Check this thread I am having the same problem I resolved some of it by cable tying the loose cables however I still have a vibration noise which I think is coming from the heat shield on the passenger side. Its not as bad as it was before.

Actually it is an H pipe and yes you want to replace that with the X pipe.

Read my thread on my OBX header install and I talk about the X pipe too.

The OP was also concerned about vibration before any the sensors or cables get damaged (like what happened to me) make sure they are tied down and not banging around.

On the transmission there was a clip that was broken that used to hold the old sensor cable I cable tied it to that and just tied it all the way up through the engine. Like I said I get some noise but it doesn't sound to bad.

No it will make it rasp worse, your best bet is either to get a full cat back system like the ark n2 and ark dts or you could keep the magnaflow xpipe, and get some axel back mufflers to replace the stock ones. MRT 2.0 sounds great and is popular.

The stock mufflers are raspy and with the BBK LT headers it will just amplify the rasp, and like I said earlier check to see if you have anything banging or vibrating on your heat shield and have your x pipe welded (I did that and it helped a little)

Also check to see if anything is hitting the exhaust brace.

Yes, its.different. the bbk one is actually making your rasp problem worse. The magnaflow one isn't a true x pipe. It's actually a muffler that has an x pipe inside. It will quiet your exhaust down and take care of your rasp problem

rtcat, thanks for the link above to your header install, answered all my questions, nice write up and pics/vids.

I was able to do the driver side alone, the pass side was a different story....
