Engine SoundModificationyoutube

FINALLY!!! The Exhaust is complete! In today's episode, we certainly pick up on this build after quite a while of dormancy while I finish up the E30 N54 Wagon, but here we look to keep that momentum going, starting with some exhaust work. 304 Stainless Polished Steel that is!! We start at the Stock S85 V10 exhaust manifolds, keeping those cats (for now, until I change my mind. Then we go to dual 2.5" output, with V-band clamps Then each leg going to individual 2.5" flex pipes From the flex pipes, it meets at an X pipe Splits back off and goes to individual resonators To another pair of V-bands to remove a the rear section Then goes to Doug's Exhaust Cutouts (link below!) Cutouts splits off to the center-most tailpipes on each side Mufflers are E38 740i, nice and quiet, and route to the outer-most tailpipes on each side of the exhaust. Doug's DEC250ak are found here! https://www.amazon.com/Dougs-Headers-DEC250AK-Electric-Exhaust/dp/B0050SF2T6 Thanks for being fans and sticking by me with this swap, While it's slow going, it's been a blast and I love working on this E31!!

About BMW 8 Series (E31)

The BMW E31 is the first generation of the BMW 8 Series. It is a grand tourer built by BMW from 1990 to 1999 as a 2-door coupé, powered by either a V8 or V12 engine. Whilst it did supplant the original E24 based 6 Series in 1990, it was not a direct successor, but a new model class with a substantially higher price and performance than the 6 Series.
