Do I have uprated downpipes or are they all two into one. I looked at my downpipes when fitting cat replacement pipes and they have two outlets on the turbo side one for the wastegate and one for the exhaust. Is that normal or are they uprated ?

 

All help greatly appreciated !

Olly You have two downpipes , one for each Turbo outlet

 

So are you saying you have 4 :confused: or just two (which is normal)

I have four, as it exits the turbo on each side it has two pipes each side (downpipes) going into a single pipe which joins onto the test pipes !

 

I thought they maybe upgraded and possibly the turbos as well ?

 

Olly.

does it look similar to this ?

 

 

taken from tt.net:

 

"This is also known as divorced waste gates

The reason this type of down pipe works better is because the exhaust coming off the turbo wheel is spinning extremely fast and whipping in a circle….If the exhaust comes off the turbo wheel and inters a much larger area it becomes more turbulent slowing the exhaust velocity….also when the wastegate opens the two turbulent exhaust gases fight each other causing more turbulence."

That looks like the babies !!! Do they come with uprated turbos normally or do people uprate the downpipes on their own, (wishfull thinking that I have a set of uprated turbos !)

you get them from Greg Dupree in the STATES, you need to purchase turbos of your choice the, depending on the flange they have (4 hole or 5 hole) you purchase the downpipes.

So I could very well have uprated tub's !!! How can I tell for sure I can get them from underneath but whats the standard a/r.
