What size Borla ProXS Muffler to get?

[JustSomeName]

Does anyone out there run the Borla ProXS muffler on a v6 sr5?

I know to get the 2.5 in/2.5 out center/offset, but Borla seems to make several mufflers with those specifications in different sizes.

They have:

14" x 4" x 9.5"
or
14" x 4.25" x 7.88"
or
19" x 4" x 9.5"


My question is does anyone know what size would fit our v6 4th gens?

Also, they also have an option for a "notch", anyone know what that's for?

I think no matter which one you choose, there is gonna be some custom piping required. That said, it just comes down to how loud you want it. I would think the bigger the muffler, the quieter it will be. But if there all the same model, it doesn't really matter, at least that's what my best guess would be.

There is plenty of room under the 4Runner any of the mufflers should fit if its the correct I/O and tubing size. As stated earlier generally a longer/larger case/body makes for a quieter muffler, the ProXS series is already a very quiet performance muffler IMO. I used to run Borla XR-1's on my truck and loved it but not really any different than any other turbo/glasspack/straight through type muffler though.
