Also, why 3”?

3” to go for gains while keeping it quiet with the rest of the setup I had planned out initially. I was worried that going uncatted UEL even with the UQFP with either cat/resonator or dual resonator combo would be too loud for me cause I’m pretty set on the Perrin 3” resonated. I’m also hesitant cause of CEL, even though I am going to end up with an OFT tune or Delicious tune which I heard can take out the CEL. If the cats are that susceptible to blowing out in the header, then maybe cat/resonator would be the way with catless upfront.
