Rattling Sound
 

Ok when i first crank my truck and start movin it makes a rattling sound almost directly under my feet ...... also when im goin down the road and get in it and it downshifts it does it until i let out of it .... its hard to describe the sound i wish i cud a video .... it gets on my nerves so bad! I thought it might have been a loose heat sheild but i checked them all and there tight .... could it be the cat? but its not under my feet its more like under the backseat floorboard .

HELP!

Has your exhaust tone changed? Has the smell changed? Crawl under it and tap it with a small hammer and listen for rattles. My 96 gas burner did the same thing when the cat broke loose inside the canister. Luckily, dodge fixed it under the emissions warranty. Otherwise, it would've been gone...

Smell and sound hasnt changed since i bought it few months ago , heres a video , u can hear the cat kinda rattle , it gets better at the end

Is the exhaust rubbing on anything? I know on mine it cut pretty close to some stuff before I put the 4 in on. Bunt mines a little different.

no its not rubbing anything , its clear of everything ....... Abe is wantin to do a cat and muffler delete with a straight 3" pipe on it . what yall think?

just found this

Long tube headers, true duals, flowmaster super 40's, and turn downs in front of the axle...

I didnt win the 640 million last nite :jester:

i dont have alot of money to dump in it right now

I didn't either, otherwise, id be on my way to Utah to Industrial Injection...:favorites37:

i seen i guess it was your wife downtown in your truck other day

looks like a tube of silicon might be your cure.

I checkd the midplate but it doesnt have any movement

The Y pipe then like the first link?

Car delete with straight pipe gets annoying on a v10.. At least it did on my excursion. I ended up with cat delete, single in dual out flowmaster 40 series with dual tailpipes exiting out bumper corners. Sounded much better to me!

Y pipe isnt close to anything B

06 - i kno on my f150s with cat delete the exhaust smelt terrible like a old ass 70 model truck , did your v10 stink?

Might have been. She uses it with the tree service sometimes...

Wat tree co is it bud

Im stumped... guess youll find out if you pull those cats off.

It aint got but 1 , i just dont want it to stink , new cats are highhhhhh

No, mine never did really. I hate noises I cant find!

U do kno wat stink im tlkn bout rite? Lol

Exactly! you smelling what i'm thinking??? Lol!

Collins tree service in south Jackson.

Ok 06 u said it wont stink so if it does ima kick yer ass lol

Trevor - got ya

I bet that cat is fried and busted lose. You can take the cat off then gut it amd put it back on. Or take it off. I would.

The cat will come off if i kno it wont stink

scrap yard cat?

Junkyard?
