Akrapovic Evolution Review/Video

Just a quick video I threw together of my Akrapovic. Both inside and outside, some boring driving to show how liveable it is and a bit of throttle at times too.

I'd like to take a better video with more wide open throttle at some point, but this will do for now.

So far, I've had:

http://www.m3post.com/forums/showthread.php?t=407006
- Magnaflow - Loud and really bad drone. Great looking exhaust, though!

http://www.m3post.com/forums/showthread.php?t=410150
- UUC Corsa - my favorite tone, but heavy and UGLY. Worst looking exhaust on the market, with cans that hang down and teeny little tips. Decent amount of futzing required to make it hang right, but not terrible.

http://www.m3post.com/forums/showthread.php?t=444420
- Autobahn Exotics - very nice quality, hung perfectly, but was a TOUCH droney for me and aggressive sounding. Probably the deepest and bassiest exhaust.

- Vanguard - I liked this a lot, easy to install and ultra lightweight... almost too lightweight. It feels a little flimsy to me compared to the Akrapovic. Really quiet, almost stock like from inside the car.
- Vanguard w/ Fabspeed X-pipe and stock primary cats - weirdly, this got almost too loud, about the same volume as the AE exhaust, with a pronounced drone right at 2500 rpm, gone by 2250 or 2750 rpm. Had to drive around it, but was nice other than that.
- Akrapovic slip on w/ Fabspeed X pipe and stock primary cats - This setup was ok, but almost too quiet. (the Akrapovic slip on with stock secondaries and primaries would definitely be too quiet for me!) Nice sounding, but not aggressive enough.

Now for the full evolution system:

This is by far the nicest exhaust I've ever seen. The lightness is what really is astounding at first, but then you look at the welds and realize how beautiful they are without any kind of cross contamination or coloration... it's almost too beautiful to bolt onto the car. It has really nice triangulation and reinforcement, and amazing fit and finish. I didn't have to futz with anything except the tips when I was installing it, and even then, just barely. Thanks, Eric at PYSpeed and Darwin at SonicMS!

This exhaust is clearly build to last and to take some abuse. It's beautiful but definitely function over form, which I love the look of. I can see some of the justification for it being more expensive than most of the rest of the exhausts... it is definitely built heavier than japanese titanium exhausts (like the Vanguard or some of the S2000 parts). I like that, it feels much more substantial and less fragile. Still saves over 50 lbs from stock!

I was kind of stupid and bought the slip on for use with my Fabspeed X pipe and stock primary cats. Unfortunately, this proved to be too quiet for my taste, but is a nice daily driving combo. I ended up just selling the Fabspeed and picking up the Akrapovic midsection.

Fitting the exhaust is really easy, and it fits perfectly. You've got to remove the underpanels to do a really good job installing it, but it is pretty easy and straightforward. Definitely easier on a lift, though, I would not recommend doing it on ramps like I did.

Make sure to use the anti corrosion grease on this, especially where you have steel to titanium connections, as galvanic corrosion is a pain in the arse. (and yes, Akrapovic includes this stuff.) Akrapovic recommends cleaning it with WD40. If you do this BE CAREFUL since that stuff is extremely flammable. But, definitely clean it off, as fingerprints will burn into the exhaust if you don't.

You will have to find some solution to keep the SES light off. Best thing is software. Dinan Stage 2 software works fine, I suspect the ESS makes a bit more power, but the Dinan works fine. Probably 10whp or so difference.

It is definitely louder at stock than idle, which was kind of strange. Cold start is loud and bassy, your neighbors might not approve if you start work early. However, it's always quiet and refined inside, but makes a nice tone when you step on it.

This is a small thing, but I think the Akrapovic is the most aesthetically pleasing exhaust out there. It really tucks up underneath the rear bumper nicely (and looks way better than stock. ) That said, honestly, my favorite exhaust note was the Corsa. It has a nice exotic high pitched tone, best thing this side of a Kreisseig. But, like I said, I didn't like the look.

The Akrapovic sounds really nice. It shuts up the best but then opens up nicely when you give it some gas. I love the way it sounds... just not quite as harmonic as the Corsa. But, the Akrapovic is really nice.

If you think the stock exhaust drones at 2000 rpm (which is does just a touch) the Akrapovic does just a hair more. It's definitely liveable and seems to be chilling out a bit now that I've got a few hundred miles on it. No drone at all on the freeway.

The downsides... the front pipes are so light that I got some resonance in them at 3000-4000 rpm. Not bad but a touch annoying. The tips took a little bit of futzing but were not bad at all. Anyone else seen the resonance? Got a solution?

Here's some video:


Fast forward to 3:10 for the good stuff.

Maybe the best exhaust review I've seen on the boards. You do a great job giving a real world perspective of the car/exhaust sound experience. Very nice work, thanks for the effort.

Awesome job kitw! I should have mine installed in a few weeks. Can't wait.

What's the butt dyno telling you? You feel a difference in terms of performance over the other exhausts? TQ dip noticeable? Keep us posted if it gets louder after a few hundred more miles.

I definitely noticed the power on this one, unlike anything else I've done to the car. Honestly, the torque dip is there if I really look for it, but the car is geared short enough that it's not an issue. Still feels way faster than my wife's slushbox 335i.

I'm thinking all of kitw's exhaust purchases have been funded by akrapovic so that he can have credibility thanks to the experience of owning half of the exhausts on the market. The circle is finally complete now that he has the akra and proclaims it to be the best of all. Well played, Akrapovic, well played.

Sounds better in your video than it did to me in person. Doesn't seem like there's a better all-around setup if you don't mind doing what it takes to get rid of the CEL, just another good excuse to mod some more...

Depends on the Dinan reseller but probably yes.

Hahah.

When I bought the m3, I told a friend of mine, "this car doesn't need an exhaust!". 6 setups later and I have one of the most expensive setups available. Wallet FAIL. Oh well.
