hi i have a 99 ws6, so far i have the Slp lid, slp bellow, and slp mass airflow sensor. i also want to do my throttle body and manifold. is it worth doing that or no? and also if i do should i get the SLP ls6 manifold or go with the F.A.S.T. manifold with the 78mm or 90 mm throttle body, please help me and explain the difference. thanks alot

 

Well by reading the first three posts this morning I see that you havn't done much research before buying aftermarket parts for your car. Don't believe all the adds you read in car mags. You should spend some time here you'll learn alot. You really like SLP,huh?
