2zz-ge Trd tuned exhaust manifold

[CoolGT]

Hi all,

Can anyone tell me the difference between the 2zz-ge TRD tuned exhaust manifold and the factory 2zz-ge manifold?

The reason why im asking is because a toyota mechanic has advised me that there will not be much of a difference between the 2 as the factory 2zz-ge already has a pretty good exhaust manifold from factory and the diameter and tubing patterns are quite similiar between the 2.

What im thinking is...if they are similiar, then why did TRD develop a so called "tuned" exhaust manifold for the 2zz-ge?

Would really like to have some light shed on this or if anyone has actually installed a TRD exhaust manifold on a 2zz-ge and found a difference from it.

Thanks heaps!!

the Trd ones have longer primary pipes, and they do give some extra power up high. Work best when some internal work has been done. A few people have seen some gains already using them.

I have trd headers on the garage floor that i would consider selling if i got a reasonable offer. PM me if your interested.

Please pm me your price :)

im guessing your headers are for the 2zz only.

or will they fit the 1zz as well?

the port design on the 1ZZ-FE is different so, no, they won't fit.

I was talking to an exhaust specialist in Perth who has good experience with Toyota parts and he indicated that any gains would be minimal in the absence of other engine and exhaust mods. However, he did not state what these were.
