Muffler qeuestion

hey guys, dont flame me but ive been thinking of altering my 240 for a batman style tail pipe(out the center instead of the right and side of the bumper)

how much do you think im gettin into?
i already know i will have to alter my fuel tank, but by getting a tank fabricated on a slant the fuel pump is over enough i think… and maybe is i split the tank into 2 tanks connecting by pipes on the top and bottom and having the tip through the center would allow for minimial loss of feul holding capasity…

what do you think??

Start sketching/photoshoping w.e

it should look good…
post a picture of the rear of your car…and i’ll be your bitch
