In my opinion is welding on the 3 bolts from the cap not possible without destroying everything.

Finally I got!! Nay, my buddy did this job!! Just to clarify, my buddy (beli_mawr_pothos in Instagram great photo shooter) has an high level handling capability so for sure “not for all”.

FIRST STEP : is mandatory to kill the center pin making a sign with an angrever ( not sure of the translation...) and with a very good drill with adjustable RPM to destroy the pin.






This will allow you to get enough space to put a screwdriver on the screw head with an hammer!!



And finally the DB killer!!





I confirm what I said about the screw brand the code is on the head screw.
In the next days I will write my feeling without dB killer; after few miles with it I can say I dislike that configuration due to the high torque in the low rpm and a loss of power at high rpm.

I’m not a noise lover but with it is more like an electric bike ....

I get a laugh from google translate’s results.

Interesting. The DB reducer in the EU apparently is substantially different from the US version, which makes sense as I think about it as the sound level regulations are stricter then those in the US. It looks pretty clear that the output port is a much smaller diameter then the US version.

Here is mine, used mm for your benefit...

Order a US tube. Assuming OP has a 4 inch muffler like on Super Street system:

Just to say, the dB reducer I posted is from my S&S Super Street 2:1 - for some reason I assumed that was the exhaust you were working on, however oldmike’s link suggested you were using a grand national. So if that’s the case you cant really compare the two, as they are two different exhausts.

It's the one listed under "replacement Parts" for the Super Street, probably the same part in either muffler.

Molto bravo, Lorenzo!! (and thank Fabio from me, too ..)
So, to sum up, and only to confirm for your side, if it is possible...
1) the wonderful screws are STYKFITŽ7
2) when you say "angrever", you're saying a normal metal drill bit, right?
3) You have removed one of the two screws, so the configuration you are going to try is without the dbkiller but with the baffle

Finally, thank you very much, colleagues .. Mchad, Goldmike, MoneyFor ..... and everyone!!. Thank you very much for your help!
I really appreciate your desire to help.

Best regards from Spain!!
