I ended up buying a 1-1/4” rubber grommet kit, cutting a hole and installed the JB4 inside the car and preserved the sound tube. Pretty easy! Also, is there a reason to delete it and is there a kit to do so?

That sounds clean, got any pictures handy? Mostly deleted when people upgrade their Y pipe.

Depends on the Map used but we usually see about 60whp/80wtq increase on map3 with 93 octane.

I do not have a photo but I can tell you all I did was spend $5 on Dorman 90305 from Advance Auto Parts and used a 1-1/8” Lenox hole saw. I did it from inside the car and it worked like a charm
