We ship the Accessport directly to you from our distributor, so it will get to you before all of our parts do. The only exception to this is if you are having the bundle delivered outside the USA we have to ship everything together.

All downpipes in this bundle come with an extra o2 sensor bung and plug for running an optional Wideband A/F Ratio guage

Please note:

  • This bundle REQUIRES a tune for proper vehicle operation.
  • Turbobacks are often sent in multiple shipments. DO NOT schedule your install or dyno-tune until you have confirmed receipt of ALL parts. Orders cannot be canceled or returned because an install was scheduled prior to receiving your parts.



  • Muffler Delete: The loudest option. Removes the mufflers entirely. This is a 10 on a scale where stock = 0
  • 4" Mufflers: Similar to the deletes, but with the edge taken off. This is a 7 on a scale where stock = 0
  • 5" Mufflers: Our most quiet option. Perfect for those looking for a subtle upgrade. This is a 5 on a scale where stock = 0


  • 3" Double Wall: These are T304 stainless, staggered double wall polished tips that fit perfectly into the cutout in the rear valence of the vehicle. 10 Degree Angle Cut with staggered arrangement (inboard tips stick out 1/2" further than outboard tips). 3″ diameter per tip, very close to an OEM look
  • 3.5" Single Wall: Staggered ingle Wall Quad Tips in 3.5" diameter w/ 20 degree angle cut with a 1/2" staggered arrangement.
  • 3.5" Neochrome Single Wall: Same as above but with blue flame/burnt tips fit perfectly into the cutout in the rear valence of the vehicle. 3.5" tip with a 10 Degree Angle Cut with staggered arrangement (inboard tips stick out 1/2″ further than outboard tips).
  • 3.5" Double Wall: Staggered Double Wall 3.5" diameter quad tips, 1/2" staggered arrangement, straight cut, brushed finish.
  • 4" Single Wall: Staggered single wall 4" diameter quad tips, 1/2" staggered arrangement, 10 degree slash cut.
  • 4" Double Wall: Staggered double wall 4" diameter quad tips, 1/2" staggered arrangement, 10 degree slash cut.

  1. The sound.......

    Posted by on

    Sick exhaust system. Takes some time to get but WORTH the wait. Add this an intake some new injectors and fuel pump and go from 265whp to 320whp on your STI.

  2. Great build quality and amazing sound!

    Build Quality:

    Build Quality was fantastic! You could tell right off the bat that this was handmade by professionals who took their time.


    Installation was a pain in the butt, but at no fault to Nameless. I am rather handy when it comes to working on my car, but this install still took the better part of a day to complete with a helper. My recommendation would be to have it professionally installed if a downpipe is being installed as well. The Catback portion should be fairly easy to install.


    OHHHH EMMM GEEE!!! I LOVE the sound of the muffler delete option as it is very throaty and aggressive. The first 1,000 miles were loud and had a bit of a tin can sound to it but it mellowed out once it had a layer of exhaust gunk in it. It is incredibly loud when accelerating, but does quiet down when cruising at around 3k RPM and when idling at a stop light. Highly recommend the muffler delete for those that want a loud sporty aggressive sound!


    I went with the 4" staggered tips and they look amazing! They fill in the valence well and line up perfectly if you take the time to install it correctly. Definitely gives the entire rear end of the car a sportier look that it should have had from the factory.



  3. LOUD!!!

    Posted by on

    After install the system was above and beyond what I was expecting. Wish there were some instructions for installation included with exhaust. There are a lot of parts and some of the connects seemed a little unusual. The Y pipe came very close to the rear control arms but have not heard any rattling or knocking. Definitely recommend the stiffer hangers to keep things in place since it's so close to other parts of the car. Otherwise I am in love with the sound and performance. After a pro tune it has been a great purchase. It is LOUD!!

  4. Best exhaust on the market today!

    Posted by on

    I can't believe the quality of this exhaust. The welds are awesome, the fitment on my car was perfect and the sound is pure Subaru. My car is now honestly the best sounding Subaru that I have ever heard. It may take forever to get your exhaust but this is definitely worth the wait. You will not be disappointed. I have the 4" mufflers and they are still pretty loud but not too loud where you can't hear anything. I couldn't imagine the muffler deletes. I am so happy that my Subaru finally sounds like I want it to.
