Default Up pipes??????

Help!

I've recently replaced the standard up pipe for a 2.5 inch bore on my 1995 RA. Will this effect the boost and power, should go back to a 2 inch bore?

Can anyone dispel this myth for me,

Thanks - adb2227

fitting the 2.5 inch up pipe you affect the spool of the turbo, so standard size is best but is not 2inch (50mm) it is more like 42mm.
