Hey Doggy,
Am I right in thinking that, in your photo, that's an original header with the heatshield removed?

BTW: Mynzeyes "header how to" method using a 7AFE Corolla header is the only way us 7AFE'rs can go. (A 7AFE header specifically for a Celica does not exist).
...that is unless you know someone that can make one to measure.

I have come to the conclusion that the header is the last thing I'll do.
Cost / Gains = minimal.
Let's face it, japonese technolgy aint bad.

The major restriction on our cars is the catalytic converter (resonator), so change that and add a decent muffler or get a full cat-back system.

I would like a Greddy SP cat-back system but I'd have to find it first and then I'd have to import from the States and this will probably cost me way too much €€€€'s, so I've been looking around here in Europe to see what's available. (Not a great deal).

The only cat-back system available here is made by Supersprint...and it aint bad, by the looks of it, figures, etc.., it has better hp gains than the Greddy.

Another option may be to just buy the Supersprint cat. and then add a muffler (UK - Mongoose or German - Remus).
