My truck is registered in michigan as we speak, but i am looking at going through a maryland inspection. Will i past the inspection with my five inch exhuast pipe. MBRP exhuast system has the muffler on that came with the pipe. Any ideas? I have never had to deal with inspections so i really have no clue.

I wouldn't worry about it. If they want to go as far as doing a VIN check on it (not likely) they will see that there is no CAT from factory. So your exhaust shouldn't be illegal. Is that your only concern?

California LB7s DO have the cat and EGR system on them so not all LB7s are "cat free".

cool, thanks i appreciate it. I didnt suspect that it would be a problem seeing though i still have a muffler on it. It does not blow smoke or anything when it starts. I am looking at selling it to an individual and they are worried about buying it then it not passing.

LB7s run pretty clean. Mine on a stock tune had about a 3% output. The legal limit in colorado is 33% so..........you do the math.

I have a license to inspect cars in PA. But, I sold a truck I owned to a guy in maryland. He told me that when a truck is first entered in the state you have to go buy a certain inspection. Example I had headers on the truck and he had to install manifolds

Id call a maryland inspection garage and ask them for there opinion.
