A Couple of questions...

1.) I was wanting to get some thought on a possible custom dual exhaust on a my 97 spyder GST, of if anyone knows of a system that is pre-made. Also what are the pros and cons of a dual system.

2.) Does anyone know what the downfall would be if i removed the oxygen sensor that is by the cat.

Thanks,
ZjP

No premade, no pros at ALL.

A check engine light is all.

for #1
Pro: looks cool
Con: Twice as heavy as a single

For #2 your car will run rich if you remove it

for the duals no difference in performanc just looks. on a 4 cylinder anyway v8s/v6s get better power from duals

if youre talking about the sensor before the cat it will cause problems with idle and gas mileage the second sensor(after the cat) doesnt make much of a difference but it will throw a CEL(check engine light)
