Forget about it.  Open headers, or tuned length collectors will make more power. If muffs are required, then collector mufflers are usually prefered on the strip. I can't think of a single strip only car with a dorky H or X pipe.  SteveW

Dorky?
Gah! I say!
I have an h-pipe on my FL Hooker coated SC headers,full 2.5 inch dual 2 chamber flowmastered self bent exhaust. Granted it is not a strip car and I do agree that an h-pipe is not optimal for drag use but they do have a place.
so....
 My engine winds up smoother and quicker with the h-pipe in than it did without. It decels quicker and takes the pressure from a hard decel much better not to mention it sounds sweet at idle. I do have to say that there was nothing that was cooler than having cut-outs on the car though. They are not on this version of my tubes but it was alot of fun to uncork the pipes ahead of the mufflers and feel the wonderful power of practically open headers.

I have an h-pipe, and cut-outs that I open at the strip. Best of both worlds!

Car Craft has a low 12 second Fox Body that they dyno'd with open headers, aftermarket H-pipe, and custom built X pipe. The H pipe lost ~30 HP to open headers, but it wasn't the best H pipe out there. They used the Flowtech X-pipe and dual 3" exhuast and lost just 1-2 HP to open headers. It was a very interesting article. I think the scavenging affects of the X-pipe are very beneficial considering that mufflers were also run and very little HP was lost.

Dorky Sterling Marlin won two Daytonas using the X-pipe- his team were one of the first to use it.

Not to mention that they get in the way of the tranny when you have work down there and they also add weird stresses to the whole exhaust system compared to independent exhaust. BS

Funny you should ask  We are about to do some testing very soon with some "special" collectors that will be "joined together" in a certain manner. No mufflers will be involved of course.
Mufflers are for hot rod lawn mowers and nerd cars only!  ------------------
