i've been looking all over and the only intake that i can find for an 89 240sx is the injen is1910 short ram air intake priced at least $200. i've seen dozens and dozens of auctions (ebay) for cold air intakes going for $30-$40 but only for newer models (91 and +). anyone know where i can find a cheap but effective cold air intake for a reasonable price?
also i've been looking at alot of exhausts. i really like the look of the dual n-1 apexi exhausts but the price... is a little too high. any suggestions on a good cheap exhausts out there i can look into

:help :help :help :help :help :help
*oh yeah, whats the + & -'s between an aluminum and stainless steel exhaust, thanks
