Just had the full BAVSound system added, including soundproofing the sub area. I have not picked it up yet, but it is ready. My audio guy says it is improved, but would be far better if I added a JL Audio 12-channel amp with signal processor and then retuned the system from scratch. Ordered Eventuri intake, ETS catted downpipe (to replace the catless one I have on now), and Boost Logic titanium exhaust with black tips and valved option. Once new parts are added, I assume it will require further tuning. Finally, TJ Hunt rear wing with CF center supposed to come in next week. Will report back.
