Flowmaster 50 series

 

Basically it’s a consistent, steady, unchanging tone low to mid rpm band. Especially up-hill with around 1800 – 2000 rpm that tends to annoy everyone in the car. Installed in the same location as stock with the stock rubber brackets by a Ford dealer.

 

I know a V6 is totally different than your V8, but I put a Flopro V-Force SI/SO on my V6 and kept the stock pipes - no drone at ALL. My sister and nephew both have Flowmasters with stock pipes on their V6 Rangers and they do nothing BUT drone. Whatever you use, rubber mounted hangers and full tailpipes exiting behind the wheels or straight out back will minimize drone.

 

I have the exact same problem at the 1800-2000 rpm range with the Banks Monster exhaust. It goes beyond annoying in mine, at precisely 1900 rpm on a slight grade I bet I can run you out of the cab. I have been researching for the past couple of weeks trying to identify and hopefully resolve the problem. At first I thought it was the clamps and mounts too, I replaced all the standard clamps with accuseal band clamps and torqued to spec from the front to rear. I also tried adding more support in certain locations by using large hose clamps from the piping to the frame to see if that would take out vibration to no avail. I really hate this because at every other rpm the Banks sounds awesome, but I stay in that mid range too much for it not to bother me.
I think my specific problem is because I have a regular cab truck. Most of the major brands like Borla , Corsa, ect. don't even offer a system for the regular cab, and for those that do all the R&D and optimal tuning goes into the CC/EC and the regular cab is just a retrofit.

I can vouch for Banks that they do have good customer service though and they are trying to help me solve the problem. The standard muffler for the F-150 with thier system is 16", and they sent me a 24" muffler to swap it out with. That brings up another interesting detail, the F-150 is the only truck that uses the 16" while thier system for Toyota, Nissan, Chevy, and Dodge use the 24". Anyway I guess I'll know whether this will work or not once I get the time to modify my pipes to fit in the new can.

 

Thanks everyone for all your responses. Lots of choices makes it tough to choose.

Does Magnaflow provide the length in their item description? or is this a buy the generic muffler of a lenght you want vs the cat back kit?

Thanks again!!

 

Which Cherry Bomb muffler do you have? I see they have a Vortex, Turbo, Pro, Elite all available with SISO. What length is the body?

 

I have Cherrybomb Pro muffler 2.5 SI/SO 14 inch body

 

I have a 2006 Ford F-150 EXT CAB 4x4 and went from a MAGNAFLOW to a CORSA...There is no comparison I love the sound at cruise and it sounds great when under acceleration...DRONE IS THE BOOM YOUR GET WHEN DRIVING FROM AN EXHAUST

 

How do you like ur corsa? What one do you have; how is the drone on the highway?

 

Acutally after going back and looking at the paperwork from the exhaust shop, I also have the IMCO (now Cherrybomb) Pro. They told me it was the "HotRod" muffler but the paperwork says Pro and the model numbers match up to the Pro series. Mine is #7458 3" SI/SO, with 16.5" body, 22.5" overall.

 

I just put on a MAC exhaust system(TK5505) and have absoulutely no drone whatso ever and the best part is it sounds like my old 5.0 and it was cheap..........

 

Did you install it yourself?
How was the fit and finish?
Which length muffler did the catback system use, 18" or 26"?
Is the muffler a straight through design like a Magnaflow or a turbo style?
Can you hear the exhaust inside the cab at all through any RPM range?

Thanks,
Mark

 

I have a SISO Magnaflow on my 1999 and there is drone when cruising. I don't mind it too much, but I will not be putting a Magnaflow on the 2007 I ordered as I want something quiter on the inside as I am on the highway a lot.

 

yes on a buddys lift ( no joke 12 minutes)
Fit and finish is outstanding( not stainless except tips)
18" -3" inlet with dual 2 1/2 outlet behind tire looks like harley
straight thru design
it sounds GOOD from idle all the way through the gears but at 65-75 there is no drone and barely audible but kick it down and she's there

 

I have the sport version and love it...
