To keep this short, I have a decatted MPE exhaust with a stage 1 bm3 and burble aggressiveness flash at "5". Will this result in my muffler burning out a lot quicker? Or is it the downpipe thats just taking the hit? How does this really work

I believe burbles happen in the turbofold, not the downpipe.

All I’ve heard is “it’s okay since you run catless”

Surprise you are running catless. Definitely destroys your emissions.

So, my thoughts are the explosion for the burbles happen in the turbofold and that and the downpipe absorb most of the heat. I'm not sure of the difference between exhaust temps at the muffler between OEM MPE and MPE+Catless DP+Burble Tune, but I don't imagine them to be high enough to cause muffler damage. The muffler is stainless steel and "i think" the outer covering is titanium. 304 Stainless has a temp limit of 1700F, 409 stainless is 1250F, and titanium is around 1100F from a quick google search. 304 and 409 are the most common stainless used in exhaust, I don't know what the MPE uses. I think the best way to get your answer is to look at the EGT logs from bootmod3 to see if they're approaching those temps. I have no idea off-hand how hot M2 EGTs are. You can also get a thermometer and measure the temp of the muffler. I've also seen downpipes glow red hot on racecars without issue.

Very thankful for this answer!
