this isnt related to this forum, Im moving it.

Also, I dont think you will be happy with it. Too loud and little if any changes in performance. Save the money and do it right.

 

I thing a loud exhaust sounds good, but theres a BIG difference between a nice sounding loud one, and a noisy one. If you just cut the muffler off they sound like shit. The open pipe lets all the good and bad noise out, and the bad noise seems to drown out the good noise.


If you want to do it though, it will free up some air flow, but your not going to see any milage improvement

 

Don't do it. Cutting the pipe of short could lead to exhaust fumes making their way into the cab. If you want to do without a muffler extend the pipe at least.

 

I do intend to extend it out the side to avoid fumes. I have heard other trucks with the pipes cut and they sound great to me, so thats why I was wondering how it sounded on broncos specifically. Basically to put on a nice exhaust system i'm going to need a couple hundred bucks. Unless I find that it will hurt my engine or something, I think i'm probably going to do it. Cut it that is.

Well it figures
When I was 18 I also thought anything that was loud sounded good.
Now I have made exhaust systems with different mufflers and modified mufflers that are louder than no muffler at all and it lets out only the good noise. The bad noise gets quieted down.
The best system I have done yet is on my F150. I dont think I can improve the sound any more than it is. And I wauld say its louder than just an open pipe with the muffler cut off.

 

I found a local shop that sold used mufflers, and he cut out my cats, put in the used flowmaster for about 150... Not as loud as I'd like but still not bad....

 

The CATs muffle more than the muffler does.. My truck wasnt much louder without the muffler..Maybe alittle. It was deeper sounding but nothing to run home and tell mom about.

 

Heck I cut my muffler off and it doesn't sound that bad to me. Only difference I noticed was that a dual exhaust sounds a little deeper than mine does. I think it does run a little better and I haven't noticed exhaust fumes in the cab while driving.

 

Thanks all for the feedback.

 

Mine fell of and i gained a lot of tourqe! I did burn outs like nothing! But I live in the city so I put a flowmaster on and it sounds better, but not as loud.

What??? :rofl: No fawkin way a muffler made that big of a diffrence. :bs

 

Blanco Has been runnig without a muffler for a long time!
& NO

Its not illegal! At least not in Calif. & I doubt texas is any more strict..
the muffler is Designed to MUFFLE sound & thats about it..

I went and got Blanco Smog checked at a test only place with out a muffler & they said thats fine & not an issue..

& mine is not that loud considering I have the factory cats.

Mine's a '90 Whats yours?

I've had people ask me if I was running a Flow master..

& I tell them NOPE!:thumbup

& I did notice an Increase in power right off the Bat when I removed the muffler...
Not alot but enuff to feel it!:thumbup

I'm a conservitive 38 yr old & I love the way it sounds with muffler cut off!
& just have a elbow pointing it out in front of the Pass. side Back tire.

I'm also told its fairly quite because I'm also running factory exhaust Manifolds..
& that if I had Headers it would be much louder..

 

Cam, I had headers on my f-150 (exact same exhaust as whats under my bronco now..I took it off when my wife wrecked it) and now its running on manifolds and I only noticed a sound diffrence and maybe alittle buttometer loss..Nothing to burn tires with though.

 

In Texas the exhaust must extend out behind the back tire or it won't pass inspection. I'm glad to hear some positive things about cutting it, especially from some veterans, because I think I am going to cut it soon.

You are not alloud to run side exhaust in texas?

 

ours has to go past the back seat... but no inspection.

I have a turn-down and I've never had any trouble . . .

Before I spent a lot of money on an exhaust system, I ran a hollow (pipe) $15 glasspack and it wasn't loud at all. No real power or loudness either. Just kinda deep and mellow.

You have 2 cats on your bronco. That will make a difference in the sound. But I think it is a good idea. I build power units, Waukesha Natural Gas engines and we only use a CAT on them and some are in Residential areas. Not a bad idea there white bronco:beer

 

Quack, the 2 cats are stock...the front is a NOX and the rear is HC/CO

Sounds like they need a nice DOT audit

You need a muffler, it also acts as a spark arrester for OHV use.

 

I deleted this dreaded Double post..

Hmmmmmm.........

& yes, I've heard that even some wheeling clubs require it before you can wheel with them..


Well it dont effect the emmissions..

But as far as that link goes.....It just gives me a blank page....?

 

If sparks made it all the way to the back end of a truck..then something needs to be done about the way the truck is running, not the muffler being there or not... (CA IS GAY)
