So right now I I'm running a 3'' x pipe and flowtech afterburner mufflers dumped at the axle. I'm wanting to switch to something else and I have come to the conclusion of dynatech splitflows and single chamber flows. Is there any weight difference? How is the drone and resonance between the two? Is there any flow difference? BTW I have already had dynatechs on this car but I was running them straight off the headers so I'm wondering how much the x pipe would change the sound.

The biggest question I have is will I notice much or any performance difference from the flowtechs to either of these other mufflers?

 

I don't have a direct comparison but I do run the splitflows. The x pipe will quiet it down a bit and should improve low end torque as well. The spliflows are a straight thru design so no real restricltion at all.

 

I've used both single chamber mufflers and Dynatech Splitflows. Ran the same ET's with both and the Dynatechs were MUCH quieter.

 

I have single chamber flowmasters on my ta. They are loud and have alittle weight to them. The sound is nice though. Its not annoying like some.
