Do mechanics not advise people to do this when fitting Turbo back exhausts? Would have thought it would help cover them should the engine go pop!

Don't drive this thing hard until you get it tuned.. It will have shit fuel economy, probably not drive the best, could throw a CEL and could go snap crackle and pop.

Then when you get headers later your retune cost will be less anyway. Or scrape the barrel now and get headers at the same time as the tune.
