Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I just made a DIY video for the TS Pro 1 Secondary Cat Bypass Pipes. Same process and directions for Fabspeed and NHP secondary cat bypass pipes. All of them claim 7-8whp and 25 lbs. of weight savings. I got a mechanic to torch off the 14 melted and rusted bolts for $50, then I drove it home and did the install. Even with the bolts cut off, everything was still stuck together so a hammer was needed to loosen everything. I did the install in the cold rain because I couldn't wait. It took me just over 1 hour. When I finally test drove the car this morning on my way to work, it was SNOWING. It snowed for 20 minutes, then rained for the rest of my commute so I did not get to test out the acceleration increase yet. But the sound was definitely noticeable. I just went out to record the exhaust sound in a parking garage to avoid the rain. Porsche Boxster 986 Test Pipes DIY - YouTube

The new sound sounds so beautiful! Were these the pipes you used? Porsche 986 Boxster 2.5L 97-99 Performance Catless Pipe Test Pipe Pipes in 50mm | eBay It says for 97-99 cars but I don't know if it is for 2000+?

Thanks, but no, Same brand, but those pipes are specifically for 2.5L. For 2000+ 2.7 and 3.2 engines, they do Not have those holes for the O2 sensor like the pipes in your link. For 97-99 Boxsters, I believe it will cause a CEL and won't pass emissions. The exhaust system design is slightly different. For 2000+ Those O2 sensor holes are not needed and do not cause CEL or emissions problems. Just keep checking up on ebay for the 2000+ 2.7, 3.2 pipes.
