Good day all.
I recently purchased a 1997 Boxster with stock exhaust. I have been upgrading and updating her. One of the first things I researched and decided to upgrade was the stock exhaust. I next tried a China exhaust from Amazon. After watching several videos on DIY I decided to just have purchase the exhaust and have a local shop install as they would not need to remove the bummer and it should be a drop in exchange. It was
they had them swapped out in under a half hour. I new exhaust fit great, was small and lighter. I really like the dual tips instead of the oval one exhaust. I loved the deeper and louder sound, but Im sure you know what Im going to say next....yes the drone. I thought I could handle it but NO !! between 2600 and 2900 rpm's it was awful. So back to the internet. I read and saw videos of even very expensive systems still have the drone issue, so I thought what can I do the the stock (non-drone) exhaust. I have a friend that can weld and thought lets do the external bypass. After talking to him and figuring out what all that would entail we looked a some other videos of internal bypass and really liked the simplicity of the modifications so off I went to his house with the stock muffler to see how hard it would be. An hour later we had the muffler opened up and drilled the (3) 1 inch bypass holes on each side. The next day I took the muffler back to the shop and had them re-install the original muffler. Again they did it in about 30 min. When I started up off the rack I was disappointed that it just sounded like the stock muffler......then I gave her some gas to back up and ...... oh that is not stock. Off I went down the road with a big smile on my face. The new system is louder with no drone at all. At 3800 rpm it is at its loudest and has a great sound. between 4 and 5k rpms it a bit quieter and over 5k rmp it really comes alive again. I am very happy with the system. I wanted to share my experience as Im sure other have been looking for a good system. Below is a short video of the exhaust comparisons.
