I agree with GWP. The muffler delete will only make it louder... it won't impact the tune. It would be similar to running electric cutouts but without the sound adjustability. There are lots of videos on youtube that show dyno runs and tunes with cutouts open and closed and the tune is not impacted... for that matter, the hp and torque usually don't change either.

But like GWP said... it's going to be loud. If you do the muffler delete, I recommend clamping them on so you can put the mufflers back on if it is too much to handle on a daily basis. I run electric cutouts for that very reason. I love a loud V8 with LTs, offroad pipes and nasty cam, but sometimes you need to quiet it down for the neighborhood!
