Talking IPE or Akrapovič Evo

Hello, can someone tell me which exhaust system is better between IPE and AK EVO? For example the performance gain from them and the sound they create. How about the resonance?


Thanks very much!!

Akra is low and bassy where is IPE is high pitch and exotic. As for performance I'd say very similar with a slight advantage toward IPE due to the fact the akra evo has cats (extremely high flow) and the IPE doesn't so it should make a bit more power. More of an apples to apples comparison would be the Akra Gt4 system (Fully catless) vs IPE.

Akra Evo will give significant weight reduction as well, it has HFC, X and H sections in the Evo system. You may want to go with a GT4 x-pipe.

IPE F1 is catless. There is a huge merge section on the X Pipe.

Soundwise, Akra is shit, IPE is fine. Kreissieg is the best !

i wouldn't say the Akra sound is shit.....it's alot less obnoxious sounding than some systems. IPE is is LOUD. youtube some vid clips and see how you like both.

I myself have the full Akra Evo system and it doesn't drone. It's mellow and when you get on it, it sounds great.

Had both systems and the Akra is better IMO. Significant weight reduction and beautifully crafted.

Depends what you want volume wise. The Akra, even Evo, is not loud at all.

IPE on quiet must be similar to the Akra. IPE on loud must be really loud!

i definitely agree with you!! i have a IPE f1 system and its just hard to believe that an m3 can produce such a sound, if i had the $$ i would of went for a Kreissieg system , but in my opinion i think when it comes to performance akra and when it comes to sound IPE!

The F1 I know is catless and thus smells and also causes a CEL.

Is the evolution catless and does it throw a CEL?

the Akra will throw an CEL. I got that problem taken cared of through my BPM tune or you can go with the akra delete-r. IMO the IPE is loud as hell but than again I must be getting old LOL and not to mention i don't want cops on my ass lol

Yes it does, as it removes the censors near the primary cats.

There is a specific tune for the evo mid-pipe. Most of the tuners have it. (BPM, Evolve etc)

No, it's not significant, not something that you'll notice. You will notice an overall power increase.

The good news is these two exhausts are very different in sound. Comes down to personal preference -- see vids. Power gains will be equal, Akra weighs less.





I'm always a bit amused by forum guys claiming the Akra sounds horrible... I can understand if it's not your favorite, but it seems we've got a bit of a love it/hate it scenario going on with this exhaust. It's either the greatest thing since sliced bread, or it's a ripoff and sounds terrible.

Put it this way, in person I've been approached by everyone from other M3 owners, to Miata, to supercar, to musclecar guys with compliments on the Akra.

Another forum myth -- the Akra isn't loud. Perhaps not as compared to catless with Eisenmann race, but as compared to stock and most catbacks it's plenty loud.
