I just ordered and received the catback with Hpipe and the straight pipes (w/o resonators) for a little over 300 with the SS pipes. I too wonder how loud they will be? I will find out as soon as they get installed. I have the hushpower axleback
PM senttoo many damn numbers.... i want the H pipe to the axle back but strait pipe and i wanna keep my cats... whats that part number?

What a load.
An H pipe accomplished the same thing as an X pipe, except an X pipe does it better.
I can understand going with an H to keep that american V8 sound that is lost with an X pipe, but claiming its going to make more power than any X pipe is flat out lying.
Did the information I sent you via PM help you? No response on your part after I took the time to send link etc.too many damn numbers.... i want the H pipe to the axle back but strait pipe and i wanna keep my cats... whats that part number?
Maybe because the H pipe is easier to make? Better profit margin?
I dont really know, what I do know is that 22hp from just an H pipe is absurd.
Even if they had some ridiculously optimistic dyno that was showing a 22hp gain, the X pipe would not be showing only a 6hp gain, it would be at least equal and if properly designed it should be a fair bit better.
I agree they should be about the same, but if one is going to be a little better its going to be the X pipe as it is inherently a bit better when designed right.
The point being, it doesnt make sense that theyre H pipe would make 18hp more than an X pipe. Im calling BS on that.
I think they may not be lying...that X just might not be as good a design as others. Or that's what I was thinking when I saw the video after this thread was first posted. Maybe someone who knows better can chime in, but I think an X is better off if it is not symmetrical like the have made it for the entrance and exit angle. They'e just crossing the flow and not splitting it, so it's just making an obstruction and adding bends.
I personally dont care about HP gains with exhaust. Cause dont think there is much to be gained. I like the Hpipe over the xpipe because of a sound preference. For those that have questioned me about this install, I have finally gotten the heartthrob hpipe without resonators installed. With the flowmasters I had on it sounds somewhat louder and deeper. it is my estimate maybe 10-20% louder than stock but not obnoxious loud. I love it. I will try to do a vid when I can. It reminds me of video earlier with the OR pipe but no raspiness. It has that deep muscle car sound. :rockon:
