I tried doing my 95 300 exaust and no matter what i do it sounds exactly the same. It had a stock muffler on it i cut it off and put a straight pipe on it the second cat back sounds exactly the same and quite. Im bought a glass pack from autozone put that on same thing. Not even a little rumble. I put a flow master 40 i had on what do ya know it its still the same. At least on any of my other 300s if i changed the exaust it makes some difference. Not on this its doesnt make a difference. I dont want to cut of hollow the cat because then it will probly be too loud. and i dont want to get fined or some bs for not having one. I just dont understand.

 

Ahh the infamous exhaust issues..

Trust me, do NOT cut the pre-cat off (The one where both manifolds go into it, then exit in the 3'' pipe). It keeps it a LOT more quiet, and non-raspy/popping and crackling.

Just put the quietest muffler you can find/afford on and be done with it.

I6's sound like a Cummins/Toyota/Broken down tractor no matter what you do..

So might as well be quiet about it.

 

I know but i kinda want just a little bit of rumble. My dads 94 f150 still has factory exaust with the factory muffler on it and its louder than my truck with a straight pipe. Theres something wrong with that i think

 

If the pre cat is the one that keeps it quiet, does removing the other one do anything with the sound?

 

Yes that will make it louder also

 

Yes, makes it louder also..

But the Pre-Cat gives it an overall deeper sound. At least 2-3 times deeper than if you cut it off.

 

Does anybody what i can do to solve my problem to get it louder without cuting it off. Any of the other trucks sound would change with different mufflers but not this one

 

That's basically wondering. If you left the pre cat and eliminated the second one, would it keep the same deeper tone with more overall volume.

 

This is seriously the goofiest thing I've ever read. You straight piped it, and it was quiet. So to try and make it louder, you put on a glasspack and a muffler? Do you know what the purpose of those are? They MUFFLE the sound.

But Wesley is dead right. Do NOT try to make it loud, because they sound just horrific.

 

No i tried each one seperate. The muffler was on it when i bought the truck. And a glasspack is sopoosed to give it sound not quiet it. Not that it makes a difference anyway because every single one i tried sounds the exact same.

 

I have wasted money and chased a "Better sound" from these I6's for 5 yrs.


There are none. Only quieter or louder.

 

So you're telling me that if you scream into a glasspack, it makes it louder? A muffler is the opposite of an amplifier.
I guess I should have been more clear, not that you put on a muffler and a glasspack at the same time, but that you tried them both in an attempt to be louder than a straight pipe.

 

Straight pipe isnt loud on this truck either. Its quiet and dull sound just like as if it had a muffler.

 

That's is what the catalytic converter is doing. They serve as good mufflers. Probably because Ford also knew that the I6 sounded god awful.

 

Its kinda strange tho that my dads 94 with a 300 ans has complete factory exaust is louder than my 95 straight piped
