Since I am getting so much better performance I think I might go all the way in the exhaust work. Also I forgot to mention my mileage from the homelink thing states 15.2mpg for about half a year now, and after I changed the mufflers, and about 50 miles driving it went up to like 17, so I think a less restrictive muffler also saves gas, or restores it in my point of view. I thought it was a lie that they said 21-30mpg in the official epa, so I though around 15 or 16mpg it was normal. But I never asked anyone else.

yeah go with the second one if you have the 3400, thats the one i have and i love it. makes the car sound alot better and gets a little better performance. and keep updated on that electric turbo, id like to know how it works out for you. but the one for the 3800 wont work for the 3400, make sure you dont have emmisions test in your area and get the off road DP, but its gonna set a code off. for me it was the PO140 maybe it was the PO 120.
