I got a Challenger R/T for a day and made a couple kits. I will have a 2 1/2" resonator eliminator kit and a glasspack resonated kit, both will use the stock tips and I also moved the tips out slightly.
I also did a dual tip kit that I will probably have as an option for the V-6's if they want to use the hemi valance or make larger cutouts. We'll see how much Dodoge wants for the tips and if you can or can't buy the clamps seperate.
All my existing V-6 kits will fit the 3.5 but a cut-out will need to be made on both sides.
