What ever you buy (especially if from ebay!!!!!!)
make sure it is for a celica and not a corolla (7afe)

i bought mine from ebay and they came up 8 inches or so too short to bolt up to the front of the cat.
turned out ok though because my bolts on the cat were rusted and rounded off.
i just cut the downpipe and welded on a flange and bolted the 2 together.
it looks ghetto as hell but flows well and sounds awesome.
i'm running a 20 dollar thrush turbo muffler from advance auto because i wanted something to growl under load but be quiet when idling and sitting in traffic.
it sounds awesome.

isnt stock piping on a gt 2.25?

no. it is 1.75 I think.. Maybe smaller

the ebay surewinproducts says that their header's outlet is 2.25" and directly bolts onto the stock downpipe. So gt's should have 2.25" stock piping? I thought that st's had 1.75".

I got a custom exhaust done that is 2.5 and it was way bigger than the stock exhaust. So I know that it wasn't 2.25

Ok. There is another header on ebay that says the outlet it 2.5". http://cgi.ebay.com/ebaymotors/Toyota-Celi...A1%7C240%3A1318 Has anyone used this header? I know the header from surewinproducts fits without modifying anything, but its outlet is 2.25". Would it be better to have the 2.5" outlet on the header or just 2.25"?
