well...... i have found (ithink) the reason for my major power loss!!!! the catalytic converters are gone!! i was driving the other night and caught the smell of rotten eggs! bummer!! oh well...... since i did the turbo swap on my car, it has had no *****!! now i know why!! ok, my question is this........ i just purchased the bonez racing cat and downpipe combo from rx7.com, are those emissions legal???????? and will my car be louder when i put the downpipe on????

 

The car should pass emissions. The volume of your exhaust may not differ from what you have that bad now....but the tone of it should a bit.
