Question Removing heat shields...is this ok?

I have a couple exhaust rattles. So I removed all my exhaust heat shields. Is this ok to do so? I took off the three from the mid-pipe all the way to the muffler.

I took mine off over a year ago and have not had any problems at all.

I wouldn't for no real reason.
If you do a lot of highway driving - no problem.
If a lot of city and traffic jams you won't be too happy.

Albert is correct.

Wouldn't it make more since to try to find how to solve the rattle than to just get rid of what is making the rattle?

Just a thought

Why, will this harm my car at all? I was thinking about putting the one over the mid-pipe back on only because that one protects the drive shaft.

the HEAT shield is their for a reason. It protects the rest of your car from the 1300 degree heat that comes from the engine. By removing this it doesn't mean that anything will happen but something could potentially happen...like getting a smelly trunk from melting stuff.

Or at least this is my understanding...take it for what its worth

i believe (someone correct me if im wrong!) the heat shields near catalytic converters are there to retain heat and get the temperature up. the platinum compounds cant scrub SOx and NOx at low temperatures so you may one day have a CEL related to it

I have a CEL fix in that cat, so I think it would be ok. Oh, and I forgot to mention that I have a high flow cat. So its basically straight through.

hey! i was looking for a high flow cat - what do you have? think you could give us a little review - and a price/place where you got it? how exactly did you install it (w/ federal emissions laws?) and how does the cel fix work?

thnx!

The hotter the exhaust gases the better. Never really thought of the heat shields keeping heat in the cat., but your point seems valid. That's why companies ceramic coat exhaust components, at least the good ones. The ceramic insulates the pipe, trapping the exhaust gases in, which keeps them hot and doesn't allow dissipation of heat. Hot gases flow better than cold and we want the exhaust gases out as quickly as we can. However, this is arguable, but I think 2-3 psi backpressure is optimal on N/A vehicle. My friend just re-packed the Vance & Hines on his sport bike and said he has noticeable improvement on the low end.

Jejunum: I got my high flow cat through ILP performance who is no longer in business. They custom fit the cat making a whole new pipe. It costed around$200 bucks for the whole high flow cat pipe.

it woulda been better to leave the shields on, esp. around the cat becuase if your ever under hte car when its still running or just shut off, they are a lot cooler than the exhuast pipes themselves..

and yes, they also prevent some stuff from hitting hte drive-shaft.
mine rattled back in teh day, but i just bent them where i saw they were hitting other parts and now they are more rigid, so they dont really felx, and are silent as can be, figuring out the one was comming from back by the muffler was kinda a bitch, but i got it all sorted out.

My rear shifter mount's bushing heat cracked with the shields in place- without them, it could just happen faster. A poly bushing would of course eliminate the worry.

(I'm refering to the small metal housed 2-hole bushing that bolts behind the shifter handle, not the large, 2-piece round one)

Well, I figured out my rattle. Turns out it was my O2 sensor going into my cat. Its seems it wasnt tight and was just rattle around. But I am going to put on my mid-pipe heat shield. Leave the rear ones off though. Thanks guys for all your wisdom!

So, is it ok to remove the actual shield on the cat, not the one above the cat?

Meaning, I don't want to take the shield off that is attatched to the car, but do want to take the one off that is attatched to the actual cat.
Is that ok?

I removed those rattly mothers last summer. I am glad they are gone. I still have the shields on the header and the shield between the car and the cat.

Be careful not to start a grass fire.
