Z4M Exhausts

[InductionRoar]

Is there an off the shelf exhaust for the Z4M that gives a deep tone?

After recently hearing a 14 plate Cayman and today an A45 AMG (at walking speeds) I have to say the OEM exhausts on my M are even more underwhelming than I thought.

I have scoured YouTube and every forum possible to find an exhaust that sounds exactly what I want and it appears there isn't one. All the videos I have heard make the S54 sound like a small revvy engine and too raspy and metallic. I want a deep growl/burble at low revs that rises in pitch with revs without being excessively loud - pretty much the same note as the induction but I am being too tight to spend the £3k on an evolve airbox

It seems the OEM X-pipe/resonator is a must to keep the rasp down and aftermarket X-pipes gain nothing performance wise.

The closest I have come up with is the appearance of the Rogue Diablos and the sound of the Supersprint races however, these still have a tendency to come across as ricey through the laptop - however, it may well be different in reality???.

I have Stromung Backboxes. Look superb and sound amazing. They really sound much better in person than on video. They have a lovely rumble on startup. I was looking for the exact same sound as you and the Stromung back boxes fit the bill perfectly for me. They aren't stupidly loud, very similar to OEM sound but deeper and louder. No added rasp. I'm delighted with them and they were reasonably cheap at just under £700. I imported them from the US myself direct from Stromung.

Have you tried gutting your OEM silencers?

I did mine and they sound pretty good.


Here a link to the process:

I put a Supersprint Lightweight bacbox and centre section onto my E46 M3 and it has really deepened the tone. I'm not a fan of the standard raspy note either.

every time i see haward and scott exhausts, i see great reviews,... but their welding leaves ALOT to be desired, needs to be much better for what they charge IMO, very messy work which lets down a what seems to be a decent product.

I have H&S on my E60 M5 and the bits you can see are fine. I'm no welding aficionado so its not that important to me. Sound awesome tho.

Hayward and Scott do sound good on YouTube. May look into these - shame the cars are so few and far between as I am unlikely to hear these exhausts without buying.
