I am thinking about gettin the Dinan Free Flow Exhuast for my 2010 535i. I was wondering if anyone has done this to a car like mine and how happy they where with the sound? I am looking for a deeper tone for start up and acceleration but I want it to be subdude while cruising on the freeway. What are your thoughts?
None of them are very loud. They do add a deep rumble, but nothing like that banshee wail of an M5. It's because of all the noise suppresion that happens upstream towards the engine. You have a set of downpipes stuffed with catalytic converters and a semi S-loop, then the mid pipe with another cat, then a set of mufflers at the end. So the noise that is originally generated from combustion in the engine goes through a torturous signal suppression path before it reaches the opening off the Y pipe in the rear and delivers the sound off the tips.
For me, part of the appeal of owning a luxury performance sedan is to have tons of power, while driving a quiet car. The engine note is audible, but heavily muted. I love that stealth aspect of the car. Would never mess with that. Besides it is fatigueing and boy racerish to drive around in a loud car. Who would ride with you? I would rather blow by a loud Mustang 5.0 and make him wonder WTF just happened. You know, that whoosh going by. That's just me. :dunno:
Basically what I do not want is a popcorn exhaust. I just want a deep sound during startup and acceleration. After that I want it to be mute. I think I am going to move forward with getting the Dinan Free Flow exhaust. From all the people I have spoken to they say that is my best bet.
+1
I agree. However I have always loved how a Remus exhaust sounds on a bimmer and that damn mod bug bit me last week. The good thing is at cruising speed it is as loud as the stock exhaust. But even when I first take off the exhaust is only a little bit louder then stock.
I agree the Remus on the BMW's sound and look great. I had a Remus muffler on my 530xi and I loved it.
Do they make a complete system for the 535i? I would def want a throaty deep sound...
Hate to sound stupid by what so you mean cut the FS? What part I that

It's cool. FS is the front silencer, it a metal pack looking thing on your exhaust before your rear axle. It helps reduce exhaust noise.
