Our DCE Parts - BMW G80 G81 M3 G82 M4 Equal Length & X-Pipe Midpipe Hybrid Titanium upgrade exhausts are made from high-grade titanium. Our valved exhausts are developed for perfect drivability and comfort in mind with the valves closed, however, you can switch to a sportier exhaust note with the valves open.

What is the Equal Length & X-Pipe Midpipe Hybrid?

The S58 is already an engine that has a somewhat equal length setup from the factory with the extra bend in the exhaust. However, these sharp bends tend to make the exhaust setup more complex and still don't sound truly as an equal length exhaust setup. If you remove resonators, OPF and more, the car will still sound relatively flat. The downpipe length is the cause of this. This means that when the exhaust gasses finally mix into the exhaust, the exhaust pulses are not reaching the mixing point at the same time, causing the rough sound the S58 traditionally makes. If you just use two pipes to the back box, the car will sound loud, but also very raspy and will still have the two-3 cilinder sound characteristic. 

The Equal Length principle is to equal the length between both exhaust pipes first, before mixing them together in the center of the exhaust. This gives the exhaust a higher pitch, creating a very lovely sound profile which is loved by many. The X-Pipe section is created to allow the exhaust flow to synchronise long enough before splitting back into two pipes to the rear muffler

The DCE Parts Equal Length and X-Pipe Hybrid

The DCE Parts Equal Length and X-Pipe Midpipe Hybrid is an innovative solution that is designed to combine the best of both worlds. The Equal Length section is designed to create the higher pitch we are after to make the straight six sound more like a traditional straight six. With the resonators, we tune down the raspiness in the exhaust to make sure the exhaust note remains high pitched but also filters out the nasty raspiness in the exhaust. The X-Pipe midpipe section then tones down the exhaust pitch in lower revs, creating more bass in the exhaust sound. Then, we decided to offer this exhaust in titanium which creates a warmer sound profile. These aspects allow for an incredible sound to come out of the S58 which we have not heard before.

Our exhaust systems uses electronic or vacuum actuators for the valves, which are controlled by a separate controller, on M cars you can reuse the original valves. The high quality valves are durable and reliable and offer the best of both worlds in terms of sound and drivability.
