a friend of mine has two 40 series off his mustang for 80 dollars, problem is im not a big fan of flowmaster. im listenin to some videos and they dont sound to bad, but after some searching. the 10 series doesnt sound bad at all, if yall got any videos please post

 

Hey I just put the American thunder kit on my 4.6. It comes with a flow master 40 series muffler and I'll tell you what it sounds great. Really surprised me wouldn't change a thing.

 

I did a rear cat delete and true dualed it with super 40's and have it coming strait out the back with 3.5x12 tips and love the tone its a real head turner

 

Search 0605bigred on YouTube and look for mine with the super 10, I have straight pipes now, but I had the super 10 and I liked it. Just wasn't loud enough.

 

That's exactly what I want... Can you make a video of you taking off? It would be much appreciated

 

i have no mufflers with stock cats right now, and i want somethin deep and loud. the 40's dont sound bad, i just need to figure out how to make it deep

 

It will be a day or two its real windy right now here in south texas but as soon as the wind dies down ill do it

 

Thanks man!
