Exhaust stacks are the hottest item in the diesel performance aftermarket. Diesel exhaust stacks look great and are functional. In this Article I will attempt to address the functionality of truck exhaust stacks and the different variations of truck exhaust stacks that are available. First I will address the main companies making exhaust stack systems.

MBRP Inc. is the manufacturer of the MBRP Smokers exhaust stacks. The MBRP Smokers exhaust stacks were designed to give the aggressive Big Rig look and the classic MBRP sound. MBRP has both turbo back exhaust stacks systems and universal bed kits that go through the bed and connect onto the stock exhaust system offering the look at a reasonable price. Both the turbo back exhaust stack system and the universal “T" Pipe bed kit are made of stainless steel. The Turbo back exhaust stacks are mandrel bent and will give maximum exhaust flow, fuel mileage gain, power increase, and minimize the EGT’s. The diesel exhaust stack “T" pipe bed kits are more for looks, although there still will be a performance gain. MBRP offer 4, 5 and 6 inch exhaust stacks and have the options of a straight cut, mitre or angle cut, a curved end or turn out tip, and bull hauler stacks. These stack variations come in either 36 inch or 48 inches long. There is also an aluminum checker plate cover over the “T" pipe in the bed, it give a nice complete finished look and will keep the hot “T" pipe from touching anything.

Grand Rock truck exhaust systems make chrome exhaust stacks for trucks and big rigs. Chrome exhaust stacks are also very durable and have the mirror finish that many look for. Grand Rocks Chrome exhaust stacks come in 3, 4, 5, 6 and 7 inch sizes. Grand Rock also offers their chrome universal Powerflow “T" pipe bed kit for those who are just looking for the big rig look and a small performance gain. They also offer a turbo back chrome exhaust stack system for those looking for all out performance and looks. Chrome exhaust stack systems are very durable and are a lot less expensive. Chrome exhaust stacks look great and are a great value.

Most people that buy truck exhaust stacks have them for either looks or performance gains and maximum exhaust flow. Some though have exhaust stacks for functional reasons. Imagine having a flatbed that you use to haul things day in and day out. Wouldn’t it be nice to get the exhaust up above everything you are working on so you aren’t constantly choking on exhaust fumes. In conclusion, truck exhaust stacks are functional and look great, and above all, add to performance, economy, and help keep temperatures down so that your expensive truck will last longer than you need it to.
