Difference in H-Pipes...

[UofMfooTbaLL24]

I currently have stock headers and Flowmaster 40 series mufflers on my 98 GT. I don't plan on getting aftermarket headers, so i was wondering... does an offroad Mac Prochamber really sound that much better than just a Mac offroad H-pipe. I can get a Mac H-pipe 140 shipped and I think the prochamber is 219 + shipping. So my question is, does a prochamber really sound that much better to justify the cost? Also... how do I use my stock 02 sensors on the H-pipe that i decide to get?

Thanks

I talked to a guy who had both h-pipe and Prochamber with Spintechs. He said the Prochamber has a deeper sound than the H. I have his old Mac H now with the stock muffs and like it.

The Mac H and Prochamber both have the o2 bungs for installation of the sensors. Just screw them in.
