Cconnj - $180 for the Cold Air intake
Comptech Header & Downpipe 97 - 98 CL 3.0L $1,200.00 (these headers are very rare and I can gaurantee you'd be the only one with these, but the price is very steep, it has a 25+ hp gain though)
exhaust wise i can get you a universal apexi n1 exhaust for $215.00, sorry they dont make cat-back, but you can always buy a universal and do custom piping.
