Hi Folks,
Is this American notion that a pan of crystals in the exhaust flow will significantly reduce noxios emmissins correct ?
I have my doubts, as when living in the Mid-East, I had the two things cut ond replaced with straight through lenghts of pipe.
(This on a Pontiac Transam, 4.9l turbocharged V8 thing)
I found that with the increased efficiency of the exhaust system, I gained some power, so considerably much lighter on the gas pedal in day-to day use. Result being about a 15% reduction in total fuel useage.
Are "catties" then just a token gesture to reduce car emmisions ?
All thoughts / experiences thankfully received, as I am thinking about having the item removed from my mothers' little Chevorolet.
