Am the only one with a bypass valve stuck OPEN? lol
Decided after owning my car for four days I needed a Capristo exhaust instead of the Tubi that came with it. The cats were failing so I ditched those for some custom straight pipes at the same time. After putting on the Capristo and driving for the first time I was devastated by how weak it sounded at higher rev's and figured the bypass valve wasn't working as that seems typical even though mechanically it was working fine when I removed it and cleaned it. I saw that the very end of the hose that runs to it was slightly frayed and nipped the end off, not really thinking it would fix the problem, but it actually did and now there is so much vacuum that the thing stays open the entire time, even after turning the car off! While it sounds great, I don't want to run it open like this all the time and would like to figure out the vacuum issue as it seems I'm the only one on the forums that has had this problem instead of it being stuck closed.
Any ideas? '98 355
