3" exhaust question

[20Vcqdriver]

Just had my custom exhaust done and after a long chat with Ian Birch of Pipewerx I went for 2 freeflow silencers and 2.5" with 3" downpipe option using mandrel bends as this setup will take 360 to 380bhp max without any serious backpressure issues and no boominess...
If you're aiming for more than this then you'll need 3" all the way...

Mines 3" from turbo back, 2 small straight through boxes, a bit boomy but on wot sound good

The downpipe is the same from the turbo to lambda bung in RS2 and ABY?

Because my engineer says to use the original part of the DP from the turbo to the lambda bung.

It's a good idea o is better do it all in 3"?

Cheers

best to get a FULL 3" because the oem rs2 DP is 2.75"

[MarT2]

But it's 2.75" from the turbo or from the lambda bung?

[Jamo]

That's just lazy downpipe building he needs a 2.5 to 3" transition

If you go ahead with the 3" exhaust system - you will be revisiting it within the coming months when the continual ringing in oyur ears - and inability to hold conversations over long journeys will become a drag - other than that - it will sound awesome!!!!!!
