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!!
