screamer or not?????????????

[xxxadzxxx]

just ordered a new turbo for my s12, so do i fit a screamer pipe? my car is mainly a track car so i'm ltd to 98db. will a screamer be too loud. this is my 1st turbo car so i apolagise if i'm asking stupid questions??

[xxxadzxxx]

also do anyone know of a aftermarket exhaust manifold? or if a ca18det will fit?

CNHSS1 races his SS1 reliant and that has a external waste-gate, pm him.

The CA18DET exhaust mani wont fit as a straight swap but an aftermarket one can be modded to fit. CNHSS1 did this to his and i am sure there are pictures somewhere
KEN made his own mani from scratch with good results

i got a top mount made to, rich k has it, perhaps he could put some pics up,

above is the original thread, although some of the pics have been deleted, but work your way through.
Ext wastegate is a pain in terms of fabrication but the boost doesnt spike and is super stable. with the extra gasses exiting to the atmosphere (rather than rejoining the main exh) theres less back pressure restriction meaning a 2.5" system is fine for near 300hp. with internal wastegate it would probably need a 3" system which would be tight to fit in my car.

Anyway to use an external without gettings the chavs all excited though ?

What is a screamer pipe anyway ?

I'll stick them up later, dont think Rich is on much at the moment

ok so would it be possible to silence the external wastegate or does this defete the object. but it needs to say under 98db I'm not looking for serious power as in my opinion 200 whp and car weight @ 1000kg this would make he car both reliable and fun.

Hi,

I've got a stainless screamer pipe for sale will fit t25-t28 turbo, complete with gaskets. Only used for a couple of months and is as new condition.

Selling as breaking engine, £30 posted.
