Can i do this?

[Frankie]

when i do my engine rebuild, im gonna do true dual exhaust. now i have 3'' cat back on the passenger side and im cutting the cat out getting long headers and i also want to runn 3'' in the driver side. i've heard that i cant run 3'' on driver side. is this true? if so why?

The main obstacle is the transfer case for going strait back inside the frame. But you can do something similar to what Freak did with his http://www.supermotors.net/registry/4037/14853.

Good luck,

i cant check that now as im in school. but would going in front of the back tires make a difference? or is the t-case closer to the engine and trans. i havent been underneath in a while

The T-case is directly under the driver.

May not apply to the broncos..

however on my Titan, studies showed bigger is not always better. Best HP and peak HP/TQ was when ran with 2.5" exhaust tubes with aftermarket exhaust.

The back pressure is the the main issue..I'd be curious to see if anyone have done these tests on the 351/302
