hi, i've searched around and came up with nothing. I was just wondering if it is possible to make a dual exhaust, not like the dual apexi one, but like the 350z's? would the piping fit at all, or does the rear end get in the way? i jus think it would be unique n pretty dope to have a real dual exhaust. thanks for ne replies.

it would not be a real dual exaust unless you have 2 manifolds which a 4cyl doesnt

or you could make 2 manifolds, each for each pair of firing cylinders and bring it to the back...although O2 sensor positioning would have to be in just one of the runners.

Well, with enough money you can do anything, but it''ld still be superficial - aka rice.

relocate ur gas tank to an all aluminum one in ur trunk, or fabricate a nice one to go where ur stock one went, and somehow get it on there, and then u can make urself some room for the second pipe.,, but ud have to make urself 2 seperate 2-pipe manifolds that dont get in the way of eachother, and then fabricate some 3 inch piping to go to the back of the car that also wont touch eacother.. thats 6 inches of space you will need. so im not sure if that will be good..

what you could do is make some brackets, and then squeeze some high-temp silicone onto the sides of the exhausts, then hold them together with metal screw-clamps.. and then when it sets, they wont rattle against eacother and can run the length of the car.

i would only do this for a turbo application..in which case, your dumppipe will have to seperate into a Y pipe. and u wont need to make that double exit manifold.

yeah i was thinking seperating with a y pipe, easily done at a muffler shop. A fuel cell located inside the car came to mind as well. And yes this is for a turbo application, so im not worried about back pressure all too much. then i'd have to cut another hole in my rear bumper. ne one know how much an aftermarket fuel cell would be w/o me having to search b/c im lazy? hehe. i got it kinda planned out i guess, but was jus looking for some suggestions. thanks, someone wanna help make a pimp ride?

If you make it functional then cool, I like, but please oh please don't put a fake setup with one real and one fake, that's super rice.
