I have already dropped the bomb into my 79 Bronco and don't know where to begin with exhaust, except 2 1/2 duals with flows, any particular series flow better than the rest?:confused:

Personally i like the 2 chamber 40 series mufflers, but some say they are too noisy, if your concerned about the noise, go with a 3 chamber, otherwise, go with the fore mentioned ones and feel the rumble in your chest.......mine make my house shake at idle and have recently vibrated the fascia off the garage......hehehehe:jester:

i got a 429 in my bronco.. it's got true dual exhaust and i think i'd rather have it h or y piped together.. i also have factory manifolds which i'd like to swap out.. pick whatever muffler/s you like, there's plenty of room to run almost any setup..

Seiries 50 Delta flow.
