Default fabspeed etc.

Have any of you ever used the muffler bypass and cat bypass I am considering doing that rather then a full set of headers.

a moderate increase and smoother power. sounds MUCH better.

i'd imagine it would be rather loud on the street with the muffler bypass.

someone in here must have one

there's some vids on the fabspeed wesite

I have installed them, much nicer than a test pipe, good gains in mid and upper RPM

I had them on my 84. Yes, far less backpressure, to the point of noted popping, and it is louder than their video shows. Put it this way, it's too loud for std muffled track days (>95db), and it's awesome sounding enough that the C5 Vette guys at one of the unmuffled track days I did last year came up in the pits telling me how awesome my exhaust sounded.

Too loud for 7am in the subdivision by far, which is why I have an M&K on the cat bypass now.

Good luck!
