They don’t do inspections where I am at. Honest, not making this up, we have one stoplight in the whole county, and it’s been there less than a year.I took the Cats off my truck. I have no problem getting an inspection. I knows ppl,,just cost a little more.
Put an HD tune up on it and it runs fast as a mother fker. Now the God damn engine can breath. I also use 15w40 diesel oil in my 496. Doesn't hurt anything as long as you don't have Cats and it protects my engine better. Has over 330,000 Mike's on it.
I loves my 2002 Avalanche 2500.
