How much differance am I looking at between a o/r h pipe and a o/r prochamber besides the $100.00?

I would also like to know how good the prochamber performs.

All I know is that is sounds MUCH MUCH nastier and meaner than a regular H pipe. The thing ROARS. Performance Im sure is very minimal like most exhaust components, but I don't have much experience other than hearing the sound. Someone will chime in....

I have the pro chamber, I like it, as far as a comparison, I don't know, not many people will have had both on there car and be able to tell you the difference. The idea behind it is so you still have pulse equalization above 3000 rpm.

I dont know if its that much of a diff. My H pipe does all that.... It sounds nasty and it roars.

They have their own sound... I have one on my car. It seems deeper at idle, yet higher pitched at higher RPM. They sound a lot better out side of a car than what you think while your in the car. It's almost a cross between an x and an h. I haven't heard one with straight through mufflers, I have flowmaster 40 series and like the sound.

the prochamber is proven to give an extra 5 to 10 HP overthe o/r h...it is worth it
