APR teases with a clip of their exhaust

Was so worth waiting for this to come out..

I am just hoping they have not pulled a stasis and this thing actually sounds the same in person, and not softer and quieter...

Sounds damn good to me. Would like to hear it in normal driving under part loads.

Very nice.

it reminds me sorta of the vanguard exhaust system on the 335i. However the APR one has more of a exotic note to it that makes it different but yet similar in some ways..

Sounds amazing I cant wait to pick one of these up from APR http://www.youtube.com/watch?v=KlTivlEqtbQ

that's what this car really needed from the get go, amazing..

I can't help wondering how loud it is inside, particularly cruising at highway speeds. Also, I wonder what they did about the "drone" issue. Time will tell, I guess.

There was an in depth post from Keith on Audizine regarding the RSC technology they use to combat drone. It got a little messy as it became a vendor war, but search RSC in the Audizine S4 forum and it should pop up. It seems to be a very promising technology and product from APR.

I am a little worried from the teaser that the exhaust is a little too loud.

No offense intended, but that exhaust makes the BMW sound like a Honda Civic that one of the kids in my neighborhood drives.

wow - that's not bad. I didn't think i'd ever consider exhaust - I haven't liked anything I've heard so far. But this one sounds sweet.

LOOOL no offense takin I do not know anyone who has this exhaust system so yea LOL. I dunno it sorta reminded me somewhat of the exhaust, not a whole lot but when I heard the APR tease video, i was like vanguard like.. hmm interesting.. but the APR one sounds INSANELY better Ill agree to that...
