MBRP Downpipe Noisy?

How much in cab noise does swapping to a new downpipe add? My cab is unbearably loud now. Just wondering how much the noise goes up, or if something is wrong.

Make sure it isn't touching the firewall anywhere.

Are you guys tearing out the heat shield on the lower half of the pipe? It seems to rub a bit there. Or rather the clearance is very tight and I think when the engine rocks from startup or torquing, it actually comes in contact with the heat shield.

Mine is pretty quiet, the pipe fits well, the only noise I had was when it was hitting the firewall, but after massaging it , the engine is actually a little quieter with the mbrp pipe and exhaust.

That's what it is: rubbing against the cab. I took it all apart, bent the cab back, put it together 3 more times, cut an inch off the downpipe, and it still makes noise when in reverse and during some highway cruising.

This MBRP downpipe sucks dick. First and last time I order something from them. Going to take it apart again one more time before I order a new one.
