Flowmasters are ok most people love the deep rumble but honestly if you want a deep sound that everyone will notice. Just go roush

I don't want obnoxious, and Flowmasters seemed the way to go. The Rousch is nice too.

Flowmasters are subtle and a step up from stock.

I went with with the Roush because they are docile at cruising until you get on it! You can really control the sound with them. The Flowmaster are pretty much the same tone always. I like the "growl" factor when your feeling a bit spirited.

However , I loved the Flowmasters on my 11-V6. Highly recommended for for the 3.7.

But for my CS, Roush all the way!

P.s This is how the tips look.

We have the exact same car right down to color.

Trust me when I say go with the Roush. You can control the volume of them by how heavy of foot you have.

I don't think I have a coyote, I think I only have stock 5.0. Isn't a coyote more powerful than that? Sorry for the ignorance, but from I see mine is only a stock. I have a 2012 GT/CS.

5.0 is a "Coyote". The Hi-Po model is in the Boss 302, and is the "Roadrunner".

Don't feel stupid, the people who told you about the Coyote are obviously misinformed .

It seems the general consensus believes the Borla S-Type or Roush's are the best sounding, with the GT500 w/ Resonators Deleted being the cheaper alternative.

I believe the Borla or GT500 mufflers would be the best decision if you have a modified exhaust, or plan to in the future. Roush is awesome with stock exhaust, but too raspy with a modified exhaust.

I have GT500 axlebacks with no Resonators and it gets loud under WOT. Very subtle gurgle at idle, growls at about 2000rpm, and screams after about 3500rpm. I like the idea of not having resonators in the way of the exhaust flow as well, even if there is no noticeable affect to power.

+1 for the GT500 with res delete! I have that set up and i love it. Not to loud not to quiet just perfect, ive had more compliments on the sound than i can count in the 2 months ive had them on! $319 for mufflers and $60 to have a muffler shop replace resonators with 3" pipe.

For those with GT500's and have removed their resonators, did the res delete introduce any drone?

Absolutely no drone whatsoever. I'm actually amazed at how refined it is.

I have the gt500 with res delete as well but I am also running an off road h pipe. Obviously it's louder with no cats but as soon as you drop it in 6th to cruise completely silent. But it roars at wot.
