hey everyone. after leaving my forester for 4 weeks without driving apparently one of my mufflers stopped working. the other side is fine. could it be some dirts got into the muffler and dried? was working fine before.
That was my question as well.. If it's that there is no apparent exhaust coming out of it, it may well be blocked.
That would take a lot of dirt. Were you wading the car through a mud bog? Otherwise unlikely.
Rodents on the other hand could have built condos in your exhaust system in less time.
Since the dual exhaust is actually a single exhaust with two outlets, it won't take much blockage for the exhaust to take the easy open path.
thanks everyone. what chemical should i use to clean the interior of that particular muffler? i dont see anything blocking tha main passage when i see it from behind. will take it out and try to clean it when i get some spare time.
You have a manifold on each head, since the car runs you can rule them out as an issue. Your problem must be after where they meet under the car. Trace that pipe from the muffler forward. On my 2010 that's a very short section.
@2.5x_sleeper thanks for your input. mine is japanese model . 3rd generation japanese models started in 2008 until 2013. so mine is 2008 model SH5 2.0L engine thanks again everyone i will have a look at it today and see what the story is.
ok guys just finished checking and one of the 2 pipe lines that goes seperate ways from the main pipe is not blowing. tried blocking the working(left side) pipe and brought RPM high but didnt fix the issue. have to disassemble the rear pipe and see when i get a chance. by the way what is inside the chamber in the middle?
