X pipes

How many of you on here have an x-pipe? I am thinking of getting one but I don't know if there is one available for the ufc10.

its gotta be custom....

i have one.  i'm redoing my whole exhaust system this thursday and i'm using an extended X-pipe (a.k.a.- double Y-pipe) with dual mufflers running under both axles, and no cats.  all madrels too..  don't think your options are limited or non-existant because the aftermarket doesn't provide something for you.  there's always a way to get what you want.  so what's your displacement and why are you asking about the X-pipe?  power or sound?

I'm putting one on tomorrow.  I got mine from Magnaflow.  Its a universal 2 1/4"...hoping to add a few more hp to the supercharged Gs400

X-pipes work best on V configured motors or motors with an uneven firing order with two exhaust manifolds/separate exhaust sides.  It helps to even the flow and blend the exhust pulses/tones to increase flow through less vortecy (disturbance in airflow) and have a better "tone" or exhaust note.

my basic explaination as to what an X-pipe does is increase exhaust gas velocity.  since a motor fires cylinders at different times, no exhaust pulse will go through the X-pipe at the same moment, therefore the pulses will not cause turbulance.  when one pulse passes straight through one direction, it's 'wake' causes an area of negative pressure which helps to draw out the next exhaust pulse from the other cylinder bank of the X-pipe.  however, in order for this to function at peak efficiency, you'd need equal length tubular manifolds to seperate these pulses and make them uniform to pass through the X-pipe.  this is also the basis for '180 degree manifolds'.  firing order is the major factor in making the system function properly, so it takes alot of planning to fabricate a functional exhaust system to net the most power.  and by most power, i do not mean the highest peak number before redline.  i mean the highest increase in power across the powerband.  if anything, you'll see a slight drop in the peak hp number, but that will be compensated by an increase (especially in tq) in midrange power.  and if your still wondering if you need an X-pipe, it's a big NO if you have an inline motor configuration or a turbocharged application.

I have a ufc10 and I was happy when I had my system built. Now I want a little more sound and maybe a couple of ponies.

look to spend anywhere from $100-$200 on the X-pipe, then maybe another $100-$200 to install.  just make sure it's mounted as far forward as possible.  what about clearnace issues?  will you have room for it without scraping it to shit?

Burns Stainless has some nice ones...btw...I gave the short understandable version.  Most people here aren't rocket scientists...haha.  Burns costs more but they are REALLY nice:

have you used any burns products yourself?  they have the oval piping and whatnot, right?  i was considering using the oval piping for clearance issues.  alot of other members might want to consider that aswell..  i just wonder how that would affect the sound quality and power figures.  my benz rides loooow and i scrape alllll the time.  my car just doesn't look as low as it is because the bumpers are high skirted and there are no side skirts at all.  i actually raised my car back up an inch a few months ago so i can sort of clear bumps and dips until i can make a front subframe brace (skidplate) and maybe bolt on or weld on some thick slabs of stainless to the frame rails.  i'm actually only making a new exhaust because i destroyed the other one..  theres holes in it and flat spots..  and i'm only running test pipes because i smashed the shit outta my cats a couple weeks ago and the catalyst was rattling around in there.  hahaha...  my gf HATES how loud it is despite my boso/yankee style of vip tuning.  :shrug:

just to follow up, i finished my exhaust.  i used a double Y-pipe instead of an X-pipe to smooth the audible frequency of the pulse.  i can say that the before and after is dramatic.  i had duals with an X-pipe before and with my new double Y-pipe, it has smoothed the sound out almost too much.  it's now a constant tone instead of the pulseation of each cylinder firing.  i highly reccomend the double Y over a standard X-pipe!  as soon as i finish my exhaust tips, i'll post a link to a youtube vid for sure :dance:

Yes, I've used a lot of their products, from exhaust pieces and piping to piping for custom intercooler piping.  Very high quality and constancy of specs.  And yes, they carry those pipes I was referring to:
