5.9 Magnum exhaust/intake combo help

Yep, both club and regular cabs.

There was also a somewhat poorly documented "R/T appearance package" for non 5.9 Dakotas that included the R/T 17" wheels, fender flares and monochrome bumpers.

I've seen more than one of those.

I remember reading up before I bought my 2000 R/T that the engine was simply a "regular" 5.9 and even was touted as being 8.5:1 compression to run on regular gas.

I've never heard a claim of 275 HP before this thread.
