Chinook RV

apparently not available any long for 1996 7.5 gas efi. Anyone??

Probably still get favorable results by looking into higher flowing cats or cat. that will be the bottleneck in your exhaust.

Thanks, I wonder if I even need cats?

Actually that's a great question. I live in Cali and its just second nature to assume so for a 96. I guess depending on where your located and what your counties emissions regulations are would dictate if that's the case for you or not. If you have Oxygen sensors in the exhaust you would need to retain those. If the chassis came with CATS with an Oxygen sensor after the cat you would need to keep the cats regardless because the pcm needs that after CAT info to calculate its fuel trim.

thanks sm350bl,

Will check into it.
