Hi all,

I'm new to this site, and as the title suggests, I'm having car issues. When I let go of the gas, I hear quiet "pop, pop" noises coming from the rear, and I'm assuming it's coming from the exhaust.

Also, I've noticed that the muffler sounds lower and a tad louder than normal, but when I stand outside to listen to the car being driven around, it sounds relatively normal.

Does anybody have any ideas or information regarding what might be happening? I'm a bit tight on cash so I don't want to take it to the mechanic quite yet although it seems like the best option to.

Thanks in advance!

^ your exhaust tries to break somewhere

so to the muffler shop definetly if you cannot do some welding yourself
sounds like theres a hole somewhere or maybe some flanges welds are going to detach

when my old accords exhaust started to sound lower, one day soon after that my back muffler fell down on traffic lights

you can try to check whats going on there yourself by going under your car with flashlight

thanks

When I was 16, I had a 90 Prelude and one day the muffler went really loud but I never figured out what happened. It died not too long after.

Now this is a 91 Prelude, and I'm just afraid the car is getting close to it's expiration date with the louder muffler issue. I love it to pieces though. If it's the exhaust/muffler, do you know approximately how pricey the fix would be?

^under 200 if its just the muffler and maybe some piping at a local muffler shop

under $55.00 shipped I got this muffler on eBay for my 5th gen car to replace the raspy Ghetto Can that it came with. Item #360382376577 the seller was awesome, shipped it out quickly, and it was MUCH better quality than I expected. Everything lined up perfectly. Use the item # to look at the seller and do a search... or just do a search period.

Usually the low sound that you are talking about is a leak in the exhaust somewhere causing your pipe to become a large, low sounding wind instrument.
The popping is usually a sign of too much fuel entering the cylinder and igniting(leaking injector or bad spray pattern generally) or a bad timing issue causing the fuel to not ignite at the right time. If your exhaust leak is before the o2 sensor, it is possible that the ECU is deciphering that it needs to make the fuel mixture more rich. Find your exhaust problem, and if that doesn't fix things, check the injectors and timing.

Tell-tale sign when searching for a crack or leak is look for black carbon build up. You can take a moist hand towel and wrap it around the area to test, and if the sound goes away, you've found your leak!

Mine is doing this at the moment due to the flex pipe having a fairly large crack. New header and downpipe arriving on the 24th... Can't wait!!! then I can finish working on the tuning.

Do not let that 91 die!!! if there is a possibility of a timing issue..check and find out immediately because if that belt goes, you either will need a new engine, or to do strenuous head work. But idk, the pros know what theyre talking about.. Im just feeding off them. But change that belt anyway if you dont know the last time it was changed.
