Hey guys,

Can you give input about which exhaust in your opinion is better? I am slightly indecisive on what I might install during summer and I need to choose now so I clear it up with my dad.

Thanks

Akrapovich sound ... I would go with akropovich if I had to choose between those too .. Ps. ( I got meisterschaft Super GT for sale if you interested in that too steal of a deal )

[M-terkait]

i would go with CG

[Krelle]

I got the Akra. Love the sound, about 3 dB above the oem in comfort, just enough not to get tired from listening to it.
In sport you really wake it up.
It has no drone in any of the modes !

The Akrapovic is definitely the leader for the best sound

[CG Precision]

I think CG has the best sounding and engineered exhaust! Haha

We have quite a few guys on here running our system. Do a quick search and read the reviews for yourself. I think you will get all the info you need!

We love the competition and are flattered that our small company is being compared to such an great, large company, such as the one mentioned in this post. So thank you very much!

And to the guys at Vivid.....we are only a a few miles down the road from you guys! We should meet up. You maaayyyyyy just change your mind.

Merry Christmas and Happy Holidays everyone!

[Agamemnon]

Running an Akra myself and quite like it. That said, it is really nice to see CG Precision on this forum and producing a product that compares favourably. Good on you!

I think both are overpriced. $2k for a cat-back is just stupid. But, I guess that goes with the standard BS that you overpay for anything related to German cars.

Hi guys,

New here, recently bought a 2012 335i. First mod is an Akrapovic, received it yesterday.
Here some quick pics:





Going to install it this saturday, will make some pics (and movies).

i haven't heard Akra in person but know some people dislikes it as its not loud relative to him/us teenagers so i think it might be not the best if you like to go racing/autocross.

maybe it may sound good with downpipe

[Agamemnon]

Don't agree about loudness. When in sport mode and really wailing on it, it sounds the business with fabulous pops on upshifts. It is quiet on the freeway in comfort mode - isn't that the best of both worlds? Who wants drone on the freeway for hours on end?

i have IPE and it doesn't drone even in open mode which is literally straight piped it doesn't drone unless you pass 50-60% throttle on high gears with low rpm.

and in closed mode it doesn't drone ever.

its like having comfort mode and Track mode
but the problem with it is you can't have something in between its either stock sound (comfort) or track race loudness.

Hi guys,

In case you are not familiar with our setup, hopefully this will answer some questions.

- Our system was designed as the only true 3.5" system from the cat connection back, with no kinks or crushing of the piping. It comes with a CNC V band adapter flange to mate to the factory DP, but when used with our DP it fully eliminates the restriction of the factory size piping and becomes a true 4" to 3.5" exhaust system.

- We recently released our catless DP and will be releasing a superior flowing catted DP in the months to come, after we have finished our testing.

- Our system was designed with 3D exhaust flow simulation (see below) in both open and closed modes to create a very free flowing system with a sporty sound worthy of the racetrack when open but subtle and stealth while closed.

- Because we tune the muffler to have 15% of the exhaust gas, of certain sound frequencies, muffled when the exhaust valve is open, there is virtually no drone even when the valve is open (See flow analysis below)

- Like the Akrapovic, our system can use the factory Comfort, Sport / S+ settings.

- We have also engineered a controller for the electronic valve (the VSC-1) so you can open or close the valve any time you want.

Exhaust sound is subjective and everyone has their own favorite. If you are looking for a very racy sound, but not obnoxiously loud, with the highest flow possible, and ability to control the exhaust valve, we think you would really enjoy what our system offers. Good luck with your decision and your build! Here is the flow analysis:

That was highly educational, Thank you!

[JMcQueen]

On sound alone I think the Capristo sounds the best.

[Krelle]

Capristo is nice and has many features but only fit the 428i and 435i.
I checked this before buying Akrapovic.

I was split between Meisterschaft GTC-EV and Akrapovic. I researched multiple vendors, there seems to be missing pieces from the "base price" on both units. For the Meisterschaft - you need the AR piece to make a complete "cat-back" system. For the Akra, you would need the "link pipe". Adding those, both systems went over $3000. I like the deep loud note and 102mm dual tips of the Meisterschaft. I like the carbon fiber tips of the Akra but the sound is a bit raspy for me. If you like to control the valve, Meisterschaft gives you that option, Akra is ECU controlled.

Due to the annoyance of the previous 2 units' pricing scheme; I decided on the CG unit after viewing some members videos. It comes with 2 remotes to control the valve. The sound note is perfect! low but not raspy. Not that crazy loud; drones a bit at 1500-3000rpm, but that is ok by me - I need to know I have an aftermarket exhaust system. Afterall, who buys exhaust for HP? - if you buy for looks, then just buy the Cyba tips. CG's dual tips is just a little bigger (maybe 3-4mm?) than my old Sport exhaust tips. The manual is detailed enough for you to install yourself. This adds a whole new level of driving exitement - I dig it!

Great notes. Can I ask if the CG exhaust has a drone when the valve is closed or only when it is open?

very helpful thanks!!!

For my point of view your exhaust is better of Akra

When it's opened, very noticeable with windows down. Can still hear it with windows up.

When it's closed, can still hear it but not as LOUD with windows down. The road noise actually drowns it out. With windows up, can barely hear it.

Funny thing about this exhaust (not sure about others..), "comfort" mode is actually louder on accelation than "Sport/Sport+". Not sure why, so I found myself driving mostly in "comfort" mode.

For your information, the drone and acceleration note is kinda sexy. Not fart-can-like on the aftermarket civics,darts,acuras, evo's, etc; and definitely not v8-pretentious.

Made a video of the Akrapovic in action today:
