the cheapest clear corners you can buy are probably the APC ones that they have in stock usually at auto zone or discount. i ordered some from arospeed and the APC ones seemed just as nice. just dont put a huge APC sticker on your windsheild.
and i have greddy upper and lower innercooler piping with a brand new greddy type s bov for sale. the piping is polished aluminum and the clamps are still good. will let it go for around 220 or so.
