hey guys i just installed my invidia v3 single exhaust and when i was driving i would hear a knocking noise when i go over 60mph or make a left turn. it gets pretty annoying. so i took some pictures and found out what it was.

the piping is knocking against the under body of my car.







does anyone have any ideas of what i should do?

one more thing, i noticed there are two hangers on the muffler section is it just to change angles of the muffler?

 

Modify hangers with cutting and welding or buy exhaust wrap and put enough raps around the pipe so that there is no space between pipe and car thus stopping the banging(<what I would do).


Before I did that I would contact Invidia and tell them about your problem.. They might have a fix for you.

 

hrmm i'll try the exhaust wrap idea, i don't have a welder or anything to modify the hangers

 

The 2 prong exhaust hanger is meant for AP2 rubber hangers

 

possibly buy an ap2 hanger and see if that fixes it

 

whats the difference between ap2 and ap1 hanger?

 

One MIGHT be longer than the other. Its worth a try.

 

AP2 hangers have 3 holes.

AP1 hangers have 2

 

Are the tips centered in the cut outs? I'd try adjusting the hangers and flange bolts to get the proper clearance. You should be able to do it unless it's a used exhaust and it somehow got damaged.

 

i got the exhaust, wasn't damaged or anything. i tried rearranging the bolts and rubber pieces, got it away just a little, but then when i drive it moved back. i ordered some exhaust/header wrap so hopefully that will work.

does anyone know when wrapping the exhaust what to use to keep the wrap on the exhaust? should i buy some stainless steel zip ties? or is there another solution?

thanks
