Akrapovic Evo compared to OEM exhaust mod

[MWE92M3]

Can anyone tell me how the Akrapovic Evo system compares to the OEM exhaust mode (EAS) in sound?

I have the exhaust mod now but I'm considering getting the Akra Evo to replace it.

Much better, especially with ESS tune.

i think evo will be quieter

Agreed,the slip on will be quieter,but i think the evolution will be louder
Also this depends of what kind of Oem. exhaust mod.

I went from the OEM mod to the Akra Evo 2 months ago. I loved the sound of the OEM mod, but wanted something aftermarket. At startup (with cold start removed) the Akra is quieter than the OEM mod. When it comes to cruising & WOT, they sound the same in volume with the exception of the Akra being bassier. The sound that the Akra produces just sounds different, not necessarily better, than the OEM mod. IMO, they both sound awesome, especially at WOT.

Sorry to confuse you .

he said EAS, so thats pretty much a muffler delete

Evo is on the quiet side for an aftermarket exhaust. In terms of pure sound, while subjective, the OEM exhaust mod is absolutely incredible. Problem is, if you are looking for that extra power by getting rid of the primary cats, then it doesn't sound that great.

Conclusion: OEM mod sounds awesome, but only if you leave it alone. Go aftermarket if you want to delete cats

I have to disagree...I had the akra evo and was not impressed at all. The sound lacked character to say the least.

I now have the dinan x pipe and akra axel back and imo it sounds dramatically better. Cleaner and more substance to the note than the Evo did.

Agreed, not to mention the Akra weight savings and the fact that the OEM is fugly.

All the Akra Evos I've heard are pretty quiet...deep toned, but definitely pretty quiet in terms of what you can get out there now from a full exhaust. I ended up get the Akra rear with a different X-pipe (stainless steel, weight savings mean less to me than money saved and sound output) to get the sound I want for a price that's reasonable.

When i read all this,i need to say what i said many times before on this forum....
Sound is..... very personal !

How does the Dinan mid-pipe/Akra slip-on compare to the Akra Evo in terms of bass at low RPM? Does it reduce the bass at all?

To me, the Akra Evo is bassy at low RPM and then gets drowned out by the engine at higher RPM. I'd like a touch less bass/sound at low RPM and a bit more volume (higher pitched) at higher RPM.

i recently got rid of my megan+testpipes...first step was to go down to another buddy's place to swap the megan for the oem mod....next step was to go up to the valley and swap out xpipes....holy shit that drive with oem mod + testpipes WOW. shit sounded like a c63 on steroids....don't know why people say it sounds like crap without experiencing it first hand....i had the rear seats folded down to as I was lugging around the megan. then i swapped xpipe with TP for stock xpipe and that gracious noise just disappeared....to me the oem mod is too quiet for me now once having testpipes and an exhaust system.

Completely agree on this one. I like the bassy sound of the akra down low but it really does get drowned out by the engine/intake noise at WOT. When I first got the exhaust I was truely expecting something more aggressive and slightly louder with more of a growl and found it somewhat underwhelming.

It may get drowned out in the cabin with the windows up (a good thing IMO) but anyone outside sure hears you coming.

It's still bassy at lower rpms (<2K) but after that its pretty quiet when cruising for a catless exhaust. Once youre on it the mix of exhaust and intake it pretty much perfect and you never lose the exhaust sound to the intake. I def get a lot of heads turning on acceleration and downshifts.

One thing I will say though, although I hate raspy cars, I dont mind a slight bit. The akra with the dinan is super clean sounding. Not a hint of rasp at all. Its deep and has a somewhat exotic note higher in the rev range. IMO it sounds much better than the Evo system I had. At the same time there are times where I wish it was louder and had a slight bit more rawness to the downshifts (rasp I guess). I have a mastermind race I will be switching the dinan out for if I dont switch to MPE and test pipes...so we'll see how that goes.

I went from an Eisenmann black series race axel back only to Evo and had the same feeling. It was very quiet and the tone of the exhaust itself left a lot to be desired. Def not something you'd think for a 6K system. The things that makes me hesitant to switch above all is the fact that the Akra with an aggressive x pipe sounds great, is very well made, the tips are phenomenal (especially mine) and its appearance from the rear is great that you dont see it for the most part. At the same time, I really want something enjoyable to hear above all. Exhaust cans can always be painted black and made unnoticeable.

Wolf - I've considered the Dinan x-pipe - any fitment issues with Akra rear section?

No issues so long as you have tthe adapters.

Im likely switching to my mastermind race though for a slighty more aggressive note. Or switching to test pipes and MPE

[tareemaa]

I'm running test pipes and the OEM ACM mod, I think it sounds insane, between eisenmann sport and race, I get compliments all the time because my car looks completely stock but puts amg cars to shame. the akra seems like an amazing exhaust but I don't know if I can justify the cost for the benefit, especially if you are looking for sound.

[MTrezzz]

I am trying out Evo x-pipe with RKP adapters with MPE in March. Lets see how this goes!
ti & inconel!

I had that setup for a month and it was fun for the first 2 weeks, then it just got old. Sure you get a ton of sound, but it's just rasp. It's not that Germanic V8 sound that I'm looking for.

And between 3-4k RPM, where the rasp was at its highest, it was so damn high pitched that it rattled some brackets under my headliner, super annoying.

Sure, everyone at car meets loved it because it sounded either great idling or WOT. But my car lives between 2-5k, and the sound is just not for me.

my car lives at 6-9k where the raspiness gets even better! i like a raspy note much more than an old fart can note. thats just my opinion....e36/46 rasp...ferrari...rasp....yeah i like rasp.

all these other exhausts sound like my integra with apexi dunk exhaust.

(they do sound better of course than the integra but the characteristics are very similar is what im getting at )
