Mal: these where my thoughts... A screamer pipe is used to reduce turbulence in the exhaust 'caused by the waste-gate, the more free-flowing your exhaust is, the more boost you will naturally get out of an internally gated turbo.

So... Is it possibly to have the Turbo preet described then use a restrictive downpipe/front pipe to limit the boost? This would solve the problem and be more cost effective too (win win situation)? Basically, Instead of having a 2" dump/front pipe with a screamer; Use a 1 3/4" dump/front pipe with no screamer. Does anyone know if this would have the desired effect or not?.... (ie bring the boost down from the 7PSI std to 5PSI)?
