    2.5i Dual Exhaust

    in Sixth Generation Legacy (2015 -2019 )

    Posted

    Yeah it will be interesting to see how this affects the low end torque. I'm hoping not too much. Haven't had the car too long. It shouldn't cause any actual damage or engine problems though right?

     

     

     

    There's a shop in my area that deals with Subarus, I'm going to ask them they're opinions. I started researching how to increase low end torque issues not just for Subarus but other people that are running into the same problem. A couple guys on this forum have mentioned replacing headers and cams. So I am looking into headers and have the cams looked at and see if the CVT can handle it. I've abandoned the intake thing because it's more helpful for fuel economy not performance. I've seen a bunch of headers for sale but I can't find the right one to fit the 6th generation legacy. So if I can find the right headers and possibly cams, that I believe will be worth the money invested. I just pray that I don't destroy the engine.

    My plan is to go with the OEM 3.6 midpipe to add the dual nameless exhaust. I wonder if I'll run into the same thing you did with losing some low end torque.

     

     

     

    I don't think this question ever got answered, but does anyone know if the 3.6 midpipe connects correctly right where the 2.5 one does?

     

     

     

    It could happen. When they put the car up on the lift. It shocked me how tight the space is where the exhaust is located. I think regardless of what size pipe you use, I'd be more concerned about how your engine will respond. Depending on how long you've had and driven your car, you're going to notice a difference in your cars response once you change the exhaust. Things become more obvious that you didn't notice before. I'm going to get the intake and let you know if I notice an improvement on the low end side.

     

    You could do a bigger single exhaust. That would be interesting to see if you can get more power without sacrificing torque.

    Just got a quote today from a local shop for the y-pipe, two magnaflow mufflers, and tips for around $500. Not a crazy amount but kind of a lot for my budget right now considering I will probably get better sound from just throwing on the single nameless for $250. Plus that keeps everything OEM. But no dual tips :(

     

    If you're not getting the whole nameless cat back, and you're concerned about money, why not just get the Subaru y-pipe and the 3.6r right side pipe and muffler?

     

    I wonder, does the extra flow with a second exit hurt the torque on the 2.5? Typically the benefit of an aftermarket exhaust is power from increased flow due to smoother bends and wider diameter, to a point, and then greater flow can hurt performance. I wonder if the 3.6r dual exhaust would improve power (greater flow after the cat) to the same degree an aftermarket single exhaust would. Anyone have any insights?

     

    Hi,

     

    It does hurt the torque on the 2.5i. I was getting too much back pressure on mine when I replaced the single to a dual exhaust, so my low end torque dropped significantly. The car really struggled to gain speed from 0-30mph off the start. On the high end side the torque is amazing, there's a huge difference. My buddy told me to install a cold air intake which should help a lot and balance it out. I just can't find one that'll fit this car. Oh I forgot to add that I had to take the car back to the shop and they had to make the pipe smaller, essentially choking the exhaust to slow down or reduce some of the back pressure. That did help, but my word Subaru is making it hard to do stuff to this car. Even wheels are a pain in the butt.

    $500 is a really good deal. Mine cost $800 for the dual exhaust for the full replacement.

    I'm assuming you put in the dual exhaust. What brand did you go with?

     

     

     

    Yup had a guy do a custom job for me. http://uploads.tapatalk-cdn.com/20160629/e43dd6430a3c9175644fff321c8853a5.jpg

     

    I've had to go to specific shops because some of the places in my area that deal with Subarus were giving me a hard time because of the model of my car. They didn't want to deal with it, so I took my business elsewhere. Through that I've ran into other car guys who've recommended the shops they go to and that's been a huge help. Hope the photo helps, I'm still not used to that type of exhaust and adjusting my driving.

    Here's a few pictures of mine I took this weekend

    Beautiful, you have given me renewed hope for this car.
