Has anyone here ever purchased the Akra Evolution Exhaust and been disappointed?

With either the sound, gains, aesthetics or CEL issues (or anything else I am forgetting)?

Obviously, opinions are subjective...but I am wondering if there are "similar" types of complaints with these exhaust systems, so I can be as fully informed as possible when making the decision what exhaust to buy. Had an Akra for my Supercharged C63 and loved it, but not planning on modding the M3 to that extent.

Thanks!

It's mostly sound and weight savings. Exhaust sound is subjective and the only complaints I see on this board are that it is too "quiet".

But pairing an Akra to the S65 that sings to 8,700 RPM (with a tune) is f'ing incredible.

I highly doubt it. Maybe if you're one of the crazies who needs a tremendously loud car, but it honestly is the best quality and perfect amount of sound (at least for me) to be a mix between comfortable, sporty, and dont F*ck with me

Very few people will be dissapointed with this brilliant exhaust.

The only two things people will point out outside of the volume:

1) The very large torque loss under 3000rpm
2) The slight ringing noise at certain rpm's

For a daily driver, Akra has the best sound, and gains. Weight savings are also impressive. If you want something more performance oriented, or louder, there are better options available, but that all depends on what you want out of the kit. It really is a phenomenal piece of craftmanship though.

One thing you can count on, is yellowing/bronzing of the tips. Hope that helps.

I still don't get how that's acceptable or why people buy this exhaust for alot of $$$ to lose the torque when this motor needs it most.

I'll stick w/ my deafening Gintani

I wasn't aware of this. Do you have a before/after dyno?

Most dyno operators dont even start until 3K RPM.

Wow that should match your exterior nicely then

Mine are now oily (like someone rubbed the inside of the tips with olive oil) and black with a hint of orange from the Torco lol! How was lunch?

Unless you track your car I dont see the appeal.

Then again I do prefer loud exhausts so maybe I am bias.

That's referring to the titanium ones correct? Or at least the yellowing isnt visible on the Carbon "Wrapped" ones?

I am also thinking about doing the "slip on" version...in case there is a more persuasive case to purchase a full cat-back exhaust at a lower pricepoint and get more power but retain a tone that is menacing enough but not obnoxious for a daily driver.

First I'd heard of this. Is it correctable with tune? For example, the ESS Akra-specific tune?

The car doesn't have any torque there anyways!

Type into google 'akra dip'

Very well known issue.

It can be tuned out in various ways. We use changes in the VANOS tuning.

Are you talking about the carbon or titanium tips? Does the carbon fade from heat/sunlight?!

The Akrapovic is one of a very few exhausts that uses resonators and higher quality secondary cats.
The power difference is minimal at higher rpm on other exhausts.
The difference is really at the lower rpm's.

yes. this is referring to the titanium tips, not the carbon tips. the discoloration on the titanium tips is not fading, but rather discoloration from the exhaust deposits. it can be cleaned to restore the color almost back to original - but it's a pain.

I have seen dyno's of the Evo, But can some post up a Chart on a pretty much stock car with the Evo? SO we can see this " Major Dip"

I have to say I rarely find myself below 3000rpms (and basically never at the track) and if I am below that then I'm certainly not expecting to have much accelerating power anyway. Its not like this car pulled from down low anyway

I just uninstalled the Akra and went with oem setup. Not many go that route and believe me akra produces a lot of low and mid range torque with a tune. ( maybe its the weight saving ) but the responsiveness my car had with the akra seemed to mellow out with the oem setup.

Yes I'm 99% sure the tune picks up the torque specific to the Akra exhaust.

I wouldn't say it's the best sounding exhaust out there, but it's very livable. No drone either. Race exhaust sound awesome, but make your ears bleed while cruising.
I'd also prefer 200cpi cats.

Workmanship is the best hands down.

Is there low end torque loss just with test pipes installed on a stock system?
