low mount manifold for stock turbo position rb25det neo

[luminer34neo6trubo]

hello guy, i bought Hypergear turbo and Tomei turbo elbow for stock turbo position. now, i don't want to spend more on changing the setup. So, i m wondering if there's any good low mount exhaust brand. Enlighten me with ur knowledge fellows. i want the best out of it. ty guys

The factory one will flow more then your turbo will

I think @Dose Pipe Sutututu made over 400kw with a modified factory one. 
No point changing unless going to high mount setup.

Listen to these two ^. They speak the truth.

Correct, just had a gate welded to it and kept the OEM divider

I use a modified factory manifold (ported and 45mm external gate) and make 300kw at 16psi.
Found it spools quicker than same turbo on a high mount manifold

Doesn't it logically make some sense that the factory low mount manifolds are going to spool faster than high mount? To generate pressure on the intake side requires backpressure on the exhaust side, the more exhaust volume you have to fill the slower that happens.

Yep, but you often hear internet keyboard experts say they went to a high mount and it gained response, same way you often hear people saying they went higher duration cams and it made the car less laggy lol

Maybe. The factory manifold doesn't have a lot of science in it, so I'd be reasonably open to the possibility of a well designed high mount manifold meeting or beating the spool performance of the stocker. You probably wouldn't be able to have large diameter runners. They'd probably have to be kept at the skinny end of the workable range. Smaller diameter runners would also help with keeping the runner lengths down too, as you wouldn't be building out of such big bends.

Probably a self defeating exercise to do all that for a small runner low power high mount manifold though!
