Unicorn X-Pipe - E39 M5

2.5" X-pipe constructed in T304 Stainless steel, mandrel bent, TIG welded & back purged. The X-pipe replaces the factory resonator and uses factory mounting points to secure X-pipe. Features a splayed X-pipe for optimal smoothness of exhaust cross-flow by balancing the exhaust pulses from each bank. Integrated v-band clamp assembly at the rear of X-pipe to provide ease in removal of exhaust mid-section without necessity of removing mufflers. 2.5" outlet connects to any aftermarket or stock mufflers. The resonated version incorporates two 18" long resonators aft of the X section. The addition of the two resonators add a deeper and cleaner amplification of the mufflers' intended sound.
