What's are the Pro's and Con's of either pipe crossover?

Does it matter what crossover I use?

Proposed setup: Delete 4 Cats and replace with http://www.summitracing.com/parts/MPE-94106/ then run a 2.5 crossover of your choosing (X or H), into 2 http://www.summitracing.com/parts/WLK-24215/, then have http://www.summitracing.com/parts/MPE-35117/ tips.

Any suggestions/ideas?

Thanks.

X-pipe is better for overall performance, while the H-pipe sounds better.

 

Yeah the x helps balance out the system and the h does it as well, but not quite as well. It adds that chop to the system vs the x pipe. TO be honest, I would go with the x, the go with what you want more ( more of a stang type sound or more balance for performance) It's not a big difference.

 

the x-pipe is what I would do, and will do on future projects.

 

H pipe
cant wait to hear this setup

 

X Pipe, FTW.

 

the h pipe will help in the lower to mid range rpms sound a bit "choppier" while the X pipe helps in mid to higher rpms and sound a bit "raspier"

 

x-is for low to midrange torque gain/retention-

 

openclasspro#1 says "x-is for low to midrange torque gain/retention"

which one is it guys!?

 

I say just flip a coin lol its your personal opinion on this one OP... I wanna hear some sound clips of this setup! Its gonna sound mean!

 

not that it matters or anything but here's a dyno chart comparing the 2 and my point is made...

there ya go. exactly why i said H pipe in the beginning. thanks pal

 

Correct. X pipe will help better in the low to mid range.


What vehicle was that tested with, a Mustang? Well there is a major difference in the under body of an F150, and a Mustang, its the fuel tank. Because of the F150's fuel tank location, you cannot run the X pipe right after the tranny and run the mid pipes straight back and out, the left bank needs guided over to the passener side which takes about 3.5' of extra pipe just to re-route the Y pipe area, and additional 4' - 5' for a left side tailpipe, and the passenger bank will be about 7' - 8' shorter, very unbalanced, so in this case the important thing is to balance it correctly from the start since the tailpipes dont matter for performance, balancing with an X pipe will cross flow and equal out the proper scavenging to perform correctly.

 

Damn it man, they had me convinced that I had the better setup than what I initially thought until you posted that write up.

 

Well its good you still have a cross over anyways, your high end rpm will like it more.
