X or h pipe, your thoughts guys

[Ofnaman1]

Like stated earlier, engine masters did a whole episode on this subject for comparison of power. Honestly, there is no noticeable power difference between H, X, or none, on a stock or mild built engine.

With that being said, I have ran and installed x pipes, h pipes and duals with no crossovers. The sound difference out of the tailpipes is all about the same (assuming the two tailpipes exit the rear of the vehicle or same side). The sound inside the cab is much different. X and H pipes both knock out almost all cab droning noise in my experience with aftermarket mufflers that generally produce droning noise (ie, flowmaster 40's, which I almost always run). I love the look of x pipes, but they are not always easy to install if you do not have the room. On my ls9 c10 we have dual 2.5" exhaust with flowmaster 40's. When we had the exhaust built, the exhaust shop forgot to install the h pipe. Driving it with no h pipe was pretty terrible in the cab. When we took it back, they installed a 2" h pipe and it made all the difference. Well worth it in my opinion. If your hoping for more power, save your money......
