Vibrating exhaust sheilds@idle???

[hotrodsrx]

My 03 Rx-1 has an bad rattle/vibration at idle. I read a post on here a while back and someone stated that it wasn't a heat shield but the clamps and gaskets for the exhaust.

I pulled the gas tank last night and it looks like the clamps on the manifolds are tight. There dosen't seem to be any soot indicating a leak either.

Can someone give me an idea where to look next?

check for loose exhaust shields above the track under the tunnel. remove them if they are loose. According to others they are not needed, and can fall off and jam at the front of the track box.

Also, make sure the rattle you hear isn't just the gear reduction, this noise will be just behind the primary clutch. If that is the noise, sync the carbs and adjust Idle a bit higher like 1550 rpm and it should get rid of the majority of that noise. Good Luck

The first thing my husband did to my rx-1 was cut those exhaust shields off. No problems at all without them and no more rattling noise.

Thanks for the help and wish me luck I'm dangerous with my sawzall!!!!!

I'll sync the carbs as well. I've got a ECP going this weekend.

Do the clamps were the flex pipe attackes to the y pipe move? They should not be able to turn around otherwise the donuts are burnt out. It's hard to tell unless you know what to look for. I almost thought mine were fine till further inspection.

I just had to change the donuts on mine up off the flex pipes,2600 miles and the 2 outside ones where shot. you'll notice the clamps will be turned to the side not staight across if there loose

Dropped the suspension tonight and found the heat shield on one of the y-pipes loose so I took them out.

All the clamps are nice and tight so I guess I'll put it back together.

Thanks for the help!!!!!!!!
