91 4.9 exhaust suggestion

[awguthrie]

I have a 1991 Bronco with the 4,9 6 cylinder. (It has a 4" lift)

The manifolds are split front 3 cylinders, rear 3 cylinders. Trying to figure the best way to improce the exhaust.

Should I run a collector to a 3" with turbo muffler or 2-21/2" dual exhaust?

Any experienced suggestions would be appreciated.

Thanks

depends on how loud ya want it. id go with dual exhaust cause it has a nice deep rumble.

How much u wanna spend?? you will need a cat to pass emisons so.. what i would do and it is what i am gonna get on mine is a cat back system with a duel out muffler like a flowmaster 40 or 50 suv series. i'm will be going with the 50 series because i want mine quieter. u might want the 40 being a 6-cylinder.

OR you can purchace theese headers http://www.jegs.com/webapp/wcs/stores/serv...rchItemId=36787

and then have a local shop bend the pipes into true duel exhaust with two mufflers with or with out high flow cats. it's up to you but the first way is cheeper

Thanks for the input...****** always has been pricey. I don't have to pass emissions in Indiana but probably smart to consider. Just trying to get the smartest choice to let it breath a little better./ Have the K&N filter/snorkle for the input side. If I were to run duals, I should probably do a cat back with possibly "test pipe" in the cat. space.

Thanks for the input.
