I personally LOVE side pipes.....I think they look tough...but everyone will have an opinion.
one of our members here I seen has a set on there a-body but I cant remember who the heck it was.](*,)
I looked into doing them on my duster.....only problem is....I am running long tube headers .....and for side pipes to be mounted in a location far enough forward so they wouldnt look stupid....I would have had to make a comple "S" bend in my exhaust in order to connect my long tubes to the side pipes and I didnt want to put all those bend in the pipe and sacrifice the lack in HP.
my brother had a 6.6 77 trans am bandit look alike and he put side pipes on it and had to do the same thing i just mentioned....looked cool as $H!T but it lost alot of power because of it.
you will either have to run shortys headers,move the side pipes back away to make a straight connection,get rid of the side pipe idea, or go for it and hope there isnt a noticeable power loss in your system.
but I agree...they look SWEET!
