Flows sound horrible on the 4.0...to droney and raspy.

magnaflow has the deepest tone, borla is mid and fartmaster has the highest tone.

 

^ Magnaflow and Borla sound about the same...

 

from the videos i heard compared to sarahs...they dont. magnaflow is deeper and teh borla has more of a raspy but still deep.

 

Anyone have a clip or a picture of the bassani exhasut that goes all the way out the back? I would think it sounds different then the one exiting right out the side of the bed. Also, I am really liking the sound of the bassani, anyone know a good place to purchase?

 

I do like the sound of the Flowmaster the best but I agree that they drone too much. I have a SI/DO 40 series with 3 1/2" Magnaflow slash cut rolled edge stainless tips. I get a lot of compliments on the sound of it but it gets a little annoying on the interstate. I'm probably a little biased though as I have put flowmaster mufflers on 3 of my vehicles. I had 40 series on my Mustang, Big Block series on my 7.3L powerstroke and a 40 on my Ranger.

 

I had a original 40 flow put on 2 inch that the goes to 3 inch after the exhaust to a 3.5 inch tip. Its a single setup but it sound incredible compared to the 05 i had with 05 4.0 with straights. I work at a exhaust and service center and the exhaust guy tells the customers how good it sounds.

 

i have gibson single in dual out...and it sounds great. mine is OHV though, not SOHC...so that may make a difference.

 

I heard a gibson on a 3.0 and it soundsed like ***...Idk what it would be like on a 4.0..

 

dang it!! I swore I was NOT gonna start adding stuff to my new to me truck and leave it just as is...now I wannna...no I MUST put in a new exahust just cuz they sound so cool!!

I hate you all for this!!!

 

i finished installing my flow 40 3" inlet dual 2.5" outs dumped about 2 hours ago and man does it sound good. And by good i mean showing my "O Face" good! yeeeeeyaaaahhh!!

 

Thats the stupidest thing ive ever heard, everyone has theyre on opinion on what sounds good.

 

my si/do flow40 side exhaust sounds killer.....mean v6'ish, slightly v8'ish sound

 

I want to add a catback exhaust for performance and mileage but I do NOT want any added exhaust sound. Does anyone know of a factory quiet system like that?
A local muffler shop says they can add a true dual system by adding another converter and pipes all the way back for about $400, or catback with fabricated duals for $300, but they use glasspacks - and I like the quiet ride and don't want to give that part up. Help - has anyone else has tried this catback conversion and maintained the quiet noise level?

 

That seems like a good deal for true duals..

Although if you are looking for performance and mileage, i would go with a single in single out borla or magnaflow muffler with 2.25" piping.
