I have another question for you.

If I'm upgrading to a 3" downpipe and catback exhaust for bpu+++ but I plan to go to APU later on, would a 4" catback exhaust and downpipe be better at APU levels? if so, would I be able to skip the 3" downpipe and exhaust and go right to the 4" at bpu/bpu+++ so I don't have to buy two exhausts and two downpipes?
