I wouldn't worry bout inspection,or imissions. They can't see inside the verters, if they use a mirror or look it would appear they are stock.. You would only need to get a set of 02 simulators for the rear 02's or get a custom pcm tune, have the rear 02's turned off....

sweet thanks for the tips!

 

any recomendations on specific 02 simulators? i found alot of universal fit but none specific fit. I also read up on tha problems they had with sierra/silverado/yukon simulators. Think i could use LS1 simulators?

 

Not to up ta par on the sims, give wheatley(on the right) a call and have him do you a tune, it will be cheaper to do more then likly, you don't have to lay on your back to put it in..

YOU would want to do a custome tune after installing the high flow cats and so to take advantage of them, if not your truck would not run its best.

 

where in ri do u live in again...i used to live in sk and i never had a problem...no kittys, flows and for maybe a week at a time open cutouts...just take 'er easy round the smokeys...as far as inspection i just went to my friends shop and got a sticker...gut the cats and dont look back!

 

+1 I lost my cats as well , got the 02s turned off, i pass emission test with flying colors.

 

I live in charlestown but they all know me and my truck. all the sk and gansett cops, specially gansett. alot of em are cool but theres just some that cant stand me im gonna cut n gut the cats

 

I will be getting a custom tune either from OSP or if he gonna charge me full price again I will get a wheatley tune.
