I am gonna change my catalytic converters and read about the secondary catbypass from fabspeed. I cant se anyone else who is making these. My repairshop said the 355 dont have any secondary cats. what will they do for the car? just a couple of extra Hp?
All 355's came with secondary cats just before the bypass valve. Our bypass pipes delete these cats which improve power (5-10hp) and increase sound as well as remove weight and excess heat. If your repair shop says that you don't have them, it is possible that a previous owner removed them. If your shop says that all 355s in general do not have secondary cats, you may want to check their credentials! Please let me know if you have any questions. Thanks!

The retail price for the 2.7 is $1095; 5.2 is $1495. Please PM me for an FChat discount. Thanks! Jeff
I don't have a dyno graph of just the sportcats, but you can figure on a gain of about 10hp. Please let me know if you have any questions. Thanks. Jeff
i guess the secondary catbypass will work fine if you already have sportcats from a different brand then fabspeex
i have now exchanged my broken factory cats to evoflo sportcats. What about the fabspeed secondary catbypass, will you hear any diffrence in sound and will you feel it? Will it work good if not using any other fabspeed products?
