Removed the muffler off my ex?

[dirtdigger19]

Today i reemoved the muffler off my ex and drove it around i kinda like the loudness. But besides the tickets i might get is it bad to do this as far and messing up my truck?

 

[storlied]

Nope. Well... depends on where exactly you have the exhaust coming out..

 

[Limited02]

If it's where the muffler was, no. It'll be fun for now, but I bet you will be getting a new muffler before long Or at least reconnect a pipe in place of the muffler.

Do you have the 4.0?

 

[dirtdigger19]

yes i have a 4.0

So hows that acceleration?

Removing the muffler often decreases torque which kills acceleration.

 

[dirtdigger19]

Nope if anything i feels like i pick up faster. But if i get a pipe put on in place of the muffler will it quiet it a little?

I think that maybe be a mind-set resulting from the loudness. Most will agree that removing the muffler kills torque. What we often witness is that the transmission down-shifts around town and on the highway more than it should in order to produce more torque (via higher RPMs and increased gear ratio).

 

[dirtdigger19]

yeah it may be just the noise. But will the pipe welded on reduce the sound?

 

[IZwack]

A pipe welded on will slightly reduce the "noise" because the added length of pipe/tube will absorb more energy on its walls before the gas exits out and into the atmosphere. But it wont reduce it as much as a muffler.

 

[MillerTimeX17]

Wont you loose low-end torque due to loss of back pressure?

 

[storlied]

I have a suggestion for the original poster, why not get a muffler you like? I can understand you like the loudness of the exhaust (I do too).. but there are some pretty cool mufflers out there that can 'tune' that noise.. even making it sound more aggressive... you should check around and I'm sure you won't be dissapointed. Not all mufflers are as quiet as your stock one... in fact.. the stock one amazes me at how much quieter it makes these trucks.. its crazy... checkout some of the flowmaster exhausts on youtube.

California doesn't look too kindly on running vehicles without mufflers. The cops out there are very sensitive to this, because it's so easy to write tickets due to their strict emissions standards. I'd say if you were somewhere in the midwest or the south...you may actually get away with it. But cops in CA don't really put up with it.

So with that in mind (since you already acknowledged that you likely will get tickets)....why not spend the money that you will pay for that first ticket, and go buy a muffler that will still give you the sound that you want, but will also add some performance features to your ride?

Sort of off topic, I ran a lowrider truck out in a small desert city in Cali a few years back when I lived back there, without a catalytic converter. I got pulled over and cited for it, they actually wouldn't let me drive away and instead had my truck towed to "a shop of my choice" and I had to have the repairs made, and also pay for a new smog check. It was a mess and was VERY EXPENSIVE ($500 for the cat itself...).

So I know all about California and their emissions leniency...there really is none.

Yeah i got stopped last night but i got lucky he was cool. He let me go but said if he heard my ex again he was going to ticket me. So i put it back on today. Mithout the muffler it seemed likemy gas milage sucked.

Exactly - because the vehicle keeps downshifting which results in higher RPMs and sometimes inefficient air-fuel ratio.

 

[shadowless127]

we get stopped for tints more then exhausts out here. I know a lot of people who run extremely loud exhausts and/or straight pipes.

 

[Got2bneo]

on the topic of gas mileage...the truck/suv(whatever you want to call it) was engineered to have the muffler not only for sound ordinances but to make the vehicle run in peak physical condition. without one you are sacrficing torque, fuel mileage, as well as ruining the codition of the motor.(pretty much restating what these fine gentlemen have already said) if you want the motor to run right in the future, an aftermarket muffler will suit you fine. even without dual exhaust my 4.0 puts out an extremely loud sound. just check out what the people at flowmaster, thrush, and maganflow have. it will save you some money in the future when your motor starts to go bad without a muffler.

 

[CALDWELL]

i agree with what was mentioned above about killing TQ...

your bad milage also im sure contributed to you romping the throttle a lil more to hear the exhaust, which all of us have done.

when i did my custom cat back i noticed a loss in low end TQ, but what you lose isnt gone, but moved into high end TQ...

and def get a muffler of some kind because i promise you will love the sound over just taking a saw-zaw to your exhaust, or just go for a cat back...
