BMW X5M/X6M F85/F86 Racing Valved Exhaust system| GWAPOTech JAPAN
The exhaust system for BMW X5M/X6M F85/F86 consists of
① downpipes, ② center pipes, and ③ rear exhausts.
First, we will introduce the downpipes starting from the front side.
Here is a comparison image between the BMW X5M/X6M F85/F86 OEM downpipes and our downpipes. OEM downpipes have large catalysts due to strict emission regulations in the Eurozone, resulting in naturally lower sound volume.
We offer straight specifications without catalysts or 200-cell sports catalysts* (available at an additional cost). This not only increases sound volume but is also highly effective for weight reduction and horsepower tuning.
Next is the cat-back system, an essential part of sound tuning following the downpipes. Here, we introduce both the rear exhaust and center muffler simultaneously.
OEM center pipes feature large silencers, suppressing exhaust efficiency.
In theory, significantly increasing sound volume by making this section straight is possible, but ignoring exhaust efficiency can lead to undesirable sound quality and potential cracking.
We adopt a high-pitched specification to increase the high RPM range, employing a center pipe with an X-pipe design at the crossover section for left and right exhausts.
For the rear exhaust, we employ a variable valve system that allows switching sound volume according to usage.
To add distinction between ON and OFF modes, we use larger exhaust tips and design to match the sound level of OEM silent mode, ensuring peace of mind during night or residential area driving—a gentlemanly specification.
When the valve is open, it maximizes engine potential, producing a racing sound that enhances everyday driving experience.
We offer a variety of exhaust tip options so you can choose the best design that fits your vehicle's image.
We also offer wholesale prices, so please feel free to contact us!
