The entire factory exhaust weighs about 38.6lbs with as someone else showed about 12.4lbs of that being the midpipe. So the stock axleback weighs around 26lbs. The Nameless axleback is around 16lbs, so it shaves around 10lbs of weight off of the stock exhaust. I think it weighs a little less if you go with their smaller mufflers.
When I spoke with Nameless they said their re-designed midpipe with a resonator ended up weighing more than the stock midpipe and made negligible power so they felt it wasn't worth selling, it would just add weight and cost people more money.
Perrin's complete catback weighs more than the stock one, unless you get the option with no resonator. The catback without a resonator weighs 26lbs total, so about 12.4lbs less than stock. But then you have to deal with a louder and probably raspier exhaust.
As for dyno numbers, this is what Perrin got out of their true catback, with the resonated exhaust. When they dyno'd the car with just a straight pipe after the stock midpipe, it made around 3WHP. This is how they showed replacing the stock midpipe definitely had an effect on performance, at least in their testing:
I can't seem to find any numbers from Nameless with just their axleback, I think it made around 3WHP.
I'm going to probably buy the Perrin without the resonator and then have the car dyno tested without it and then with it just for my own piece of mind.
