I have a 2002 Ram Quad 4.7. I have noticed the exhaust manifolds look like P shooters. (skinny). I have heard that some engines need some back pressure to maintain torque. ?????????????:doh:Otherwise, the oem exhaust plumbing looks adequate for the 4.7 and sounds great. Would I loose low end torque if I installed shorty headers??? Has anyone done this?
