Single shot exhaust

[turbo1962]

What muffler should I use to replace my single shot exhaust? It's went bad. Thinking about NTR or Flowmaster outlaw?

Straight through mufflers make the most power on turbo cars.
Many have said the Borla XR1 Race muffler sounds and performs the most like the original ATR Power Slot Pitbull mufflers.
I have yet to see a 2.5” single shot exhaust, but here’s the easy buttons.

Here’s one in 2.5”.

A guy put (2) Vibrant 2.5” ultra quiet resonators on his GN. He liked the sound, but was too quiet in his opinion.
If you’re thinking more sleeper, this may be for you.
