I realize this is an older thread. I'm not especially fond of symmetry for the sake of it. I'd rather have real metal wheels than fake plastic covers. When it comes to the 2014 Forester XT I'm curious about replacing the dual exhaust with a single exhaust....if there is agreement the duals do nothing for the performance of the car?
Any recommendations? I don't want louder nor drone but I'd rather have a single pipe instead of the posturing of a dual exhaust. Thank you.
Without all your other words... just say, "I preferred a single exhaust. And I put one on." If you're really happy with how it turned out, share pictures of your work and any tips you might have learned with others. That's always appreciated.
But there is no posturing going on. Assuming you've read the entire thread, you're obviously not the first to question why, when the Past use of dual exhausts meant probably more power and a V8 under the hood, does this little four banger have duals. Looked at in today's world, however, and you find good reasons why there are dual exhaust outlets, and mostly dual mufflers, on modern cars.
Noise regulation is the major reason. Two mufflers are better than one, all things equal, for minimizing power loss. But our noise regulations give us little choice... either a more restrictive exhaust, a much larger muffler, or dual mufflers to quiet the horses. To replicate the exhaust flow AND sound level of your FXT with a single exhaust you would need a much
larger muffler. But where's it going to go? They take up too much space as it is... but that sound-reducing bulk is shifted into two equal symmetrical locations that minimize the impact on storage and interior room.
The manufacturers would love to reduce costs and use one muffler. They can't.
The world thinks that's a good thing, even those who couldn't care less about power or sound levels. Why? Because symmetry is fundamental to life as we know it. Without belaboring the obvious, an otherwise perfectly symmetrical vehicle with dual, symmetrical exhausts, simply looks Right.
A single exhaust on a Forester XT would actually be more "posturing" than the duals. Make it as effective as duals and it will really make a statement... because it will be an obvious alteration... like an eye patch or prosthetic on a living creature.
But if you like it and want it go for it. Just don't try to convince everyone else. Your why's are yours, no explanation needed.
