is it possible?

[msc125]

hi all,

i\'ve got a standard mazda twin tailpipe exhaust (on the drivers side) on my fd.

i was wondering if it\'s possible to fit another twin on the other side? think it would look damn sexy with the re-amemiya diffuser.

I\'m not technical but would that mean there is to little back pressure???

Am a right or wrong (tehnical poeple) ??

Would somthing like an Apexi ECu deal with it??

I think the petrol tank is in the way.

there\'s always a way thou surely i recall seeing sum very custom & interesting scoobies with both twin rear exhausts on each side, some of which were done relatively cheaply just splitting by the back box & going over to other side which did look a bit strange if you were low enough to see this.... but otherwise a bit different....
Probably the fav one i have seen was where it split nearer the engine & came out by each side just behind the doors. dunno how popular it was with pedestrians when the flames start coming out thou :rollin lol
Could look good i guess thou & surely wouldn\'t be that much change in back pressure certainly if it was split right @ the end & consisted of twisty bits but i guess that\'d all depend on what you\'d got up to that point 5" straight thru maybe & well suffice to say i dunno jack really.
Well other than a twin zaust on one side is Cool not that i\'m biased or owt http://www.smileycentral.com/?partner=ZSzeb008\' target=\'_blank\'>http://smileys.smileycentral.com/cat/7/7_5_119.gif\' border=0>

Back pressure is not a problem, the fuel tank is the problem.

even with a new fuel tank and its still not easy.

Dont really see the point myself, unless its for a motor with exh ports on both sides of the motor like Vs and boxers, never really understood why they did it on the FC?

There is lots of stuff underneath thats in the way on the FD but as Danny says the f/tank is the biggest problem. You can always get one made up, there are patterns about for tanks that are triangular in order to make space for exits each side.

Cant see they would do power any good though, collecting and then splitting gas again?

I stand corrected

Whoever built that exhaust should be shot. A 90 degree bend that sharp will just mess up flow.

There are back boxes with dual outputs that would have suited that install much better. Spintech do a nice line that I would like to try sometime.

Hi Antony and David,
I can get you some nice stainless bends if you want to sort out the exhaust on your triple.
As Bill has said in his own inimitable way, it is not a very good system and would benefit greatly from some nice mandrel bends welded in place of the sharp angles.You will find it especially important for the supercharged engine as exhaust gas will pile up in the system at revs, exhaust flow being even more important than probably a turbo engine.
Kind regards
Carl;)

Tank is the problem, as I was having one exhaust per rotor, thought I would go all the way, would have thought an improvement as much better flow with twice as much tube, tail pipes are different now.

Was just about to say the same thing... never seen a 90 degree bend on an exhaust before...!!
