Waking up this G82 M4 CSL with our PSI G8X Midpipe and DAHLER valve controllers. A complete necessity when looking to get the most out of this platform.

There are many downpipe/midpipe/exhaust combinations but I have to say that after watching the video above, I find that to best sounding system I've ever heard on this platform.

Sounds great! I went with DPs to avoid cutting the exhaust but need to get some decent videoclips together to compare. It sounds like your mid-pipe may provide a bit more burble volume than straight-pipe DPs alone. Either way, the Ti muffler definitely makes for a distinctly different note than the steel version.

I love the PSI Midpipe on my M4. This is how the M4 should sound.

Tbh sounds just like my m4c with psi midpipe. Once the valves are open doesnt matter what suitcase you got, cause its going straight out anyway.

Video doesn’t demonstrate wot which is where the aound profile matters

Doesn’t sound any diff then the m3 and m4 just because it is a csl doesn’t change the note same engine same displacement.

The titanium coffin does indeed have a different tone perhaps too subtle for the disinterested to care about. But to say same engine and displacement means same audio is just dumb.

They could have saved us all alot of time by just cutting to the last few minutes. We all know about the CSL. Even the sound and vids do not support what they are trying to promote here.

Video was not made for Bimmerpost. It is made for our wider Youtube audience who do not know about the CSL.....

After installing 50+ PSI mid pipes in-house on G8x manuals and comps, the CSL with the Ti muffler sounds very different and louder, which may not be evident on the clips.

It’s typical YouTube.
10 minutes for 30 seconds of value. That’s why I no longer click on YouTube links from Bimmerpost.
