header removal
I just started to remove my old header and had a question about the 2 bottom bolts. it seems to me that it will be easiest to jack the car up and go at it from the underside. I am off on this? and second, is there any need to remove the heat "shroud" around the pipes leading down. Not the heat sheild that covers the top of the headers but the one that raps the pipes under that. thanks in advance
Yes, under the car would be easier. Or take a wrench, put it on, tie a string around it, and pull up from above. Reposition the wrench and repeat.
No, no need to remove the heat shroud. But you should replace those pipes! The downpipe is crushed down to a half-inch at one point! Get the Buschur downpipe and high flow cat!

thanks for the fast reply blacksheepdj, i'll go give that a try. i've heard both good and bad on down pipes and if they work or not on a non turbo lancer. Oh well, one install at a time...
Well, I had the Buschur downpipe as my only exhaust mod. I really noticed the difference.
And there's dyno numbers to back it up!

The Buschur Offroad/Down Pipe combination replaces the equivalent factory units with larger diameter 2.5-in. units. With the complete exhaust system flowing at its maximum, the entire powerband shifted upwards, which means, in layman's terms, that more power would be available at an earlier point in the powerband. Specifically, the extreme low and mid/high to high rpm ranges experienced the most benefit, with increases as high as 7 or 8 hp. Torque also increased with a less dramatic falloff in the high rpm range--this translates into more "pull" for the vehicle at its high-end powerband. Peak horsepower checked out at 111.9 hp, while the torque peaked out at 121.6 lb-ft.
