Home made muffler silencer.. ideas?
Tuesday, October 21, 2008 12:39 PM
i just put in my 2.4 two huge fart cans, and they are really loud in the winter during start up,
i cant be waking people at my house at 4:30am or my cars going to get keyed lol

prices for silencers are about 30 bucks at Canadian tire and 60 at mufflerman.

they dont fit my mufflers exactly tho there a bit small, but still might work.

i was wonder is there a way to quiet mine down just so i can get off my street.. ex, sticking a sock in one or both... or silencer in one and sock in the other and pulling the sock out around the corner

i just dont feel like spending 100 bucks to drive down my street.

any advice? thanks guys!

Umm... ditch the "fart cans" and put something quieter on there?

Please tell me you didn't see this coming, did you? I mean... seriously... they're big melon cannons... didn't strike you that they might be outrageously noisy?? I mean, they are on every other car out there...

Ok fart cans is the wrong words to use. there worth 120 a piece there not junk
there low resistance, there just overly loud on a cold morning, once there running they sound great

straight through round body muffler that needs a silencer? yeah, its junk. sorry, you overpaid. you may have PAID $120 each, but thats NOT what they're WORTH. get a real muffler. no, really. dont even bother trying to make a silencer yourself. what i dont get however, is how you thought to yourself when ordering these grapefruit launchers: "they wont be loud when i go to work every morning. this has GOT to be a good idea."

steel wool and a nail. Drill a hole in the tip, slide some steel wool in there and slip the nail through it to keep it in there! should be a little quieter!!!

first off, round body mufflers are a disaster...I know, been there and done that. Use oval body mufflers and use a RESONATOR bigger than 18" long....

Those mufflers you currently have are poorly designed, cheaply made pieces that are meant to appeal to the fools who latch-onto the latest trends & want their car to look "cool".

Your best bet is to fully start over & design a system like many others here have. One that uses a resonator or glasspack muffler mid-ships in the extention tube between the catalytic-convertor & the first turn in the pipe after it before the axle, and a good quality "Turbo" muffler of reasonable size (About the same as the rest of the system) that has a flow-rating in the size you choose that's 2.2cfm@10.5"hg drop for each HP the engine produces (Be realistic in estimating how much HP your engine produces!).

Search around here for exhaust threads & you should see posts & pics of what others have done to help you. The best part of having a system like I described is you still get a nice, deep tone while maintaining a low, street-legal noise level. And your neighbors will thank you for it!

This is has alot in common (In principle) with using a muffler that has a larger I/O-diameter than what's desired in pipe size, just to have a muffler that meets the flow-levels desired, while still maintaining proper pipe size in & out of it. And using a larger case muffler at that.

The increased chamber area would further reduce exhaust noise, while using reducers (Found at any commercial truck supply store) to match the I/Os of the muffler to the size pipe (If it's smaller) used to match the engine's HP output that has a flow-rating of 2.2cfm@10.5"hg for every 1hp.

you must have thought those crap cannons were going to do something other than sound like 1000 bees shoved into a soda can and kicked around till super uber pissed off. well you were wrong. want something that sounds good, get at least a 2 foot resonator and a flowmaster super 44, then itll sound good. im mean sure i sound like a 1500cc rotary engine airplane after 3 grand and a semi before that, but thats what makes the v8s in my area pee their man panties. but i have 2 1/2 in from the header back with no cat and a glasspack on the end, you dont know loud till ive flown past your ass.

If the guy wants big dual rice cannon exhaust thats his own problem, but he was looking for ways to quiet it.

Ebay = muffler silencers $9 shipped each.

ok i have some good ideas now...

i dont have the two mufflers in yet but i do have in a dynamax oval muffler in just on the one side,

any opinions on what would sound better?

dynamax muffler with no resanatorx / with resanator / with cat and resanator?

would it sound good if i put round body mufflers then a 2 foot resanator?

thanks

muffler and resonator are your best bets for sound...resonator will give it a deeper tone with less rasp...and will quiet it down so that you car doesn't drone away on the highway...I would say get atleast an 18" long resonator. You should always have a cat, it helps to reduce unwanted noise and saves the environment all at the same time. It can also keep the law off your back, depending on where you live.

Magnaflow makes good cats so yes you could buy one from Crappy Tire...might be easier to order it online and possibily cheaper. As for them doing a lot...it depends on your mods. I see you don't have many, so I wouldn't say its necessary, unless you plan to mod a lot more. The only reason a "highflow" cat is better is because its internal piipe size will match your custom pipe size (preferably 2.25") which then means there is no bottleneck effect at the cat. If you aren't changing your pipes to something bigger then I wouldn't say to even bother...unless you are doing a header back exhaust, then a cat with a bigger inside pipe diameter would be warranted.

this is for a homade cheap muffler for temporary use find an old small air tank blow holes in it to fit one pipe in and one pipe out the pipes are parallel on the inside you drill or blow torch out baffle holes on the part of the pipe thats going to be on the inside of the old air tank or any metal canister that is seal or that you can weld shut.... done this before it canbe fun not mention you might come up with something you know?
