Hmmm...I was about to order, but was under the impression they have removeable dB killers - is that not the case? Also, just curious who you ordered from - I have had some conversations with Design Corse and they seem very helpful.
So I have a 2019 dragster which is the redesign. HP Corse wasn't advertising an exhaust for my model yet when I ordered through Design Corse.
Design Corse was able to get me one for the new model. HP Corse told Design Corse that I was getting the race exhaust (no internal baffling) with removable baffles at the tips.
What I got instead was fully baffled internally and at the tips (no removable). This was a mistake on HP Corse's end, and Design Corse has been amazing communicating with them and getting it resolved.
I am waiting for the new exhaust to come in, and will send this one back.
For the non-redesigned Dragster RR's (2018 and before), HP Corse offered 3 different options from what I saw when doing my research. One of which included removable baffles.
Hope this helps!
