Nope That is why they fart through the intake when the butterfly is slammed shut! All the excess boost comes back, out the intake.

No one was right..... loose nuts on engine side of cat!!! Actually they were the WRONG nuts.....prob from the headgasket repair a year ago......but I can't prove that.....but it wasn't the first time I found shoddy work from that repair. Many body bolts missing/loose from lifting the cab..... they yanked the plastic push screws from the rubber air dam under the grill.....Don't think I'll be using THAT dealer again.
Not what I heard.... mine was really a SCREECHING noise.....like a metal to metal scraping sound. But hey, it COULD be a beginning of what I had... easy enough to check...crawl under and try to wiggle the CAT pipe BEFORE it goes into the cat. Oh...be dang sure the pipe is COLD!
