screamer pipe

[roynx79]

does anyone no if you can get a screamer pipe for an evo 4 ??

Yes.

Its called an O2 Dump. Check out the vids on youtube.
Its basicly a modified Turbo elbow and a pipe from the wastegate that vents to the floor.

It sounds Very RUDE!!!!!!
But no good for track action as you will get black flagged.
Local cops also dont like them.

Anyway heres mine incar - With some pops and bangs just to piss people off

Excuse my ignorance but what is a screamer pipe and war purpose does it serve?

 

[e5_dcb]

Its ment to spool the turbo up quicker.
As on a std elbow the wastegate gases and exhaust gases all join in the elbow then go out the exhaust pipe.

With the screamer the wastegate comes out via the pipe so that is ment to reduce the gas turbilance in the elbow.

Or others just like the noise.
I did notice a difference with mine fitted defo span up quicker.

Its an external wastegate... when the actuator activates the exhaust gases normally get expelled down the exhaust. The screamer pipe dumps them out instead of the long exhaust. Basicaly a very short exhaust pipe

Ah your talking about a full blown turbo with external wg.?

My car and the car in the vid are all std Evo turbos with a Modified Elbow.

Picture helps here..

Modified Elbow

Standard Elbow

Thats all it is they dont cost much..

Picture is of Evo 7/8/9 fitments elbow.. The 4/5/6 Elbow is different.

TBH, I have been thinking of getting one of these for my 5, anyone know where sells 'em?

 

[e5_dcb]

No one for the 4/5/6 - Mine was custom made. Later Evos can buy from the states or Ross w.
