Since I got my Ws2 muffler with custom 2.5" piping, I hear a noise. Say I'm driving and I let go of the gas completely, I hear a tapping noise coming from the rear of my car as soon as I let go. It also randomly makes a weird crackling noise after the tapping. What can this be? The muffler doesn't seem to be loose.

 

check to see if it is hitting any heatsheilds. I took mine out (on an eg) cuase the joints where hitting, also it sometimes it taps my rear sway bar.

 

I'll try n check it out this weekend when I do my rear lower control arms.

 

Just go under the car and move the exhaust back and forth to see where or if it's hitting anything.

 

I have done that, and dont see it hitting anything...

 

Well I finished doing my LCA, and now I have another rattleling/tapping noise. The exhaust pipe slightly taps the top of my LCA... When im at low rpms, and when it idles it taps. Sounds ugly. What do you guys think I should do?

 

Bend the hanger a little bit so the pipe clears the arm.

 

I could try that. A few other people have also told me something about exhast/heat wrap. How does that work?
And I also figured out that the first tapping noise I heard was actually the same thing. It was the exhaust pipe hitting my oem control arms, but sounded differently.

 

either bend the hanger, or use some foam tape

 

heard heat wrap is bad for exhaust piping. because it holds moisture or somethin.... not too sure but either bend the hangers or u could always have it welded to angle out... this way the piping will be further away from the lca and it will look pretty good... i did it on my dc2 when i had it... and just had it put on my 95 civic and it looks great
