What about AFE?
AWE definitely does not drone, it's nowhere near loud enough. Same with every other catback for this car. The only thing that is pretty loud are cold starts. It's my favorite exhaust for this car. Valve-less but is still quiet when you want and loud when you get on it. Definitely do not cancel it out.

Resonator Delete you will hate -- its like having the valve all the time in all modes.

The MPPSK is the best of both worlds.. bonus is +2 PSI of boost (20 - 30 HP) Comfort is stock quiet (little noisier when you gun it)... but in Sportsounds like a monster...

The JB4 has nothing to do with sound. Boost has nothing to do with exhaust noise.

The stand alone MPE is on the quiet side but it is still much louder and deeper than stock

This is a tough decision. Remus cat back is the way im thinking now just need to see how much the sound is increased cant seem to find a comparison video. Its hard to tell how much it is increased.

Can anyone tell me percentage wise how much louder is the remus catback on a completely stock car, over the stock exhaust? My estimate Example: ecopro/comfort mode 5% louder than stock. Sport/Sport+ 33% louder than stock

I may be wrong but isnt ASD the only sound difference from Comfort to Sport? The car doesnt just get louder, other than the overrun/burbles. Those are basically non existent on a stock exhaust system anyways?

In fact I swear my car is louder in Comfort mode around town due to lower throttle/boost sensitivity in lower RPMs. The extra surge of boost down low in Sport muffles the exhaust tone.

Well if you consider the valve opening for passage through the other pipe rather than being forced through the muffler. Its louder in sport mode when valve is opened i belive....

Technically yes, although the difference is minuscule if any.

Thats a very good point - stock car doesnt have the burbles MPPSK will have. The tune has a huge affect - in fact I can change some setting on my JB4 to get more or less..

Between sport and comfort on a stock car barely any difference honestly.
