I have a rattle on my pipes coming from a heatshield and from the pipe hitting the crossmember...didn't happen til the true duals

 

Not trying to hijack, but xdanny510x how are you running the long tube pacesetters here in CA? I want to go with similar ones, but smog issues are stopping me. Any long tube headers for that matter.

PM me with info. if you don't want it on this thread. Thanks.

 

so u think if i switch back to single in dual out i wouldnt have that problem? with the rattling? or should i just go re pipe everything?


oh im just gonna run the long tubes without the cats for a couple months until i get enough money for the turbo then im gonna switch back to shorties with a magnaflow hi flow cats

 

Yep, have this on mine...but then again I was the dummy who put it too close.

 

it could be the heat shield on the motor mount. i had to bend the heat shield away from the header to clear. i dont remember if it was the driver side or passenger side, though.

 

I had the same problem and I just cut my shield back a little bit on the motor mount mine hit the worst on the drivers side but I just cut them both.My pipe is also very close to cross member abought a 1/4 in or so have not drove truck yet thought winters here you know I will find out in the spring (lol) Just buy a bigger cam so you wont here it

 

Check the O2 sensor shield/casing also...thought I remembered reading about someone having one of those rattle...

 

Mine had a vibration/rattle sound only when in reverse. It was coming from the tranny crossmember. We ended up jamming a set of needle nostril pliers (spacer) between the exhaust pipe and the crossmember and then welding up the joint. Problem solved.

 

After I put on Dual Exhaust, everytime i hit a good bump (every five feet in saskatchewan), i would get a knock sound. Went under the truck and it was a bolt from one of the cab-mounts, so i trimmed it to the nut with a dremel.

I could tell it was the one because where it would hit the piped it would leave a mark!

 

Does a guy really need that heat shield? I was looking under there one day, and I wanted to cut it in half, unbolt it, and rip the POS out of there.

The reason I don't think I need it is because my stock muffler is gone and there is only two little bottles there now!
