Yall think that it would effect the way my 2.9L runs if I remove the two cats and keep the flowmaster 2 chamber.
I'm sure it would sound good but im worried about lack of back pressure.
Oh yah, its no where near street legal anyways.

Red neck, just the same. Though it's hard to keep it red through the winter! I spend a fortune on tanning beds. :redneck: :canada:
