Just an update on this mod after a little road trip. Not a big one just did about a 1000 miles but have a total of about 2400 miles since the mod. I'm extremly happy with this setup. I installed mini cats when the DP's went on and got a code after about 50 miles or so. Reset with the JB4 and have not had another pop up since. Better than I expected as WONT TAP had said these devices typically don't work on these cars. If they pop up though no big deal but I am happy with not having to mess with a code on every start up. Car sounds great and with the TB it feels better at WOT. Can't wait to get the carbon air intake next. If that is as much of a bump up as what I just did this car will be right in the sweet spot for me! I also wanted to comment on the driveability on the highway. In tour mode it's not much of a change especially at highway speeds. Only on normal driving acceleration is there a slight drone from like 2.9k/rpm to like 3.1k/rpm. At highway speeds it is a nice drive without any annoying sounds to bother with the car eating up miles in a comfortable manner. My wife who is not a fan of me driving fast and could care less how the car sounds said when I asked if she noticed a difference on the trip "not at all" she definately noticed the difference in sound when I'm driving fast though. I was a bit apprehensive about doing this but so glad I did. Also a big tip of the cap to Tap Out for all their help in answering questions. Where I live it seems next to impossible to find anyone willing to work on these cars Let alone be able to answer any questions. I was thankful for all their info they included with all the parts for installation that I included with the parts for my mechanic/tuner. Hope this helps someone else that may be considering some or all of these mods. Basically I have the Tapout blue belt with the addition of a muffler delete.
