Any one run Flo Pros?

[Juge88]

Muffler guy said they are basically Magnaflows and are half the price.
I have a 383/cc503 cam with bbk headers, 2.5in spintecs, pipes and turndowns right now and they drone pretty bad. What mufflers should i run for a deep sound without drone? also should i x-pip it?

I think that the key to fixing drone is to add resonators.

not too mention.... turn downs point to the ground so the waves just bounce back and forth on the ground and under the car.... not good if you want quiet.

got a part # so we can search this muff, maybe some vids are on the net ?

Im not looking for quite but just no drone. Id like em loud as possible without the head exploding drone at 60 in OD. Would the turndowns make that worse? And i decided not to go with the Flo Pros. He just pulled them off the shelf and i read the name on the box he pulled it out of so no part numbers sorry. Any sugestions on mufflers? I know its been gone over alot but i dont know how to search on my phone.

When i got the car it had bullet race mufflers for resonators and when i cut them off it took some drone out. Not the case usually?

you just have to take the time to listen to them all until you find the one that floats your boat....

i like loud too, so i have no muffs, but i am cheap....currently building my cat-back

stock manifolds -> stock cats -> pypes X-pipe -> Spintech super pro streets -> CIA OTA pipes -> 12" chrome 45 degree slash cut tips behind rear tire.

i think it's gonna look real mean and sound tuff....
