SOURCE: Exhaust pipe rattles when car idles. Had muffler

Check the heat shield on the Catalytic Converter, after a few years they start to rust off and rattle. Crawl under the Pathfinder and bang along the Converter and muffler area and see where it's coming from.   Good chances are, it's from the heat shield since you already had everything changed from the Cat back.
Good luck and hope this helps.

Your catalytic converters guts have broken apart and are exiting the pipes. It's like a honeycomb lattice structure. Replace catalytic converter.

SOURCE: I have a 1999 ford f150 exhaust pipe and muffler

did the flange come apart or did the pipe break, if the pipe broke then you will have to replace the system fron the flange back, these exhaust systems look good but corrode from the inside out, get a new system i will probably come in three pieces, and new hangers, its pretty straightforward

Last time. I have Ford focus 2003 sedan dohc 2L. I lost a part from exhaust system. from back to front I see 1. tail pipe 2. rectangular box shaped part? Lunch Box? 3. missing part Muffler?


Starting from the front, coming off the exhaust manifold should have, 1. Exhaust pipe, 2. Catalytic converter, 3. Exhaust pipe, 4. Resonator, 5. Tail pipe. Also, there should be an Oxygen sensor somewhere around the catalytic converter.

DIY Replace Back Muffler / Resonator with Straight PipeSubject: DIY Replace Back...


DIY Replace Back Muffler / Resonator with Straight PipeSubject: DIY Replace Back Muffler / Resonator with Straight Pipe
Title: Increase Fuel MPG by Replacing Back Muffler

Overview:
When your back muffler fails, and or if you want a bit more gas milage, replacing the back muffler with a straight pipe seems to work fine and increase MPG. This is much cheaper than purchasing a back muffler with DIY or to have a local customer shop install a straight pipe.

Symptoms:
Back muffler failing, onion peeling and / or holes in the back muffler.

Experience Level:
Medium

Tools Needed:
Hack Saw, Ratchets, Wrenches, etc.

Time Needed:
About 1 hour:

Parts Needed:
Pipe parts from local auto store. Exhaust sealers, hangers, pipe tip (stainless)

Procedure:
Remove the back muffler by cutting the pipe before the muffler about 2 inches in front of the muffler. Replace with straight pipe components or have a shop do it. You will need some time to get it 100% right. It took me a couple of tries.

Outcome:
- Money savings in replacement.
- Slightly louder, but not much. Actually a better sound (subjective)
- 1-5 MPG gas savings, especially on open road.

Discussion:
I have done this on a 99 9-5 I4 for about 1 year now and it seems to be working fine. I am getting about 3+ MPG on the open road since this was done. It is an automatic with 140k miles solid 29-30 MPG with regular fuel on the open road. I really do not see the need for the back muffler / resonator at the present time.

I will be doing this on a 2001 V6 wagon soon. The muffler will be failing soon.

Any decent muffler shop will be able to help you. Remember its an 84 so its likely a muffler shop will have seen this before

Is it important what size muffler and resonator, is replaced on a 2001 chrysler town and country V-6 engine? Sadly, I took my van to have a new muffler put on it. When the mechanic, called he also said...


Possible results are , increased fuel use, reduction in power and you may fail noise emissions (too much noise), some after market exhaust systems are designed to give improvements but these are general much more costly than standard fittings. I would not be happy myself and would want it put right, Not sure which country you are in so can't advise on trading standards, but in uk items must be fit for purpose or you get your money back.

2003 Chrysler Town and Country Exhaust does it make a difference if the muffler is first and then the resonator last? that is what Midas did to my van and its louder now with the new exhaust


Yes, the muffler should be upstream of the resonator. In other words, from the engine, you have the catalytic converter, then the muffler, then the resonator is last, near the tail pipe. Possibly they installed the wrong muffler or resonator. The muffler will have the most effect on the sound you hear.

What is the right exhaust to use for a high compression setup on an h22a?


for exhaust, if you want stock looking then get a prelude muffler and have a shop make the piping the same size as the prelude exhaust (which is 2.25 i think?)
if you want sleeper exhausts then
get two 2-1/2" dynomax race bullets $27.95 ea. from summit. and a Magnaflow street muffler in your style of choice. $120?? get 1 race bullet welded in just behind the cat or header and the other back before the first 90 degree bend and the muffler welded on.

This is the best way to make a super sleeper. Magnaflow's are super quiet.

Race bullets act as resonators. they are only available in 2.5" in/out but thats ok.

Cant find o2 sensor looking for upstream bank 1 any one want to help?


It should be located near the outlet in the rear exhaust manifold, ahead of the converter. The downstream sensor 2 is the one located behind the converter or sometimes in the rear of the converter body.

Exhaust


Good Day,

Most aftermarket exhaust systems are cat-back. You defiantly need to keep the cat to comply with local emsisions regualtions. However you can remove the mufflers and replace them with high flow mufflers or resonators. Try to replace them with something not too loud so you are in accordance with noise laws in your area. I have a 2000 s10 with no mufflers, just a cat then a y-pipe to make it dual with two resonators coming straight out the back, I live in the states and made sure this sytem was 50 state street legal before I purchased it. I suggest you do the same to avoid harrasment by the police.

Good Luck

Hope this helps.
