Is there any companies that sell complete and REAL dual exhaust systems for the FD? all I see now-a-days are "y-pipes" ha. Let me know.

 

I think you may get more help with your search in the 2nd gen section.

 

whats the BS Flag for??

 

umm...the y-pipe takes the compressed air from your turbos and sends it to the intercooler. Not much use for dual exhausts on an FD. Your exhaust travels from your manifold through your DP and through the rest of your exhaust. Unless you wanted to fabricate some kind of "y pipe" from your catalytic converter-midpipe to 2 different catbacks then i suppose that would work but you are going to want your exhaust to be as free flowing as possible. ie: no dumb dual exhausts tips Although the 2nd gens have 2 tips but i dont know if they are both functional or not.

 

i beleive I asked about the 3rd gen, Im wondering because my cousin is going to get a 3rd gen. And if they dont make one for the car he will make one himself :P And I put the BS flag up for ***** and giggles.

There is no one that makes a purpose 3rd gen built dual exhaust. It wouldn't be feasable in the "true" sense of dual exhaust, since the stock turbos feed a common exhaust outlet to the downpipe, thus one pipe down and then maybe pull the "dual" with y pipe example. If you wanted to do true duals, I suppose one could switch out the twin stock turbos, buy a new dual, single turbo manifold, mount twin HKS GT36 turbos on said manifold, with twin HKS GT racing wastegates then you could have a true "dual exhaust" but if not, I think you're stuck with the "y pipe" route.

If you want separate pipes all the way from the engine to the back of the car you are out of luck. The car has a turbo manifold that collects the output of both turbos into a single pipe, thus dashing your hopes of true duals.

I recommend that you stay with a single pipe. Mazda made that decision for a good reason -- one big pipe is lighter and flows better than a dual system made with smaller pipes. One 3" pipe flows better and is much lighter than two 2" pipes, for instance.

I know that everyone wants to do something unique, but true duals on the FD is more foolish than clever, and clever observers will realize that. Many FC turbo owners have been converting to single exhaust after the FD made the logic of doing so well known.

A single turbo setup with a small separate wastegate dump tube plumbed all the way back would be unique and pretty cool. Do that if you long for two tubes.

Well said, Max.
