I have a 2003 Vibe and have been searching for new performance headers for quite a while now. DC Sports stopped making the headers for the 03 Vibe base.
I found a used 2001 Celica GT header on ebay. Both cars share the same engine, 1ZZ FE. My question is, will a 01 Celica GT header fit on the vibe without modification and will it be an effective performance upgrade? Effective as in exhaust gas will leave the engine faster. I already know HP gain will be minimal.

The only difference that stands out to me is how thin the header tubes are compared to an actual performance header.
Thank you
