Any BIC DDP owners out there that could shed some light on whether getting the flex section and ceramic coating are worth it.  Couldn't I just give it a couple coats of high temp paint and some heat wrap?  Is the flex section really necessary for fitment issues?  <---I care more about this than the latter question.  I'm trying to get a downpipe and exhaust for under 1K but still have quality. Thx guys.
