DO NOT install the ZCP Sports Exhaust on your standard M3/M4

You might very well be correct - I was just throwing out ideas on why it would sound different.

My understanding is that coding is primarily responsible for the ZCP burbles and GTS-like start up roar. Not hard to extrapolate that into being part of the reason why a ZCP sports exhaust sounds "different" on a civic M3/4.

on a side note, why do y'all call the standard M4 a Civic M3/M4?

I think it's an inside joke, I am not really sure - I just have seen the distinction referenced that way.

ouch, I wish he waited for a while for the exhaust to break in before replacing it back with his stock exhaust. Oh well. I did what I had to do...

This video does not apply to the OP topic, since the cars exhaust is not "stock" with the addition of the AA MID Pipe in both videos, which would make either setup sound better on its own with that mod. Definitely sounds good in with that setup in the video.

Side note... why in the world does everyone shoot videos with the valves closed; who really cares how quiet the exhaust sounds?! I've yet to hear a system running valves closed that sounds good, let alone most ppl on here seem to either pull the plugs, or use a valve controller keeping them open 100% of the time.

+1

Every video I've seen starts with the valves closed, who cares! Give meh teh max aural pleasure! that's all I need to hear!

Even my MPE Sounds like a Toyota Camry with the valves closed

This.

It was a joke about the base M3/4 being worse than a Civic in build quality or performance. Something along those lines.

It dates back from the E9X days, when the CP was released and became the "thing to have", where plebian non-CP M3 were no better than Honda Civics. Pretty much the same debate happened with the F8X, hence why the inside tag stuck.

I think so too. Coding the valve logic in the muffler.

I had the zcp exhaust installed on my non-zcp 2018 M3 two months ago, and I can second the fact that it does indeed sound deeper and not louder. In fact, I think my car may have even gotten quieter. Nevertheless, I feel like it fixes the sound issues that the stock exhaust had such as that dreaded rasp sound at high rpms, so I’m glad I changed it. I also like that the tips are a nice black chrome to match my wheels. I did get the exhaust for free, however, and if I had to pay for it I probably wouldn’t drop the money.

The ZCP with an AA midpipe sounds as good as the MPE imo.

If I had a non comp car, I would definitely upgrade the exhaust to a ZCP and if out of warranty, tune with an AA midpipe. Much cheaper option than the MPE.

I've got a brand new ZCP exhaust sitting in my garage and can't believe I haven't moved it yet.

And to the OP - louder doesn't necessarily mean better.

[Deteria]

The easiest way to get a non ZCP to sound good is to get a tune and get burbles turned on. Spending the money and effort to swap to a ZCP muffler yields minimal results.

All you'd really be paying for is some perforations and black tips.

I think its the mid pipe and software doing most of the work

I was sceptical until I heard this in person - have to see the sound is on par with MPE.

Very smart mod at a fraction of the price.

i think the aa midpipe is to attribute for that. Theres no way any stock exhaust sounds like MPE. The tone is very different. Albeit the MPE is raspy so it kind similar to stock.

Exhaust Purchase Steps.

1. Valve controller not good enough...
2. AA midpipe not good enough...
3. full catback not good enough...
4. tune if your not zcp not good enough...
5. downpipes

or just buy the whole catback from day 1 like many eager customers on this fourm

Understand your reasoning. But 8.5K for a cracking exhaust is criminal.

I think in retrospect if I was tuning, AA midpipe and ZCP would have been a better option.

The MPE is just way over priced for a crack prone exhaust.

I have the burger tuning obd module and just have the flaps permanently open.

yeah honestly with your combo your probably 90% there tbh. the valve controller and tune are huge. and the aa midpipe is the prime reason for volume increase.... I run remus +aa midpipe. you can def steal a remus slighty used under 2K and makes the tone beast
