Re: X- Piping Exhaust After Mufflers?
You can still do it, and it might balance/mellow the sound a bit, but you won't get the flow benefits of a crossover. The idea is to balance the flow between sides before the restrictive parts of the exhaust (mufflers, cats, etc.).
What type of clearance issues are you facing? |

Im Running The Exhaust Through The Frame and With a 6-8 Drop I Dont Wanna Run The Exhaust Much Lower.

Re: X- Piping Exhaust After Mufflers?
Any photos of your exhaust setup? I too am running mine through the frame currently, but have room for a crossover. The mufflers are actually outside the frame rails, and the crossover pipe is inside the frame rails.

Re: X- Piping Exhaust After Mufflers?
By through the frame do you mean through the trailing arm crossmember or through the actual frame to run outside the frame? I'll be honest, of all the dual exhaust I have run on all the trucks I've owned I have never run a crossover

Re: X- Piping Exhaust After Mufflers?
This is a cut and paste from a article on X Piping your exhaust:
"An American V8 with a cross-plane crank doesn't fire alternate banks consistently. The firing order means that you sometimes get successive exhaust pulses into the same manifold. In a dual exhaust, this means inconsistent pressure pulses in the two sides. Look up "beat frequency". When you have two frequencies that are almost -- but not quite -- the same, the difference causes a low frequency pulsation (beat frequency) that gives the American muscle car its distinctive low frequency rumble. The same thing happens in twin engine aircraft when you don't "synchronize" your props -- the rpm difference between the two props makes for a low frequency throb you can feel as an intermittent vibration.

Re: X- Piping Exhaust After Mufflers?
I managed to chop up and stuff a 3" x- pipe and some dynaflow mufflers under my cab. If I had the resources, the lengths worked out where I could have punched holes in the xmember and run the exit pipes through.
