Flowmaster Muffler Rattle

[TwentyPints]

got it checked out when i got an oil change...they said it was a rattle from inside the muffler. its been on about a yr, doesnt rattle all the time...it comes and goes. could one of the baffles inside the muffler be loose? anyone else had this problem, do i need a new muffler already? thanks, jeff.

I had another brand do that to me on my 442. The baffles came loose and rattled intermittently. Try banging on the muffler with a rubber mallet to verify.

As a temporary fix to mine, I wacked it good in the center with the round end of a ball peen hammer. Rattle came back after awhile though so I replaced it.

had a muffler start rattling on my old camaro and i took a hammer and beat the shit out of it and it quit, but didnt look the best.

Welcome to the club. I bought my truck used with 41K and it had a 50 series flushmaster single in dual out with 3" chrome cannons. By 47K the cannons were rusted completely over and the muffler was rattling bad, I said BAD. You get what you pay for and stainless is the answer.....

so if a baffle is loose inside...basicallly the only fix is to replace the muffler? maybe a magnaflow this time? what about cuttin off the muffler and havin just straight pipe? ...guess that would be way too loud.

ive heard a truck with no muffler , it is very loud and has alot of popping when letting off after accelleration

whats a better muffler to get that will last longer than a yr that wont rattle and isnt a big peice of shit? magnaflow?

I thought Flowmasters had a lifetime warranty. I know with Midas where I had my exhaust installed they told me it had a lifetime warranty.

What ever you do get SS, thats Stainless Steel.... Chrome will always rust no matter what you do and how often.... Good luck searching

I dont think you should go with magnaflow although they may be a good muffler the sound they produce is horible i think you should go with another flowmaster and if you dont want to a muffler that is very simular to flowmaster is vortech i belive thats how you spell it just search vortech exhaust and it should come up the the exact same muffler as flomaster just a different name but create that awesome sound that you want

i will have to look into the warranty for my flowmaster...i thought it was limited, and the magnaflows were lifetime...i could be wrong.

Get a Borla muffler to replace yours. They sound very good to me.

My Flowmaster has a rust hole in it, and its 3 years old. I'm replacing it with something that wont be as loud when I remove my cats.

[TwentyPints]

ive heard borla is pretty good... what about gibson? do either make anything in stainless?

i love my magnaflow...i got stainless steel too...i dont think ill ever use a different brand on a truck again...
