Heat problem with my left side muffler

Question From cubeus19 on Heat problem with my left side muffler

Hello everyone. The car I'm having problems with is a 2003 Pontiac Sunfire.

It has dual exhaust pipes as well as mufflers. And last night as I was unloading things out of the trunk my hand touched the floor or carpet area of the trunk and it felt pretty warm.

So I lifted the cover off that leads to my spare tire where it is bare painted metal all around and it felt very very hot.

So after I waited awhile for the car to cool down I felt around the exhaust system and everything felt cool except the left side muffler.

Now some things I did do to the car right before I noticed this problem and I'm wondering if they could have caused it.

The first thing I did about three days ago was I went over the exhaust pipes, muffler and so on with some steel wool and some metal polish to help remove some rust.

That and I also added some fuel system cleaner to my gas tank right before I filled up to clean out any gunk that might have collected over the winter because I didn't do alot of driving during the winter.

So do any of you all think any of those things could have caused the problem with the left side muffler getting too hot?

If so what do you think it could be? Anything I can do to unclog it if it's unclogged?

It don't appear to be since when I run the car I felt just past the left side exhaust pipe and I could feel air blowing out of it.

Any help with this will be greatly appreciated. Thank you for your time.

Is this an OE design or custom work? Dual everything including converters?

Yes it is OE design.

Response From Tom Greenleaf

Enlighten me as I can't find anything dual for this car that is "Original Equipment" for exhaust?

Just a muffler (one) with a split tail pipe attached like this if it shows.......

Unless custom work then what? If a 4 cyl had true duals they still should share some sort of "H" pipe which balances both back pressure and cancels funny sounding exhaust.

If custom then you have to explain if two converters or one with two outlets or what. Heat picking on one side doesn't make sense to me yet and if the body and parts are not properly heat shielded it could be a problem to outright dangerous?

You have to upload them to a hosting site like Photobucket or Image shack and they supply an image link.

Response From cubeus19

Let's see as far as I know it's not a custom job. Is there a way I can post pictures here? If so I'll post a couple of photos of the back of the car and that might help.

Response From Hammer Time

I don't know what you are driving there because the picture I posted is the only one listed in the exhaust parts catalog for that year and model.

Response From Hammer Time

Yes, I'm aware of that but it doesn't match up with the system that car was made with.

Response From cubeus19

In my original post I thought I said what year and model my car was. It's a 2003 Pontiac Sunfire.

Response From Discretesignals

That vehicle does come with dual exhaust as an factory option. Probably on the GT models. Guess the aftermarket doesn't show it. There is a heat shield that is supposed to be riveted above the muffler on the right side.

Response From Hammer Time

Good find. Here's just the image

Response From cubeus19

Let's see as far as I know right now, I'm starting to think I may need a new heat shield around my left side muffler and possibly get one added on the right side as well. But I was wondering how do you put one on? Is that something I can do myself? If not how much does it usually cost to get one put on? Thanks.

Response From Tom Greenleaf

This is becoming a mind warp. Pic on post #14 and part layout of Post #24 show NO heat shield on this set up for that muffler and by pic on post #14 if even a generic heat shield (available from Walker or Maremont) that I've had in my hands wouldn't fit without rattling against that spare tire well anyway.

Note - This isn't dual exhaust but rather dual mufflers. IMO and not surprised if this was engineered by GM I hope that engineer isn't working for GM anymore!

About every car maker has made mistakes and I think this is one of them. Perhaps a high end custom exhaust place could find or make up something to shield the heat??

The RPO code is N10 for dual exhaust on that year. I have a dealer IPB of it but can't figure out how to extract it from flash.

Response From Hammer Time

The only engine available for that car in that year was the 2.2 so I really doubt they had a GT option for it.

Response From Hammer Time

That may be the RPO code for dual exhaust but that doesn't mean it was an option on that vehicle. I don't see a 2.2 with dual exhaust and Walker sells no replacement part for one.

Response From cubeus19

Hmm, interesting, it may be some type of special/custom car and the dealer that sold it to me forgot to mention it.

Response From Discretesignals

The left side muffler doesn't have a heat shield. It's close enough to the floor board to transfer heat off into the trunk.


Response From cubeus19 Top Rated Answer

A correction on that, that picture if towards the right side of my car, and that is the right side muffler.

I just looked on the left side and I think I do have some type of heat shield over it.

I may no longer work like it needs to. Here is the photo of my left side muffler.

Response From cubeus19

If I'm allowed to post links, here is one I found while doing a image search. Mine looks something close to what this one does.

4 cylinder? dual exhaust? not hardly.

Response From Tom Greenleaf

Hitting at same time as we do HT. I couldn't find anything but a 4 cyl and only exhaust difference was California for a single converter,

Response From Hammer Time

I just looked at the system. Single pipe all the back to that muffler.

Response From Hammer Time

You can't have a dual system with only one head to start from.

Question From mattmro444 on car not starting

I bought a 2004 MG ZR 1.4 petrol with only 36,000 miles on it back in January and despite identifying a few problems with it (last time I buy from that dealer) it's been running fine. Then one day I went to start it and nothing, wouldn't even turn over. Figured it was the battery, bought a new one and discovered my lights were on. Why I couldn't tell you since last time I used it was in the middle of a very sunny day, I guess I must have knocked it by accident? Whatever, I thought that would be it sorted, except I still can't get the thing to start. It at least turns over and sometimes even runs for 1-5 seconds, I even got a couple of revs out of it once but then it just cuts out again.

Things I know to be wrong with it that might give clues. Head gasket is going, I was going through a lot of coolant (there's enough in it right now) and I tried to use some K-Seal hoping it was just a leak that could be plugged as that worked on my old car. I noticed checking it today there is a milky white layer on top of the coolant which I believe is further indication of head gasket problem, but that shouldn't stop the car from starting right?

Part of the exhaust needs replaced as it has been spitting out the muffler material for a while now. Could that have simply just completely blocked the exhaust preventing it from starting?

I'm pretty sure there is some kind of electrical problem with the car too. There have been occasions, almost always when the car has been running for a bit and then turned off (like when I drive to the shop for example and get back in with my groceries), where it won't start. I turn the key, nothing happens. After fiddling with it for a min it will eventually start. Also had a lot of problems with my alarm (it's just the standard fitted one i believe) in that it would keep going off. I had to take the fuse out when I was trying to get it going again otherwise it was going to make me deaf. Someone told me they had a problem like this before and it was due to the alarm, but the car doesn't have an immobiliser as far as I know so it shouldn't prevent it from starting?

If it wasn't obvious I don't know a whole lot about cars, but I am generally pretty good at fixing things and following instructions so i'm hoping it's not something too serious/complex to fix. Any suggestions?

Response From Tom Greenleaf Top Rated Answer

This not sold where most regulars are but just the same. You have basic symptoms of bad battery cable connections and you said you knew head gasket was leaking AND ADDING SEALER JUST MADE THAT MORE OF A PROBLEM trust me and now just clogs radiator and heater core. Despite claims sealers don't seal head gaskets and should be avoided in general.


Exhaust full of debris could cause excessive back pressure but would crank so that wasn't it then. If so usually loss of power first and guess if muffler if throwing debris is just clearing itself and probably not a restriction but needs to be fixed too.


Lots more could be wrong with a known head gasket and milky coolant also check oil or could ruin this engine beyond fixing the head gasket?
