New Dinan exhaust and TB installed!

[DinanX5]

Finally got the Dinan exhaust and throttle body installed on my 2005 4.4 on Friday!! Here's my report:

Power: Noticeably more torque all through the RPM range. When driving around in D or DS auto mode, trans. seems to require a downshift less often (it will find adequate power even at lower RPMs in 6th gear)

Sound: Wow! The sound is much more aggressive. Heads turn when it's started up... not sure if it's throatier than a 4.8/4.6, but I imagine it probably is. It has a nice rumble at idle and during heavy acceleration, but it's actually pretty civil - barely noticeable over stock - under conservative throttle pressure. My car-enthusiast friends noticed the difference in sound immediately, of course. But my wife did NOT notice, which was fortunate b/c I didn't mention to her that the Dinan mods were being done; I only mentioned getting the oil changed
[BTW, the next day when we hopped in the car and I turned the key, and the new exhaust announced it's presence with an authoritative BRAP! I just held my breath and looked at her out of the corner of my eye waiting for the expression change and the big "what did you do?!" question... but it never came! Somehow, amazingly, she just didn't notice the difference.]

Looks: Big improvement. The pipes are larger diameter, longer, and chrome, so they stand out much more than the stock black sport pipes. I really love the new look.

Gas Mileage: I was a little worried about this with state of the current gas prices, but I was pleasantly surprised. In fact, I averaged 24.7 MPG on my way back from the Poconos to Hoboken last night, which is considerably BETTER than I've ever gotten before. [The trip is about 100 miles - half interstate, 1/4 two lanes mountain roads, 1/4 4-lane secondary highways with stoplights.] I may have gone a little easier on the gas than usual, but the best I've ever done previously on that trip was about 22.5

Overall I'm very happy with the mods
