These mufflers came off my 1996 porsche turbo. The previous owner rebuilt this it to a 3.8 with lots of upgrades. These mufflers where said to be "sport" mufflers. Other than that, I know nothing about these. They have no markings. The exit and entrance pipes are wider than normal (I think), they weigh about 12-15 pounds. I'm just guessing on the weight. The tips are welded on. It's a strange set up. They would be a perfect project set of cans.
They sounded full and deep on idle. A little louder than stock but not crazy.
$275
Pick up SF Bay area much preferred.
Thanks.
