Do the 60's need backpressure?
I was thinking of cutting off my stock muffler and and clamping a piece of pipe in its place on my 6.0 until I can get a new exhaust. My question is would doing this be bad for the engine? Doesn't the engine require some backpressure? My girlsfriend's 05 cummins with the straight pipe from turbo back actually feels like it lost power since muffler and cat was removed. Will my truck lose some power and not be running as well if I cut off the muffler and leave the cat? Thanks
