I just replaced the cat with a test pipe, now I smell gas sometimes.....havent figured out when yet(partial throttle, wot, deceleration,ect). My friend was behind me on the express way and said he could smell it!! Im running a little rich but not much(1450F-EGT's). Is this normal because of the converter not "cleaning" the exhaust gases??????Anyone else ever have this smell after removing cat?????
