3SGTE exhaust manifold on 3SGE (gen 2)

Hey guys this is my first post, I'm wondering if the exhaust manifold from a 3SGTE will fit onto the 3SGE. I found a set of custom made headers cheap and hope this'll work as it'll save me a lot of $$$ having them custom made myself.

I'll let someone else go into the specifics (mainly cause I'm tired as hell), but no. It won't fit.

Definitely going to go backwards with a turbo manifold. A tuned turbo manifold is designed to increase gas velocity to make the turbine spin faster, tuned NA headers are designed to maximise flow to improve scavenging of the cylinders.  They're almost opposite purposes.

^ nail on the head,
the only good performance proven aftermarket that come close the construction quality of the oem headers, are the fujuibutsui ones,
you will only move the power band, and why would you want to? its perfect, theres a reason why toyota spend alot on RnD and construct them a certain way, buy a set of cams and drop them in, and spend the rest on a cheap 2.5 inch hi flow cat and cat back, be enough noise coming out of it then,

if anything you will lose performance by the new headers running to hot and without the shields from the standard headers will heat the engine up and oil more, put more heat into the intake piping,
a waste of time and money for 2-5 hp and a little noise

a good quality hi cat and 2.5 inch mandrel bent exhaust cost me 600$ and netted me dyno proven 12 kws
plus gave it a deep growl,

the ported and polished intak runners alone netted me 6kw. 
bit of food for though.

Unfortunately that's what often happens once you start to ditch the stock items, including the header heat shield, and heat jackets on the secondary pipes. Many people also ditch the lower header brace as well that stresses the rest of the system.
And if you don't want it to rust out after a year or so, if you want it to last it should be stainless.
Realistically a well designed full stainless NA aftermarket system might cost up to 2 k
(BTW the stock system is full stainless)
 
And what performance increase could you expect for it?
My guess for all that money and effort on a stock Gen2 motor you might approach the stock Gen3 performance.
 

My first post. Have 1990 NA MR2 with a standard 1 in 2 out muffler, which has seen better days. Would appreciate advice on a suitable replacement that would reduce (eliminate) the tinny/raspy sound that is apparently typical for SW20's.

Bit of a hijack, but I heard the JASMA (toms) Gen 2 headers Stainless are quite a good upgrade?
Anyone to confirm or thoughts on this?
