Straight pipe, no muffler?

[DR3W]

Im wondering how a straight pipe would sound. My engine sounds almost like an electric hybrid or something! I wana remove my stock exhuast, but dont have the money for a new one that i want right now (flowmaster 40 probably). But if i remove the stock muffler right after the cats and just run straight pipe to the tip, does anybody know how this will sound or have done it? Just thinking about it Thanks

look it up on youtube. There are a few videos of the first gen with straight pipe and they don't sound to bad.

i have my V10 excursion straight piped and i LOVE it. i've been debating on doing to my expedition also but i think i want it alittle more mellow as to not piss off all the houses around me lol i'm sure on a V8 it would sound down right mean...the V10 has a very different but i think great sound.

Here is a video of mine. I have the stock 4 cats on with a Y and dual 2 1/4 inch pipes with 3 1/2 inch tips that exit at 45s from each corner. It has a great idle, and really loud and throaty when you get on it, and as long as you are listening to some tunes while driving down the highway, you'll never hear it.

im running rear cat delete with a glass pack and single exit for now will be dualed someday....

the glass pack gets rid of the crackle but doesn't cut down on the sound

dr3w you're in cali you cant legally do it. but if your next smog test isn't for awhile you can try until its time for test then you have to put one on. but be careful the cops can ticket you for it. especially since it will be a lot louder than stock.

Oh yeah, was wondering about that. Thanks alot. Just gunna save up for a flowmaster, thanks guys

straight pipe is loud and sounds sick... I would do it but need it too be a little more mellow.. so the flowmaster 40s and true duals are the way I went.....also rear cat delete... glad I am not in Cali...lol

okay heres how cali laws work. some parts of cali dont have smog! like ramona and julian. so yeah! haha but most parts of cali do have smog. or is it that they dont have to have a smog on a dyno... who knows. either way smog laws is by city, but most by state. of just give the guy a $20 and youll be good. ahah

Same here! I think there would be more than a few very angry people if that were the case in Wyoming.

every other truck in NNY has straight pipes... my old 97 f150 did... but I like the mellower flowmasters.... guess because I am older and have a kid its nicer.... plus a little quieter when going by the PO-PO....lol

I cut my muffler off and dumped it. I like it but I really want to run it to the back or do side exit in front of the tires on both sides. Not sure it would work on the driver side though.

 

[walnuts4x4]

my true duals dump behind the pass rear tire almost looking stock.... but one day I am gonna change it to dump on each corner just outside of my trailer hitch....... on my old 97 f150 I had cut off the muffer and welded a 3" pipe that dumped right in front of the pass tire and had an angle cut... that was freaking loud and cool but dont want it that loud now a days,,,lol,.... never thought I would say that but I guess it happens when you have a kid...lol

I have kids the louder the better it helps them go to sleep on those road trips lol

 

[DR3W]

I want straight pipes but CA laws make it illegal, gunna get the flowmaster 40 series instead. haha

Cut muffler-
click pic for vid


It now has a turn down and muffles the sound some but not much.

 

[walnuts4x4]

sounds good.... I am thinking of removing my 40s next time my exhaust has to be redone... pipes only last 2-3 years with all the salt NY uses

Thinking about doing a true straight pipe. I suspect clogged cats. Not paying an arm and a **** to replace them. My mustang had cats removed plus a flow master 40 and sounded amazing. Hoping to get the 5.4 to sound similar.

I cut mine off after the cat on my 5.4 and it sounded MEAN. Window shaking, alarm setting off MEAN. If that gives you any inclination of how yours would sound, do it. **** a muffler.
