the exhaust gases to flow more easily out of the engine, which can improve the sound and performance of the vehicle.

Glasspack mufflers do not have extra sound-absorbing material. So, in order to absorb sound, they use the glass layer and packing. But if you are making your order on partcatalog.com, you can always inquire about the recommended tube diameter for your exhaust system by providing your make and model. This can lead to a significant decrease in torque and horsepower as well as rpm.

The new Large Bore-HD exhaust is engineered to perform in the most extreme environments. This system is constructed from mandrel bent 4" stainless steel tubing for maximum flow, increased horsepower, increased torque and lower EGT's. This system is available in 4" cat-back with muffler. Large Bore-HD exhaust systems are the perfect combination of performance, fit and value. For over 40 years, MagnaFlow has maintained its position at the forefront of high-end catalytic converter and performance exhaust manufacturing. MagnaFlow stands by its products with industry-leading warranties in service of its mission to provide the highest quality exhaust experience from start to finish.

You also need to be careful when tightening the bolts on the cat back. Over-tightening can damage the system, so just make sure they're tight enough to hold everything in place. It's important to make sure that the cat back is properly aligned with the exhaust pipe. If it's not, you could end up with an inefficient or even dangerous exhaust system. Competitors often rely on generic silencers or gimmicks that claim to cut out drone without any real knowledge or development involved.
