just change the tip (cut off and weld in the 3.5x18 tip) and see how you like it, then give it it's break in period

 

There is restriction in your exhaust if your not getting the full sound. The stock cats are usually the biggest restrictor. They make Ford trucks the quietest trucks with our catalytic system.

If you stayed with the 2.5" dual in/single out Y pipe, theres restriction. It would be much healthier to chop the outlet end off of the Y pipe and run un-bent 3" intermediate pipe all the way to the muffler ( i'm assuming the muffler size is 3" )

If your muffler is 3" in/out, theres another bit of restriction, a full 2.5" system with the stock 2.75" tailpipe is not going to flow real well and keep a steady velocity with a 3" in/out chambered muffler.

Run 3" from the Y and a 3" tailpipe and you would be a bit happier and get that Flowmastwer 'wom wom wom' idle, and aggressive throaty acceleration.

Chambered mufflers do not contain any packing therefor they do not break in.

 

i kindda get what your tell me but everything is stock the only thing i replaced was the muffler. i also welded pieces together to get over the rear axle. the muffler is a 2.5 in/out and the pipe coming from the cats is also 2.5. so what your telling me i should do is run 3in pipe from the cats all the way out?? and how would i do that if the mufflers in/out is only 2.5 inches??

 

Well you shouldn't run a 2.5" muffler with a 3" exhaust, too late now. In the first place I would have ran everything 3" SI/SO because muffler swaps usually dont do much for these trucks. Even running no muffler wont be that loud. The stock intermediate pipe and Y pipe kill off too much volume.

 

Every flowmaster I have installed in my trucks needed to break in. They never sounded as good right out of the box, it took a while before it could get the deep tone and growl. Thats been my experience and I know alot of members here have too. Dont mean to start an argument, its just what I have found to be true.

 

I know what you're talking about, but it's not exactly a break in. That's a wrong choice of words, but I can't think of the word to say it. Darren has had Flowmaster, so he knows as well.

 

so if i do go back and re-do everything how would i get a better sound

 

I'm guessing the sound waves sound different after the baffles get dirty or the heat changes the sound the baffles eliminate, either way it takes a while to get the true flowmaster sound.

 

Wait and see.

Apparently, I learned this from Darren. The computer somehow adjusts itself, to the more free flowing exhaust, which allows a 2% increase insound or somewhat.

 

That might be true on the computer controlled trucks but I've had the same thing happen on my 68 f250, 79 f350, and 80 bronco. we need to find the term for it if it isnt "break in".

 

Man patience is a virtue. I got my flowmasters installed 2 weeks ago and they sounded like crap. Now it is getting alot deeper and louder day by day. Just give it 1000 miles and see if you like it. Spending more money should be the last thing you do.

 

I know with glasspacks I've always "broke" them in - over time it gets louder/better. With a flowmaster I'm not sure there will be a true "break in" although I'm sure the exhaust note may change some.

If you don't want to wait for it, try getting a bigger tip. Note that it won't get you a big increase in noise, but will help some. If that doesn't do it and you still are anxious to get the sound, you'll more than likely have to go with a different muffler.

In a nutshell, if you want it quite a bit louder, get a smaller/different muffler.

EDIT: That above ^^^ is great advise if you don't mind waiting...

 

i'll give it some time. And if not DARRENWS6 i will be asking you tell me exactly what you did cuz i love that sound lol

 

You'll end up loving it.

Darren has a Rear cat delete, 2.5" True dual X piped with 2 Magnaflow 11" Bodies with 4x18" Magnaflow Stainless Steel tips.

 

Well actually you guys remind me of another thing that can change the tone, if not all computer related, carbon deposits inside the muffler can fill the cracks and corners and settle to help prevent any interior leaks. I had true dualed Super 44s on my old Silverado and I actually did notice the tone of it sounded a little more mellow and deeper but very very vaugly, and the truck had a 6.0L in it which is a fume blowing engine. So that could also be another reason, but thats all that could happen. Until in the future when water vapor inside the muffler rusts out the chamber plates and they rot out and get louder.

Vaugly. I wouldn't go spending all of that money all over again though. Try what Tarajerame suggested a larger tip, then if you are still un-satisfied upgrade to hi-flow converters.

Well my specs are in the sig and in every exhaust video on my youtube with prices.
