CAT removal
Hi again,
I looked into this a few years ago but want to check again. My exhaust is ropey and blowing worse each week from several places. Ideally I'd like to replace it with something a bit better flowing, see if we can realease a few extra bhp. Simons and Jetex both seem popular 'Sports' systems. However, my car being 1991 has a CAT. B230f. Many of these sports systems are for non cat earlier cars. A few years ago when i investigated it sounded like legislstion dictated that if a car was built before X month in 92 (or something or other) then the cat could be removed. Obviously i'd then get a boss welded onto the new exhaust for the 02 sensor. Anybody know what the current regs say? Thanks |

If you get the right downpipe there's a socket for the sensor anyway.
The genuine Volvo one I fitted a few years ago had a blanking plug screwed in, as I was keeping the cat. |

Thanks guys.
I need to check with my local friendly garage really. Partsforvolvos do a Jetex and apparently Brookhouse can get a Simon's. Not sure which is best. |

Reviving this useful old thread please.

Can one buy a pipe with a boss fitted? A straight pipe with a boss, to fit instead of the cat. I seem to remember that one could do that. If I have to get a boss welded on, is it a standard boss for sensors on any car, or? And as I probably need a sensor. Where can I get a good one, obviously I will check with a dealer first. I must look to see if I need any wiring. Someone has stolen my catalytic convertor. Cut off each side of the cat. Stephen .

I've had a look and it is, promising. A little bit promising.
There is a hexagonal head about four to six inches forward of the forward CUT. Time to start applying Plus Gas I think. It looks online as if the sensor, Oxygen Sensor?, comes with a connector and a length of wiring. I think I need the three wire version for my January 1992 car? Is there any experience in the forum between Volvo Branded sensors and reputable other brands please? EDIT Feeling just a little calmer BUT. I hear there have been social media warnings of convertor thefts in the area, AND a neighbour couple actually saw it happen to my car! They did NOTHING!!! Nuf said ... Stephen .

okies
my garage, not 240 experts but they have their virtues. Say without the catalytic convertor I don't need a sensor. They might be, mistaken? So if they fit a length of pipe and discover it needs a sensor, I guess that can be fitted and while a sensor is obtained perhaps the car will be back on the road? Stephen .
