i have a f150 2008 5.4! want to know what flowmaster would be the best for it and what are the prices that they go for?

 

Define "best".

The responses you get to this will be very subjective and based on the posters personal taste. Do you want loud? A little growl? etc?

Youtube will have many examples if you would like to hear them.

 

Looking for something thats a little loud with some growl i would say what are the most common one people usally go for. what do they go for

 

i got the 30 series on mine. i like it. not so loud that its annoying but you still know its there. sounds nasty when you floor it though.

 

Once again, this is a very open question. Single in, dual outs? True duals, cat backs?

Based on your desires for a little loud and a bit of growl: 50 series.

 

I too am wanting to replace the factory exhaust. I want some growl but don't want it to be overbearing when driving long stretches on the highway. My 2006 has a single exhaust on the passenger side. I like the dual exhaust, but can't decide whether side or rear? Any ideas on cost? Thanx-

 

I jet got an estimate of $400 for either a Magnaflow or Flowmaster. Either a dual coming out the back or side. I explained I want it loud but not overbearing at highway speed and they suggested Magnaflow. Any thoughts? Thanks-

 

I agree with them on the Magnaflow. It will be quieter on the highway and have less drone, but still sound powerful on acceleration.

 

Thanks- that's what I wanted to hear. I just stopped by another performance muffler shop and the guy told me the exact same thing, and quoted me $50 less than the other place.

 

The Magnaflow is a fine muffler, with no drone at speed. However, I did find that it got louder with age. But, this one was on my Lightning. That could make a difference.

I found the Flowmaster (not the 50 series mentioned) did have a noticable drone at speed on my '86 Lariat.
