yea dude i seriously had to yell even with the windows up when i was startin off!!!

 

Holy Shat!!
I know what that is like

f150fella08 Whats your setup?

Plus I was wondering I have a bad rattle coming from under from truck sounds like my cats are about to rattle off!

Do you think they are bad?
Will that be a reason for me to be able to rplace my cats with maggies??

 

redrider150 here you go...the rattle might be a broken hanger and your pipes are just hitting the frame and there shouldnt be a reason to get hi flow maggie cats JUST GET 'EM

as for my set up...2 maggie hi flow cats, part number 94106, tru dual flowmaster 10 series, H pipe (makes it idle a little queiter and evens the exhaust flow into both mufflers) ran back 45'd into 3.5"x18" tips my exhaust clip is my signature if you havent checked it out already

 

and if you were wondering my set up before (the one me and darren were talkin about yelling at the passenger) it was that same set up just with no cats...i have a video in my youtube profile of that one as well go check out all 3 vids!!!

 

Wow man your new system does sound good.

And for the sounds it doesnt sounds like a broken hanger because I had a broken one before and it sounds way different.

My dad had the same problem on his avalanche it was like a metallic buzzing sound and when he got it checked they said his cats were bad.

Oh well I'm getting High Flows Anyways

 

Dude!! that 11sec vid on your youtube profile that sounds so mean!!!!

Was that the setup with no cats????

Did you have any mufflers or the H-pipe?

 

yea man that was no cats 10 series flowmasters and the H pipe...i poured some seafoam down her and she started loping like a cam so i recorded it haha

 

yea go ahead and cut all 4 off and just get 2 hi flows and thanks for the complement alot of people like it and yea the cats could be bad idk why they rattle or what ever they do but i guess its something inside...my buddy had a built 454 cammed and tru dual 50 series flowmasters and it rattled but it didnt have cats lol

 

Oh haha that would be badass if that was cammed like that!!!

Btw what is seafoam please refresh my memory!

 

yea dude i know!!! i want it cammed so bad!
and seafoam is just an injector cleaner...suck it through the brake booster line and let it sit for 5 or 10 minutes crank it up and itll smoke like crazy! meaning its cleaning all that carbon outta there...and pour the rest in your tank so itll clean the fuel lines out

 

Oh ok thats badass how it makes it sound!! too bad it didnt stay like that for a while!!

Also when adding sea foam after the carbon has been cleaned out can you notice a difference after driving it?

Btw do you know how much it would run to get it cammed???

 

Now thats the spirit

 

Well I'm a certified Ford Tech, have done work in Nascar, work on a drag team, and do high performance modular engines. My truck is old, and has lots of mods from over the years, but I can tell you that high flows are a waste, period. But take it as you desire, my two precats haven't set the CEL, it still passes emissions, and I made money by cutting them off, and can say that the factory precats will flow equally well as high flows, if not better due to their shorter body and less catalyst. But if everyone still has to have those high flows, go ahead don't let that $160 burn a hole in your pocket.

 

yea it cleans out the carbon and and injectors...and yea if its really dirty then yea youll notice a difference...as far as the cost of gettin it cammed...i dont have the slightest idea dude i was thinkin about 300 for the cam itself..then idk what else you would need for it...maybe lifters idk then get some one to do it..

 

It would probably cost an arm and a leg just to get it installed!!!
