So this is my second thread. When I get a good working camera I'll take pics of my car. Anyway, what would this community suggest that my first few mods for my silver '07 6i be. I have tinted windows and new mufflers. I was thinking of HID headlights but I heard you have to take off your front bumper to get it done. Cold air intake? I'm looking to add a littler more performance/horsepower. As far as I know the 6i has 165/170 hp stock. What could add 30/35 HP? CAI add about what, 10? Anything else would be welcome. Thanks. (Oh yeah, I guess performance chips do not work)

Your a little off on your numbers there but it's ok cause your a noob. Get a cai which will increase hp by 4 or 5 and headers with a full exhaust if you want about fifteen hp. You probably aren't going to get more than 25 with just bolt on mods. Get a turbo if you want some real hp. Also go with the HID lights. Get them from ddm tuning. They're only 45 bucks with shipping and they're well worth it. The bumper takes like fifteen minutes to take off by the way. If you plan on getting an extra 30/35 hp then you better be willing to take your car apart.

About how much generally will a decent exhaust system with headers cost? And labor?

The 2007 6i only had 156hp. Gaining 30hp or more at the crank MIGHT be possible, but putting 30 more hp at the wheels with just bolt-on mods is damn near impossible.

Headers will run you $300-$400, I think, and the full exhaust will probably be about the same if you have it custom made at a shop. I don't think anybody makes a pre-packaged full exhaust systems. There are pre-packaged catbacks, but those don't give any power increases. IIRC, even the full exhaust might not give that much of a power increase.

Taking off the bumper for the HID install is ridiculously easy, so don't worry about that.

So if I go to DDM tuning, as listed above and Here, What all do I need to purchase. Harness, Adaptor, Error Elim? I like the blue tint so I'm thinking of going with the 35 watt 8-10K. Thanks.

156 HP does not seem like much but it is fun to drive. Although, All I have ever driven were an F-150, Explorer and Ranger.

all you need from ddm is the hid kit. nothing extra. everything you need is included in the kit.
