Porsche 996/997 ( Gen 1 ) Silencer Bypass Pipe
- Product Review (submitted on April 1, 2017):
I had this done to my 997.1 C4S and having had a H&S systems on cars in the past (They came with them, I hadn't been to H&S myself), I contacted them, booked it in and dropped it off, left car with them while I walked down to a cafe and had a full english. About an hour later it was done and in their words "It sounds like a Supercar now"... And it does. I looked at the backboxes and the welds were excellent and the sound? email me and I will send you a video of it.
I went for the middle option (1.25, 1.75 or 2 inch bypass pipe It may have been 1.0, 1.5 or 2 but it was the middle option) and it sounds amazing, especially when heel and toeing.
