Fabspeed bypass pipes - worth it??

Did you replace the hardware with factory nuts and bolts? Copper nuts? If not, I'd suggest that. When replacing my catalytic converter pipes with bypass pipes, the muffler shop who bolted them on used normal hardware store hardware. When I pulled them off to replace the whole thing with a Fabspeed setup, the bolts had warped and loosened themselves. Before bolting up the Fabspeed, I went down to my mechanic and paid $6 for the correct nuts and bolts.

Fabspeed supplies copper nuts for the header flange bolts now. I'll re-check the tightness of all hardware after ~500 miles and will add some Loc-Tite if anything has loosened up.

Hey can anyone post weight of the bypass pipes &/or factory cat. converters?

I have my set of cats at work. Won't be back there until Monday (it's the missus' birthday tomorrow) but I will bring them home and put them on the scales.

I know where you are coming from, there is such a variance in the purported weight saving with the installation of bypass pipes, it is a good idea for someone to actually weigh them and post a real figure.

All I can say until then is that the cats are quite heavy and the weight saving is worthwhile. My estimate is about a 15lb to 20lb saving removing them, but I will have the exact figure soon.
