exhaust manifold designs, getting mine redone Options

[easternpiro1]

hey all, been researching good designs for an exhaust manifold. if some of you dont know, there have been issues with my exhaust manifold from day one and essentially i wasnt happy with its design and quality, (is currently leaking from the flange near the turbo, and wastegate off one runner)so like lagos says: do half assed once do it right the 2nd time.

i will stop there or else i will start a rant. but anyway, anybody got some decent design pics? i want a tubular equal length header , of course with w/g coming from where all 4 runners converge. I got a few ideas from tweak and Pitcelica and a few others.

here's some that i like:

here is a pic of how its currently set up,

here's a couple of pics of my manifold they are all equal length and run onto one before the collector could be made into twin scroll easy as

This looks amazing. i love it
i much prefer equal lenghts



this is my scion tC

Why dont you grab a stock 3rd gen manifold, and use a t3 adapter? Thats going to be more reliable than any tubular manifold (unless you spend big money on one).

im curious of how a log manifold will be more reliable than a equal length one? is it because of the wastegate flange
leaking? or is there something special about the stock manifold. (serious question)

cleanest and best way i think

do you have a wastegate dump tube? or do you just let it open in your engine bay?
