(YET) so if I did I would just put on two cats (or one for single exhaust) and then see how it sounds. If its too loud slide on a muffler when you get to the shop. Let it stick out, the smog guy won't or shouldn't get in the way of that.. emissions are his concern anyway mufflers surely aren't... |

i am talking about my v8 car and my 2.0 car.
i have thought of putting a small gas tank in the trunk with iots own fuel pump, so that i can run a gas/alcohol mixture - just for emissions inspection purposes. jim |

In most states you have to test the timing, how can your V8 car have this done??? Retarding the timing will reduce the hydrocarbons and leaning it out will reduce the CO but increase the hydrocarbons so its a balancing act. I've herd of using different fuels but a big NEW cat will clean up almost anything for a short time. I had a twin turbo rotary RX7 that was ported and ran hard. I got a cheep fuel tuner and leaned out the mixture along with adding a large cat converter. It ran just enough to get there and do the smog test. It passed and the smog tech was shocked!! Google it maybe you will get some good ideas.. Jim in your blog I noticed the 914 using the front wheel drive auto and a straight axle rear end, wow that looks interesting... Is there anymore picks and information ?? |

Wouldn't you guys just sleep better if you made what changes you needed to do to pass and left them in place? Beats having to do the dance every couple of years and you would be able to have a clear conscience...
