Pulled the trigger on the Akra Evo. Basically boiled down to this:
- Balance. IMHO, the engineering, materials, build quality, weight savings, and small (but nonetheless there) HP/TQ increase fits the balanced approach of the M5 brilliantly.
- Sound. Went round and round on this. While I do think that other exhausts may be louder or have a more pronounced bass-like note, the Akra was the right combo of somewhat OEM sound with a bit more treble than the other exhausts. At least to my ears. Something that really helped (after Saturday's rev-fest!) was watching videos with headphones. Huge difference vs. computer speakers (on my 27" apple display) and I found very this much closer to the real-life exhaust notes. The Akra has a clean note.
- Tips. I like the E 102mm tips; similar to factory but more proportional especially with a dropped car and spacers. Taking that up one notch is the cutback on the Akra. Just another design element that is a little different. In my case I ended up going Ti tips, as I like the fact that they don't get lost in the rear diffuser like the CF. Also, another "win" is the ability to purchase the CF tips if I get bored. Not a bad option.
- Don't want to be a copy-cat. There are literally a half dozen Alpine White M5's here in the OC. A couple with E 102 tips (race and sport), RPI, and Akra CF. Since all of these have been done - and this is something to personalize the car, the Ti tips will be just different enough to set the car apart.
I don't think that anyone can go wrong with any of the available exhausts, and that is what I think makes the decision difficult. Horses for courses. Best part is if it does not live up to expectations I can always swap it out pretty easily. Or add downpipes  |
Great choice buddy! The akra system is truly the highest build quality and the sound is unique and definitely can be heard inside the cabin while not compromising the luxury car personality that makes the M5 so wonderful. I cant wait to see your car after the swap.
I'm excited for you!
