Any ideas for meatier exhausts?

Turbo style or Flowmaster might give more HP than a stock muffler, but straight through non-louvered is going to flow way better than either. Take a look at Magnaflow. Work great, and sound mean on pretty much anything, even a slant 6 :P

I find that interesting... I'll put my biased on their sound aside and talk flow. If you know what a boundary lair of air is you know that a 2" tube does not have a "working area" of 2", its less. That said that is a smooth tube, now remove that nice smooth tube for a perforated one.

Chambered or open headers...




i'll throw my car up, super 44 flow with a single 3" axle dump. Not stock obviously.
