[quote=tblake]hey all, over the summer, I plan on doing a lot of little appearence upgrades to my car. I plan on chroming the bottom of the doors, dual exhaust with chrome tips, my friend has a totaled LS and she said I could have the rims and tires, and I plan on window tinting and pinstriping. One more thing I would like to do is get sort of an outline for my tail/brake lights. maybe you have seen them before, or know what I'm talking about? I thought maybe some long lost company somewhere would still make some sort of colored vinyl sticker to stick to my tail lights. Anyone know of any? or do I have to paint? whats the best and easiest way of doing that. Any other ideas of exterior add-ons? I want my car not only to look good going fast but also standing still. Thank you. Also, the dual exhaust will open up my exhaust, I was wondering if anyone has ever bored out the heads on the 3100sfi. Is it worth doing? increase a little more torque and a few horses? I was thinking about buying a couple used heads, regrinding the seats and valves, and see if there is anywhere they could be bored out, so I thought I'd ask you guys before i waste money on nothing. thanks[/QUO ************ Bored out you mean porting the heads, this can be a very skill oriented task, just opening the ports can hurt performance, the breathing of this engine is limited by the camshaft design, you could do a 3 angle valve job, gasket match the the ports and maybe smooth out some roughness in the castings, but I would not go further, tru duals might gain some power at the highest rpms, but again no effect under normal driving.
