Torn between Akrapovic and Vanguard

[niqui]

how much louder would the vanguard get with the gintani xpipe? any ideas

[duk]

it would get a decent amount louder i would think

any x-pipe solution should give any axle back exhaust a much deeper and meaner tone

Also, does the rear section actually provide performance gains? Is there a dyno to prove it?

^^^?

thks
i personally dont care if the tone gets meaner, id like that.
but i dont want the car to get louder for city driving down low...like 25% more, or even more...
been toying with adding fabspeed hfcs and xpipe to my vanguard...avoid cel and get some juice, but dont want to be stupid loud.

I had the AA system on my car originally. It was very nice, but way too loud down low.

The Akra full system is on now and I couldn't be happier. More than loud enough - personally any louder and my ears would get irritated.

Full Akra is much louder than stock. My wife was out of the country when I installed mine and she definitely noticed the difference. Two forum members have heard mine at the track and since ordered this system.

I am very skeptical, as you should be, of any dyno that shows +15 hp from a cat back exhaust system (in an M3). There just is not that much room left compared to a very good stock system. Some repetition back and forth with and without the exhaust mod would very likely show different or at least as much measurement variation to convince you that the 15hp is not real. Results from a different dyno will show different results and different gains.
