Doesn't Katech offer a 95mm to 95mm straight adapter? Why would there be a step if the inlet and TB are both 95mm? If anything, the 95 to 87 adapter would create turbulence. Unless you've taken that tapered adapter and port matched it to the inlet as well?
I am curious on what gains are left on the table by *not* porting the inlet and just using a 95mm to 87mm adapter. You still get a jump in cross sectional gain jumping from a 87mm TB to a 95mm TB, even if the snout is 87mm. At minimum throttle response will be much improved.
