While I was surfing around researching pipes and pricing I came across a thread in another forum where it seemed to be recommended to wrap the up pipes and turbo with header wrap with the idea it would aid substantially in turbo spooling and reducing greatly turbo lag. I haven't seen much of this info on this forum so just throwing it out there to see who may have done this and what kind of results it yielded. is it worth the $100 for header wrap and the time to do it? BTW I have ordered the BG up pipe kit for the 99-03 7.3 for reference.
