95 chevy G20 exhaust question....
I have a 95 Chevy G20 van....350 TBI....
I wanna run duals on it.....can it be done? Do I need a crossover pipe for the O2 sensor ? Better to keep the cat and run 3" pipe straight back? I'd like headers, true duals....2 1/2" pipe straight back w/hi flow turbo mufflers or glass packs..... TIA Bubbaearle |

Run 'em, put a cat on both sides to keep with emissions laws, put the
O2 sensor on one side ( I've seen fords & chevys with the sensor in one pipe). I'm thinking a 95 may be OBDII equipped, if so, go cat back with 3" pipe & forget "real" duals. Good luck. |

Good luck. > Depending on where you live, it may be illegal to change the configuration of any exhaust component upstream of and including the catalyst. No headers, no replacing a single catalyst with dual catalysts, etc. Check your local laws. |

It already has 3" from the crossover back. If it has a factory system
or most aftermarket. -- Steve Williams "Leroy Stroud" > wrote in message ... > I have a 95 Chevy G20 van....350 TBI.... > > I wanna run duals on it.....can it be done? > > Do I need a crossover pipe for the O2 sensor ? > > Better to keep the cat and run 3" pipe straight back? > > I'd like headers, true duals....2 1/2" pipe straight back w/hi flow turbo > mufflers or glass packs..... > > TIA > > Bubbaearle > > |
