Hi all
At then end of this week, i am dropping off my bike to be dynotuned by the dealer.
At the moment I have supertrapp rings and end cap on. Dealer says with that set up they have to drill into the exhaust for the "sniffer". I dont want any holes in there, so I am going to change back to the open end that came with the exhaust. (Fatshotzs) for the dyno tune.
After the tune, how much will putting back on the end cap from Supertrapp affect the tune?

Open end cap equals 10 discs. So remove 10 discs and put the open end cap on.
Supertrapp has a helpful tech site.

I have an end cap that I drilled out for the sniffer, then when i'm done with the tune I put the customers endcap without the hole back on. Or I use the Herko blocks.
