Catless downpipes but keep orignal secondary cats
Hey guys just wondering if anyone one is running catless downpipes but still have there secondary cats in place? would I be able to pass an emissions test with a setup like this ? also would the secondaries be sufficient to eliminate any smell? Ive looked this up already online cant find any sufficient information on this topic ...
