Celica GT header on Pontiac Vibe

[Garret]

I accidently bought a Celica GT header for the 00 to 03 and I have a 04 Pontiac Vibe, I didnt realize the mistake until it was too late and the package was already shipped, Is there any way I can make this work for my car? it was a DC header

Will that work for me?

IIRC, the angle of the exhaust side of the header is slightly different....you'll have to modify your stock midpipe flange to fit it

I got the header put on yesterday, is the performance gain of a celica gt header different from the performance gain of a base vibe/matrix header?
