INSTANT G muffler. It came off my Boxster that had a 996 3.4L motor. I used it with my Supersprint headers and Sport cats. The car sounded like a Cup car with this muffler. I got a lot of compliments on the sound from fellow Boxster and Porsche owners. The piping is 2.25" instead of 1.75" on a stock Boxster (S or base).Included with muffler are 2.25" custom "U" tubes. You can install the muffler on a stock Boxster (base or S), but you will need to use a 2 reducers (2.25" down to 1.75"). You can buy these online or at a muffler shop.
The muffler had a baffle come lose at around the 15k miles. I rewelded the baffle and it is perfect now. I ran the car with the rewelded baffle for 5k miles with no issues or weird noises. The hole I needed to cut to get at the baffle can be seen in one of the pics. The welding was professional done at a high-end exhaust shop.
The muffler is normally sold for $3k including the headers and Sport cats. Google Instant G Porsche. I just want to sell the muffler. Headers and cats are gone. You can use this on a street Boxster.
