X Pipe or H Pipe???

motorjock205 · 06-22-2004, 12:29 PM

I have a basically stock 1996 Mustang GT, I've added K&N Filter, removed the air silencer from the housing, and have Flowmaster mufflers, 5 speed. I can't for the life of me figure out why this vehicle needs 6 catalytic converters on it!!! I want to only keep two for emissions purposes where in live near Dallas/Fort Worth. What the heck is the difference in an X Pipe and an H Pipe, and can I use cats I already have or do they come with the pipes??? Don't want any check engine light coming on either after the switch (pet peave)!!! Someone shed some light on this for me if you can...

The X-pipe is for extracting the next pulse from the engine. Kind'a like a collector. You get firing order 15426378, works for 1-5, and 6-3... but not that well on the rest.
Also they need to flow extremely freely, in order to work (i.e. not street mufflers). IMOHO, an H-pipe balances the odd firing orders just as well.

The sound difference alone kept me clear from the x.. As far as the engine light goes-mil eliminators---I believe i got mine for my 97 for around 50 bux!
