Interested in cat-less DP, not interested in pops and gunshot sounds
I've been kicking around the idea of switching to a catless DP on my F32, but I'm not at all interested in any of the noisy pops and noise that I've heard in pretty much every single YouTube video that demonstrates catless DP's. Some folks have said that BootMod3 can tune out the loud bangs and gunshot noises, but I'd really like to see some videos if anyone knows of any.
I'm all for the performance gain, but I don't want my car to be any more of a cop magnet than it might already be (dark tint all around plus no front plate). Has anyone here gone catless but managed to keep the noise to a minimum? I have MPPK and M Performance Exhaust now, the butterfly valves are disconnected because that's the way it was when I bought it. I might reconnect them, but I really have no interest in the loud crackling once you let off the gas pedal. [IMG] View post on imgur.com [/IMG] |

MPPSK with catless DP won't give you gunshots alone if that's what you're after. Only a flash tune will give you that.

Yeah I wasn't differentiating between gunshots and burbles. I see what you mean now. I like the burbles on overrun but not really interested in the "gunshots" either.

Thing about Carolina is they are so concerned about the environment cars like my COBRA are exempt from the regulations & annual testing. Lots of specialty cars running around here without EGR & Cats. I just feel so guilty when I drive it.

There are high flow catted downpipes available for these cars. Might be worth looking into, the cats help to reduce the pops in my experience.

The complete lack of hard crackles and pops is more important to me however, than another 40-50 or whatever horsepower that I probably wouldn't get to use anyway, except on very rare occasions. I just wouldn't entertain the concept of going catless unless I knew for sure it wouldn't sound like every other catless BWM I've ever heard does. |

To answer the original question, get bootmod3, and modify the OTS map of your choice. You can turn the burble duration and intensity to "zero". Modifying the map is very easy and takes just seconds. These cars have burbles from factory, just fyi.
