Essentially the title. I just replaced the factory muffler on my '23 PR with a performance MagnaFlow muffler and I noticed a bit of a different shifting pattern (I'm assuming due to less back pressure). It's not harsh or bad in any way, I just want to get opinions on if long-term it will have any negative effects on the transmission.
