I just bought my first TBSS. It's an 07 3SS with a K&N CAI and a HPTuners tune from previous owner. I would like to do some simple mods myself.
1) Switch to electric LS1 fans......do I have to have a retune to do this?
2) Exhaust......remove the muffler or resonator?
3) The HSRK is that something I should do......does that require retune?
4) When I switch the fans do I add the 160 t-stat......retune?

Any and all help would be great! Thanks in advance.
