was recommended to me on you tube yesterday

Sounds pretty good to me. Anyone here has one?

I just don't like how the tips stick out, I wonder if could be installed better but this being the valvetronic video seems that they would try to get a more oem look on the tips because this does NOT look good.

I watched the V2 video on the M3 and it had me contemplating swapping out my Akra system.

Let us know if you end up doing it

Glad you like the sound! Where does it look bad?

Vendor posted a group buy, not sure if it's worth the change from my AA EL Res + Remus Race setup, but definitely would be worth it if I still had my stock setup.

I do want some more character in the lower RPM's- Thoughts on adding a HFC (AA) vs trying the Valvetronic setup?

The tips seem to stick out too far, that's my only complaint personally.

Glad you like the sound! Tips were out just due to the system expanding during the heat cycles. They can be brought in more. Here is a video with free flow downpipes:

Bad is simply my opinion as I don't like how far they stick out, I'm sure it can be corrected.

As far as the sound, one of the best I've heard online if not the best, once again....my opinion.

Here's my preferred look...if only it sounded as good...lol

We appreciate you articulating this! Those Dinan tips to look reasonably spectacular. We have our own single wall tip options that can be fitted to this system adding a more OEM+ look. Admittedly the tips do stick out a little far in the video.

[MooMooM2]

thats why I commented, they are sticking way out, it doesn't look good to me. Flush with the bumper is imo how it should be. I know in some other systems there is some adjustability.

Also the dinnan exhaust looks good in that picture but it hangs way too low in others so not really perfect. I have seen some remus and akrap that look pretty perfect. Be awesome if yall adjust it to be flush, trust me a lot of people would be into that since it does sound fantastic and valvetronic quality is tops.

[drp087]

+1 on making it flush, I thought it was just how it was installed in the videos, but now that I look again it doesnt look to have much room to shorten ~2".
Odd that the F80 setup sits flush.

Valvetronic used my car in the video. When I get back home later this week I can check and see if the tips can be ajusted to fit more under the bumper / diffuser. I am also happy to answer any other questions. So far I am extremely happy with the quality of this exhaust and the aggressive sound

[drp087]

Yea the tips might be just the deciding factor for me.
How is coldstart- any rasps?

[MooMooM2]

tips also a deciding factor for me. Not in the market this this year (have other things ahead of exhaust like suspension and bucket seats) but probably next year or so. But tips being flushed is important to me and if I am going to spend $3k has to look right.

Also no disrespect but I am surprised that Valvetronic, an exhaust company installed an exhaust with the tips that far out. Look it sounds fucking great but has to look right when you release marketing material imo. Or maybe people like their tips that far out but at least from this forum I know its not something people want.

I was able to adjust the tips in more, below are pictures of how far I could move them in.

Pics did not load for me, but followed the links that showed up when I tried quoting your post. Do the outer tips go in more at all? I would prefer the outer tip to go in more to follow the bumper. Even the inner tips look like they should go in more.
Any side shots much appreciated!

[MooMooM2]

definitely much much better but also would love to see what it would like with both tips pushed back as far as possible, I actually think the inner looks good now but outer still way too far.

I think this is about perfect

That's perfect, Valvetronic Designs or Iparkharder any pics of the tips all the way in to this extent?

[fixa]

Any interior sound clips of how this setup sounds at low rpm city driving? Does it have the typical drone of some other systems? Would like it to have more sound down low but not annoying. Thanks.

Alright so I got the exhaust to test out, installed couple days ago and here are the findings:

EXHAUST TIPS. As we all worried, they do stick out too far about 2". The driver's side pipe has about 3/4" that you can cut off for better fitment, and the passenger's side has just a bit more room, but even then the drivers side will stick out another 1 1/4".

I've contacted Valvetronic about this and their best advised solution is to cut the end and weld to my liking, but I'd prefer not to go this route just because since theres no turning back.

My other solution was to get shorter tips. The only tips I found that could match are these bimmerplug tips and think they will just be short enough to sit flush. Yes, it was frustrating having to find remedies for something that should be given, and have to pay extra for more parts or labor. My guess is that they are using the same rear muffler from the F80- just different piping for the F87, so we are left with an extra 2 inches.

INSTALL. Below is pic of AA's EL vs Valvetronic's just for reference. Other things to note is that one of the bolts that connect the midpipe to the downpipe is EXTREMELY hard to get to. Sockets will barely fit between the two pipes at the beginning of the midpipe. I had to remove of the bottom covers and go from the side/top, which was still difficult to do since theres such a tight angle. Also, there is only one valve actuator on the passenger side thats used- you need an extension cable that is supposed to come with the kit. I did not get this so I used my Remus extension for now- I've contacted them to get it separately. The driver's side is just ziptied to one of the frames. Other than that, rest was pretty simple, relatively easy exhaust fitment.

SOUND. After the disappointment with the tips being too long, I honestly wanted it to sound bad so I can just sell it off and go back to my AA/Remus. But I was wrong.

Short Version- the videos Valvetronic posted is pretty accurate. It has much more character in terms of low-RPM rumble, and high-RPM scream. It is VERY competitive to my AA/Remus setup.

Long Version- so this is comparing it to my AA EL Mid (Resonated) + Remus Race Setup.

Valves Closed/Open- Valvetronics has a MUCH bigger difference between the two modes, and as a result, Coldstart is a little quieter than the Remus. In normal driving in Efficient, it is slightly deeper down low. On the other hand, since with Valves open it does not have the resonators from my AA EL's, it has a little more rasp and I think it gets louder at higher RPM's.

Drone- to my surprise there was no drone on the highway. I only have one rattle that I can probably get out with adjusting the pipes a little.

Character. The Valvetronic is deeper down low, and at 5K RPMs+ it just gets loud. The AA/Remus had less sounds down low, but at 4K+ it just sang. I was hoping the Valvetronic kept both characters, but unfortunately it's lost a little bit of the wail close to redline.

That all being said, I am going to continue testing this out a little longer, either way I will have one exhaust setup for sale!
