80 series exhaust muffler on 3b with build on turbo

[buschmaster86]

I thought to use a new oem 80series 4.2 td exhaust muffler to quite down my loud 4cylinder 3b engine.

And some straight tru 10cm diameter tube mufflers like this one;



Is this a good idea ?

it probably would depending on if it has packing or not.

if the straight tru mufler has packing or the oem 80 series ?
