X or H?

I love how people will say that an x-pipe gives more power over an h, yet no one has anyhting to back it up. If there is any kind of a gain from one to another, I can't imagine it would be enough to notice.
BTW, I have an off-road H pipe with Flowmasters, and it sounds really good (after I had some resonators installed!)

The following charts are rough approximations (perhaps really rough) of backpressure downstream of an H or X location. For the H, there are two traces, one for the left bank and the other for the right. The top is a straight-dual or H-configuration that does not share significant flow between the pipes, an H that shares significant flow might show values 85% - 90% as much. The bottom is an "X" with full flow sharing. Mostly, you want to just look at the occasional backpressure spikes in the H chart. Don't waste any more time trying to compare the 'Amplitude' numbers themselves as this picture was originally developed for a different purpose (sound quality comparison for a V8 with the Chevy cylinder numbering scheme).

Vasman...H pipe is definately the way to go for a nice deep muscle car sound with long tubes. The X pipe is too raspy and while it might give you 3-4 additional Hp, you will never notice it on the street. And yes, I sure felt it in the seat of the pants, after I got my Kooks LT's installed

I have Kooks LT with Borlas and X pipe no catts very loud and drone. Changed mufflers back to stock with same system.(Brent recommended)No Drone at all. Sounds awesome, alittle raspy but can hear cam alot more. I like that. Lost no HP.
