I was wondering if anyone had any sites where i can get Headers/Cold air intake/Exhaust for my 86 celica gts to increase performance. I appreciate it, thanks.

have you tried google or froogle?

Yea, iv'e been searching and havent found much yet... does anyone know any good sites where i can find any of the three?

try ebay they have everything for most celicas except for my 86 gt. there isnt shit for my car but the gts is a totally different story
