True dual Y-pipe

[maz77]

new or used in very good condition

[rtbiscuit]

is that not a contradiction in terms?

 

a y pipe connects 2 pipes into 1. a true dual keeps both pipes separate.

[maz77]

your right in away but its just to indicate the wider bore y pipes used with the true dual systems

some y pipes are actually true dual but still called y pipes like the injen's for example

[rtbiscuit]

i'm confussed

 

are you looking for 2 into 1 but bigger bore

 

or 2 in to 2 for a true "true dual"

 

sorry if it s silly questions, its late and my brain don't work.

Maz, I think you need to let they traders know which exhaust it will be used with

Look at the true dual from Borla and the setup a group buy

it will be a custom joby chris

thanks sara, I am after a 2 to 2 Y-pipe though.

an X-pipe then

look at the Y-pipe in this injen exhaust

What are you trying to achieve?

 

If the exhaust is gonna be a custom job then just get them to fab a 2-2 piece for you

Thats what I'd do. Same diameter all the way then

I wouldn't even bother the y piece tbh. I'd just run 2 pipes from the cats

I thought there was something to be had from the cross flow of combining both sides. Cant remember where I read it mind

Probably on my350

that would delete the flexi's making it more prone to cracks

Not really. APS & Invidia both use that design.

 

Any decent custom exhaust place would be able to do it

[IanS16]

I would have thought adding an engine damper would eliminate the need for flexipiping

[maz77]

to put things into prespective guys.

the idea was to utilise the end pipes of the K1 exhaust.

 

plan:

change y-pipe.

get custom made twin middle pipe.

 

I wasn't planning on getting a full custom exhaust.

 

in the picture below you will see the single middle pipe the K1 uses.

it looked easy enough for me (apart from clearing the diff issues) to change that to 2 parallel pipe. add to it a 2 to 2 y-pipe and I would have a true dual

 

 

the question is, would that loose me some top end torque in NA form or not?
