Yes that's the idea.
There might even be a "bung" in the manifold already so worth a careful look - you win some !
If it is fitted with an EGT gauge ( thermocouple ) then you could use that for experimenting - best
location would be in the manifold/turbo flange
Exactly what pressure is acceptable is VERY difficult to answer - so your looking for a trend and feel.
Decrease in back pressure is good even if there's no change in feel - but with the significant fold over
on the exhaust wheel trailing edges ( especially when compared with the suzisport unit ) it would seem to have merit.
If it works out you could always have the stock wheel axially ground ( take some of the "fold" off )
assuming of course there aren't irreplaceable. Still that's getting a bit on the serious side but once
again been done before.
