I live in Indiana where emission testing occurs often. If I gut my cats am I looking for trouble when it comes to emissions testing?

 

Removing or modifying the cats on a street driven car is illegal. Whether they will find out is another thing.

my dads ramcharger (318 TBI) has a gutted cat and it passes the dynorun here in nj, all depends on the car, it has to be there weather or not it is full is another story

my gta passed an idle emissions test last year in ny with a gutted cat, easily. dont know if it will pass the new dyno test this year. make sure it is running clean,, new plugs, clean the fuel system,, total tune up. good luck

 

My 86 IROC passed the older revving in neutral to 2500rpm or whatever test w/ a gutted cat. But the newer dyno emissions test was then implemented before my next test. It failed on the dyno test w/ the gutted cat. Two years time between the tests, so it could have been another variable, but the car passed the test w/ the addition of a new Catco cat w/ no other changes to the car.

BTW, both of my cars passed the dyno test w/ the addition of the same 3" catco hi-flow cat. $99 bux from Summit. The cat is the only emission's equipment on my 87 too btw, still passed w/ ease w/ that cat. FWIW I could notice no performance hit when adding the cat to either car.
