I had my exhaust fixed(mine was rusted thru) about a week ago. Anyways what we did was cut off part of my midpipe, and then attach a new part that was cut off from another midpipe, now my car is making a metal on metal noise between 3200 and 3300 rpm ,and then an even louder one from 3500 to 3800 rpm. All other rpms it doesn't make a noise.


Now I'm thinking its the clamps that are making that noise from vibratoin with the midpipe...anyone have any suggestions on how to fix this?

I was thinking of wrapping the exhaust with some rags and then using the clamps that way maybe the rag will dissipiate the vibration but I dunno if that can cause a fire or something, anyone have any suggestions?

oh yeah forgot to add when I was reassembling the midpipe/muffler I didn't use a spring on one of the bolts, ended up not using the oem bolts/nuts because they were broken in .

could the lack of a gasket be the source?

 

my lil bros car makes that noise. check to see if the bolts from the cat are tight.

 

the bolts by the cat are rusted to the cat, which is why I had to cut my exhaust and to cut a almost new bpipe just to get it work, I'll tighten the bolts tho

 

problem turned out, that one of the bolts holding the heatshield around the cat, was missing, replaced it, and bam no more noise
