Loud exhaust?

ej1love

heat shields

deemee

well it sounds like it's coming from the front, i look under the hood and nothing looks loose

esean93

How bad is it?u sure it's not from under the car?

ej1love

hondas have about 7 heat shields, lol...

deemee

well it's pretty loud and noticeable even if the windows are up and the radio is on

ej1love

well how does it sound? like thin metal?

deemee

yea it sounds like metal is touching each other, could it be something internal?

ej1love

no. jack up ur car look up and down the whole exhaust; all the heat shields are there. even by ur header...

deemee

thanks will do

ej1love

no problem...

If the rattle sounds like an empty beer can bouncing around underneath the car it is definitely a heat shield most likely the one on the cat.

I did the 'hose-clamp mod to my Civic EX'

Buy four hose clamps


open them up so you can attach them together like so


Finished product cost less then $3 and NO MORE RATTLES - FTW!!!!!

Problably your cat heat shield.

ej1love

any luck, OP?

deemee

Exactly it sounds like a rattling beer can lol, thanks THEJB3 for the tip but i didn't get a chance today to look under my car but i will first thing tomorrow

ej1love

well keep us posted...

deemee

Well i finally check out my car and there is no catalytic converter under the car, it's right after the exhaust manifold and the heat shield on it is not rattling... i checked everything under the car but nothing seems to be loose.

However the only thing i noticed was that i was missing one of the rubber hangers for my exhaust, could that be the problem?

ej1love

maybe so...

deemee

lol i know it was an obvious answer but i thought ill just update the thread anyways...
