Headman Headers

I want to use these headers(part#68481) but I'm not sure if they work with TBI or TPI. I've seen that most headers work with one or the other. My car has TBI. Will these headrs work on my car?

Save a few bucks...

You can use Hedman part # 68470 with Y-pipe # 17470 if you don't need the A.I.R. and save about $100. I'm using them on my TBI setup.
