My car has a horrible exhaust problem, makes noise. Even louder as the speed increases. Also it puts out mass heat. My trunk got so hot that the carpet inside of it started to melt. Im not sure if its...


Well it sounds like either the muffler itself has a rupture in the outer shell or the exhaust pipe going into the inlet may have a hole or a bad weld (or loose clamp if it's not welded in place) as to the heat shield you'ld just need to raise & support the vehicle and really inspect exhaust to pinpoint problem and see if the heat shield has been replaced too. I'd imagine the top of the muffler has blown out and all that heat is hitting the trunk pan and melting your carpet

Vibrating noise coming from the muffler. It seems like there is a loose part, but I have examined and found nothing. Any suggestions would be greatly appreciated.


If it sounds "tinny" it is most likely the muffler heat shield. Check the exhaust and muffler clearance to all heat shields to make sure there is at least a 1 inch clearance between the components. Make sure no hangers are broken that would allow the exhaust to move about.
good luck

Exhaust issue


Most likely the heat shield has corroded off and is just sitting on top of the muffler or Catalytic converter. Regardless you can remove the shield and still run the the Xterra without any problems, the OEM muffler came with a heat shield as to the after market mufflers don't have one. The Catalytic converter also has a shield and you can remove it also as the Xterra has a heat shield on the floor board it self. Most exhaust shop if honest will tell you to just remove the rattling shield if there is no exhaust leaks or no Check engine light on that monitor's the Catalytic converter's performance.
A muffler shop if shady may advise you to replace the Catalytic converter and that can go for up to and beyond $400.00, so as long as there is no leaks or check engine light on. Go right ahead and remove the rattling shield.

Loose heat shield


Most likely it's a heat sheild on the converter, maybe the muffler. 1 on top and 1 on the bottom. The heat sheild is welded to the converter, over time they rust away, around the welds. You can use a large diameter worm gear clamp to keep the heat sheild from rattling. The sheilds are in place so if you drive over grass, the heat from the converter won't ignite the grass.

When running metalic vibrating sound from muffler


Hi there
Just take it into the exhaust people and tell them that you need a new muffler ONLY. welded into the place of old one as all your problem is the BAFFEL plates have come loose and the welding is only spot welded and isent any good So a new muffler is ALL YOU WANT

Metal piece hanging in middle of undercarriage just behind wheels


It's likely the heat shield for the catalytic converter. There's really no repair for it. Mechanics won't usually spot weld it and they can't remove it. Apart from a little rattle now and then, there's really nothing to worry about.

Exhaust pipe rattles when car idles. Had muffler


Check the heat shield on the Catalytic Converter, after a few years they start to rust off and rattle. Crawl under the Pathfinder and bang along the Converter and muffler area and see where it's coming from.   Good chances are, it's from the heat shield since you already had everything changed from the Cat back.
Good luck and hope this helps.

Yes, it will cause you no problems. Just avoid excessively long idling.

Vibration/rattle underneat when starting/accelerating


I don't think its actually a problem, its just because the engine is cold, i don't think you have something to wary about.
