Hey everyone what is one of the loudest Single in Dual Out muffler i can get that most exhaust shop have in stock. Right now i have a 18 inch glass pack single in dual out with 4 inch tips and i want it LOUDER. I need to stick with my exhaust setup SI/DO so need to know what the best SI/DO muffler would be??

 

If the glasspack isn't loud enough for you, I'd just deleat the muffler completely.

 

i cant do that for state inspection reasons. What is the loudest flowmaster for SI/DO

 

if u can run it...just do true dual 10 series flowmasters...All they will have to do is cut ur y pipe off and add these in...You will be very happy. A lot louder

 

Is the 10 series flowmaster the louder one i thought it was the flowmaster 44.
would there be any diffrence in the sound if i just did one SI/DO 10 series flowmaster here is the setup i have now

They don't make a si/do 10 series, they only make single in single out..But you glasspack in the picture is not a true single in dual out...They muffler shop just added a Y pipe after the muffler...Replace that glasspack with one 10 series muffler and you will be very pleased. Yes its much louder than the flowmaster 44 because the 44 is still a 2 chamber muffler and the 10 series is a single chamber...

 

Buddy of mine had dual magnapacks on his truck. Sounded just like his Cobra.

 

this is what flowmaster's website says about the 10 series




10 Series Delta Force® Race - Single Chamber

The 10 series race mufflers all utilize Flowmaster's patented "Delta Flow" technology and have a noticeable dB reduction over open headers. Recommended for racing applications where a race muffler is required, but without a set decibel limit to be met. Please call the Flowmaster tech-line with your specific dB requirements and applications" its saying its not intended for street use. Is this Legal to run on the truck??

 

Yes its completely legal...I ran it for 2 years...You will pass emission inspections with it for sure. All you have to have in texas is a muffler so your fine man. Trust me, I think they are like 80-90 bucks and you will be very impressed.

 

flowmasters website shows it about 110 bucks any other sites to consider getting this from that maybe a little cheaper? Does anyone know what the standard exhaust size is on a 03 f150 5.4? I want to make sure i get the right one

10 series would be a little louder man...Just think your going from a 18 inch long muffler to a 5.5 inch long muffler....Lot less restriction...

 

Well im going to have to order that tonite i was hoping to get to the exhaust shop today but no one carries them in town so i will have to wait till next week. Now the 2nd question how loud will it be on the inside of the truck? dont want the wife bitching because my exhaust is giving her a headache.

 

Check out Performance Peddler and use the discount code they give at the top "holiday4u". I just bought my Magnaflow muffler from them, it was the lowest price I found and shipped fast.
