Since there so many exhaust questions floating around, why not have them all in one spot. heres what i propose, everyone who has a soundclip(s) post them here. also post a small description of what they are running and any mods done to the engine.

please try to keep any questions/chit chat out of the thread, this is for soundclips only, this way it doesnt get cluttered up. also could a mod please sticky this? since its one of the most asked questions here.

 

I posted this in the exhuast forum but figured i would get a lot of replies here too.

alright, i have been doing a lot of research and talking to people and i want to sum up everything i think i have come to. please throw in any and all suggestions.

i have a brand new 300 straight six in a 93 f250. fuel injected. it has been bored 10-30 over (reman engine). somehow i got ahold of a carbed head. i have efi exhaust manifolds. i want to cut off both cats, y the two manifolds into a 2.5 inch pipe. as close as i can to the y, i want to put a magnaflow muffler si/so and run it out before the passenger tire. if it sounds a little raspy, i think i will buy a 2.5 in universal cat and stick it on there right before the muffler.

what are your opinion? did i compile all of the information pretty well? i know this has been beat to death but i wanted to be sure of my setup before i spend a bit of money. thanks everyone for all your help!

I know this isn't a sound clip, more of a question...perhaps this post would generate a bit more responses if it were a combination of ?'s and sound clips. i like where you are headed with this though. i agree, should be turned into a sticky.

i would run one cat anyway, they dont hinder flow to much like the older ones do. it shouldnt sound to bad, close to what i run now.

PS: soundclips please

 

can i just buy a universal 2.5 in/out cat off of ebay? i don't mind at all using a cat, i just wanted to pop this old one off because i feel it may be bad and perhaps even partially clogged up.

as soon as i get it done, i will post the clip...it may be a little while because i am also working on the body right no.

u sure can! i bought a univeral magnaflow cat at a truck show for $40.

 

i removed my air injection on ole blue, which was put there to keep the cat from overheating, correct? if i install a cheap highflow cat, will i have to worry about it overheating without the air injection?
chris

 

the air injection is there to help burn off and excessive fuel. i have mine removed and no ill effects, and its has been almost 2 years since i did.

i reckon u'll be fine, as long as the engine is in good tune.

 

alrighty...after quite a bit of work, i figured out the system that i like the most.

originally, i was going to y the two manifolds together on my 93 f-250 (fi). i was then going to run 2.5 exhaust into a highflow cat and then into a magnaflow muffler.

i took it to my exhaust guy to y the two together...all the parts and labor only cost me $25 even. after the y, i temporarily ran the 2.5 inch straight out. while i liked that quite a bit, i thought it was a bit too loud...i just didn't want to get pulled over. also, it was a little loud in the cab (i couldn't really talk to my girlfriend on the phone).

i had a 2.25" magnaflow muffler laying around. though i know it was not the right size, i held it up tightly to the y and had my brother rev it up a bit. this seemed a bit too quite for me, while it still sounded good.

my next step was to put on a small glasspack or get a highflow cat to help take some of the harshness out and maybe quite it a bit. instead, while i was on a cruize, my brother took it all apart and built a glasspack/silencer. he put it all back together. when i got home, i was surprised by a nice sounding exhaust. i took it all off (at the time, a lot of it was clamped together) and welded everything up nice and tightly. i put it back up and laid down a bead of weld to finish it all off. i really like the sound of it. wide open, sounds awsome. if i just rev it in park, it just sounds ok. today i am going to be outside doing a bunch of work, as usual. i will try to take some vid's with sound so you all can get a good taste of what a homemade glasspack sounds like on a straight 6. i will also try to draw up an idea of how to make a glasspack, for those of you who are curious. thanks for all the help with the exhaust everyone...it has been a long process.

i have the efi manifolds with 30 inch glasspacks i love its got a nice low rumble sounds great to me.....

 

alrighty...sorry again about the delay. i have some videos with sound. how do i add them so you all can check it out? is there somewhere i need to upload them and just give you a link? thanks.
chris

 

okeydokey...FINALLY. i kept getting busy but i got it all uploaded today. remember, ole' blue is still under construction...

again, what i have is a 93 f-250 rebuilt inline 6, bored to about .03. it is fuel injected with the efi manifolds. both manifolds are y'ed together into a 2.5" pipe. as close to that y is a homemade glasspack. 2.5" the rest of the way, dumping before the rear end.

one video was an accidental video i think but it gives you a good idea of what the truck sounds like at a normal driving speed and idle. you also get a decent look at my younger brother's car and our blue f-350 diesel in the background.

i hope you can get some good ideas of what it sounds like. there are some background noises that tend to interfere. if you want me to re-record something or would like a recording of me driving it in some other way, let me know.

let me know what you think.

thanks.

i guess you need the site, don't you?

not to shabby, im gunna have to switch to photobucket for my sound clips...those were easy and quick to load.

 

4.9Inline6- just wondering, about at how many rpms were you shifting in the clips that were shot from inside the truck? also, how high were you revving it in the clip titled "rev"?
thanks

 

ummm....i have an auto tranny that shifts at no higher than 3,200 rpm. the rev....i am not positive but i would guess 2,000 - 2,500.
