    True dual exhaust?

    Has anyone done this? Hehe I;m just wondering... abd if anyone did do this would it have any performance gains? I know it'd look funky but i'm just sitting here wondering.

    You realy don't need a dual exhaust unless you have a V6 or V8 (or maybe have turbo), You actually loose power with having a dual exhaust on a 4 cyl...

      Well if you were to want to have a twin turbo setup could you, Just have two manifods that go to two headers.

        So are you wanting to go twin turbo?

          No, I'm just brainstorming but is it possible another way?

            Unless your dual exhaust is made properly, you won't benefit. You'll actually do more harm than good, due to lack of back pressure, if memory serves me correctly

                  Like I said to, you will lose power, there are no gains...if done correctlly maybe.

                      Why is that relevant? The drive type means nothing. The timing technology means nothing. The fact that its not a family car means nothing.

                      It has a 2.0 liter 4 cylinder engine that utilizes dual exhaust.

                      To get any gains out of a true dual exhaust for a cb, you would have to use smaller piping to counter the lack of back pressure. Also have to spend more time than anyone wants to figuring out where the piping should go. Really not worth it unless its a major part of a big build.

                        TRUTH. Personally I wouldn't bother, plus you'd have to hack the bumper up a bit to make another cutout, unless you used an aftermarket one but that's FTL. I've seen this done before on a CB, and it sounded like complete crap imo...sorry.

                        life is good.

                          That, and you have to hack the shit out of the trunk to accommodate the other muffler.

                            I would'ent even doit, loosing power plus it'll do only minor gains due to back pressure...for a stock motor, it aint worth it.

                              Make an exhaust for each exhaust port, that's thinking at it's best!
