Designed but not made. We have been posting some teaser clips on our IG.

Our test car has our resonated midpipe, axle back and stock Downpipes.

Does this mount up to an ER midpipe I would assume but want to make sure?
It's on pre order, when is it available?

I'm not 100% sure where the er connects. See if it's in the same area as our midpipe.

I cut it where the dimple is on each side of the exhaust piping.

Any sounds clips?

Also would love a sound clip, does this box have higher flow to negate the rasp from forced underflow/smaller boxes?

I’ll post up a few more sound clips later tonight.

Mad Single Midpipe
Mad Axleback
Stock Downpipes

Very happy with the deeper tone from the S58. Even the wife gave the nod on the change.

[M3_X4M]

The unit looks very promising and the price point is great (wouldn't have expected otherwise). Interested to hear what it sounds like with valves 100% open...

Thank you! I believe he's going with our downpipes next not sure if he will be adding valve controller or not.

I’m truly considering it. I’m currently running the ER mid pipe and Dahler controller.

I saw on the website that the carbon tips aren’t an extra million dollars and cost isn’t changed.. is this true?? Or is this a preorder thing only?

This is true and not a pre-order thing. Just keep in mind things do change from time to time depending on our total cost so I can't guarantee it will be like that 6 months from now but right now it's a free upgrade.

[M3_X4M]

Getting ready to add the Downpipes to the singlemid and Axleback. Looking forward to seeing how this compares. Will update with more clips once it’s on.
