What muffler should we buy to mimic the S-Type exhaust? I do not want the entire cat-back, would prefer to dump the exhaust instead.
Earlier we were talking about the Touring which is different than the S-type.
Additionally, the S-type uses a Dual IN, Dual OUT muffler with a Y-pipe inlet and dual tailpipes. If you are trying to achieve a similar sound with a turn down, there are too many factors for you to successfully replicate the sound of a factory tuned Borla cat-back system and that's the honest answer. Dual IN, Dual OUT will produce a different sound and tailpipe length has a lot to do with how tuned or raspy the exhaust note will sound.
If you want a muffler that is most similar to the Borla S-type for the application you're trying to achieve, a Single IN, Single OUT 2.5""/2.5" Borla ProXS will be most appropriate. This will be very aggressive due to the small case size of the muffler.

For an even more aggressive sound , we have 3"/3" XR1 options. Within the XR1 line there are round mufflers, oval mufflers, small, big medium...Each will produce a different sound.
For a turn down I would recommend one of their medium sized options:

*Sound is subjective. I am using size/configuration data from the S-type to compile recommendations only.
