MMW coupled with a performance exhaust.

I currently love the sound, and am tempted by midpipes, but I can't imagine the sound it would produce afterwards lol

Probably explains your rasping.

I'm running Supersprint headers, stock mids, and a Supersprint street muffler. The headers and muffler are tuned to each other to eliminate such things.

However my exhaust is much different from Stig's.

I'm running 2nd cats, resonator and no muffler. I'm sure Stig's is a bit more civilized primarily from the fact that he's running an actual exhaust.

This sounds way better than I would have expected it to. Very E46 sounding

That might be the first time someone complimented the exhaust note of the E46 M3.

While I initially didn't like the E46 M3's note, it is definitely a unique one. It's grown on me. I wouldn't say I'm so alone either. Most of the enthusiasts I've met seem to agree

I think the s54 sounds 10x better than anything BMW has put out recently; sub the s65 and s85.

The new m3/m4 sounds terrible IMO. Either the stock exhaust or aftermarket i haven't found any of them to sounds particularly fantastic.

I'm biased towards my S54

One day My stable will include an e46 M

TheSt|G · 02-01-2015, 09:59 AM

Z4M coupe definitely sounds different than the E46 M3, likely because it has secondary cats from the factory.

Induction noise is where the S54 comes into its own.

manutdas11 · 02-26-2015, 07:50 PM

Any updates on this?

The noise is getting really loud from my DISA valves. It makes my N51 sound like an engine in a diesel truck.

I'll send them another email. I also want this done ASAP.

If this becomes a reality it could push me to get the 3 stage manifold

If you're referring to the lifters, then yes, they tick. But the DISA valves make another noise altogether for your information.

I know e60 LCI 530xi owner (N52B30), who has faulty DISA problem. Fortunately he has diagnosted and replaced broken DISA before flap flew away into engine.
Broken DISA started to make rattling sound and engine lost some power, so he checked DISA and its flap was loosen.

There is no way any of us can provide such information.

You are free to do with your car as you see fit.

Stig, did you receive an update email? Nothing on GAS website.

Nope. They apparently aren't exactly rushing this...
