I previously had a spires switchable exhaust on my xkr and I think I had it in quiet mode perhaps 0.3 percent of the time in three years of ownership but it was a very good system with just minimal drone at very very low revs, hence I was thinking to not bother with switchable this time
I have seen the armytrix and gt haus ones but they are quite expensive over 3k? Maybe if a used one comes up I’ll go for it
