Exhaust Manifold
 

Does anyone know which aftermarket Headers/exhaust manifold would work with the SOHO Stage 2.5 turbo kit? Or is my only option custom? also how much of a restriction is the stock exhaust manifold?

Call them up. I have no idea. They need to be upgraded for 800whp or above. Somewhere around there.

Don’t need so when you can get these. This is what alpha Z runs on his car. Schedule 10 metal. Worth the money. Alpha Z34 runs this. Don’t get ripped off by SoHo’s junk

The "new" Z1 headers with HR/VHR flanges should fit if it mates to the OEM manifolds.

Looks expensive! lol

I'm going to go check them out. thank you.

No more then what soho is selling there’s for. And not much more expensive then the over price z1 shorties. You’re going to spend anyway

Still trying to wrap my head around how they've raised the price ~$700 in a few years :shakes head:

Because they aren’t z1 anymore

I called Nik @ Soho... i guess they have a new exhaust manifold that they are selling now that isnt on their website.. its going for 2k. that seems like a lot to me.. I know im pinching pennies... but im already 40k in the hole on the build.. i'd like to save money where i can if possible. Elmo 370z those look really really nice.. and if they match to where the stock ones end they may be worth considering.. especially if they're cheaper than soho. What exactly am i looking for when upgrading the exhaust manifold? there are soo many options for cheaper... are the metals trash or what? Do the shorties give you more room in the engine bay? my passenger side is stuffed full of uppipes and downpipes lol.

Where were they purchased from so i can look them up?

What do you mean? I know the DE-flanged headers were never really Z1's design from the start since they were based on the Momentum headers

Contact switchback racing. They built them.

Price will be around the same, the metal switchback uses is a schedule 10 SS. Won’t ever have to worry about cracking
