MHD - No Exhaust Burble?

[thegailway]

I'm in the same boat, AR ***less DPs, Stage 2+ 91oct, MHD exhaust burble set on every combo possible, only could hear the burble once vaguely. Not sure what the issue is...

Same here. I get nothing. Going to wait a few drive cycles to see if anything changes. Set to 2 seconds, aggressive, 0 RPM

The effect is much more significant without cats, do you have secondaries still? Even 1 second on medium-hard was extremely noticeable when I was fully catless, just a resonator + muffler.

I have catless VRSF downpipes but hoping to go VRSF street exhaust soon. I will say the burble is getting more noticeable the more I drive the car/run through drive cycles. Interesting....

Are you guys running burble with Cats? Youre definitely gonna ruin them if you are. Fully catless my car sounds like its blasting gunshots on medium, I had to turn it down.

I've never played with those settings and I'm catless so I can't really help you out there, sorry. Your cats may just be doing a good job. I'd tell you to turn it up more if you can but I don't want to be the reason you blow your cats out, lol

Free catless downpipes

Don't forget the secondaries. They will get blitzed if the primaries go. It'll all turn to dust.

Stock downpipes here, no ill effects yet, hoping it blows those fuckers out and saves me needing to do downpipes :lol:

No secondaries, no reso and PE mod on driver side. Its like a fucking gun shot out the back with it set to 1 second in Sport on hard. When downpipes go on it will need toned down for sure.

Just an update I believe your car needs to be warmed up to get the pops and burbles. Wasn’t aware of this. Let oil temp reach around 200.

Also I’m VRSF catless

Not warmed up fully, just not stone cold. I don't get any for maybe the first 5 mins of driving and then they get progressively louder as the exhaust and engine warm up.

Correct this was my issue. Consider this thread solved.

The exhaust needs heat in it to ignite the fuel and make the sound... Science.
