my cat wont stop rattling...i need ot make it stop...any suggestions (perferably tings i can do in my drive way

 

Wrap the bitch in exhaust wrap........20 bux from summitracing.com

 

punch it out . it sounds like the honey combs inside are broken .

 

take the heat shield off and look to see if there's any rocks stuck up there. that's pretty common

 

my does the same thing....but it only started when i gutted it out......oops....

 

hey i got an hx too...98.....what do u have done to urs..im planing on doing ome mods soon? what brands did u go with for intake, and exsaust...if u got them?

 

My heatshield had rusted part way off and that was what was rattling on my cat. Get under the car and check it out.

 

There is a 99% chance that the mounting holes on the cat have just rusted out, so it's rattling. Get a pair of vise grips and rip it out, you dont need it anyway. This is extremely common. I hope this helps. Later!

 

I have a DAC intake.
DC Sports 4-2-1 ceramic header (whatever.....)
Unknown cat-back pulled it from my EX.

If you really want to keep the HX, get an EX intake manifold (Type R of the D series). Get yourself a EX transmission (stronger and higher gearing). DON"T get an EX head. The cam specs are better on the HX. I am looking into re-sleeving the block to 79mm. Custom pistons and rods. And then after that port and polish the head and other things.

Susepension: Neuspeed Sport springs, stock shocks, APC rear strut bar (hey it was 40 bux). Wiating to go in. SI front sway, Type R rear sway.

 

think ur cat. has seen its last days..get another or get bust d

 

I've had rattling cats on both my Civics. In my experience it's usually just the heat shield. the mounting holes rust out and it vibrates. Always finds it's favorite frequency at about idle to really embarass you at stoplights.

just remove the heat-shield. Keep the cat and don't gut it. they're there for a reason.

 

if its not the heatshield then its the honeycomb, if it is then buy a new one

 

That surely got me rollin' in laughter!!!! Been there, done that!!! LOL!!!

 

The same thing happened to me, it was so bad I drove our Suburban until I had time to fix it just because I didn't want anyone to think I wasn't taking care of my honda.

 

Are you sure it's not your heat shield? I thought it was my cat making that annoying sound, but it just turned out to be the heat shield.
