Installed Fabspeed cat bypass pipe
Put the pipe on and just went for a spin. Less back pressure, idles at 700 RPM, about 100 rpm lower than before. Some minor rapping when you down shift and slightly more exhaust, very satisfied. It seems to have slightly more kick at lower RPM's. Have an aftermarket SS exhaust 2 out. Everything fit together well. No complaints. May just stick with this exhaust.

Any pictures? This is exactly what I am think about doing too. Any difficulty getting the old cat off? How about the O2 sensor?

Don't have my dig camera with me but everything went very smoothly. No bolts seized on either end and once the bolts were removed the cat converter came down easily. Gaskets were in excellent shape, think they might have been replaced by PO a short time ago. O2 came out very easilyas well. Not usually my mode of operation. I usually break at least one something before the job is considered a success. I will go back and check everything in a week or so to make sure all is tight. Pics would only show the shine on the pipe and the crap build-up on everything else, I have some detailing to do before I start taking pics of the underneath of my car. The car came from CA so no corrosion on any nuts or bolts as well as the PO replaced a lot of common bolts that are removed for maint with SS.
Sorry no pics but I am very pleased with the pipe and ease of installation. |
