Has anyone tried this X flow?

[Gunny]

Dynomax ... Already tried it ... it "might" work but not without some serious fabbing. It's about an inch too wide to fit comfortably. When Corey installed my Borla Challenger 2.75 system I bought one to see if it would work but the clearance was so tight that we both agreed it wasn't worth the effort. I think it's a good idea but wish the fitment weren't such an issue.

Here's an example w 4" center to center.

I looked at this design and it does have some possibilities. It is assembled from 2 stamped pieces welded together so I'm not sure how that compares with mating true 3" pipes together. It seems to me that if you could find this design with the 2 outlet pipes going straight back to either a resonator/exhaust pipes and the 2 inlet pipes splayed so that you wouldn't have to have an extra bend coming from the headers it would be a better design.

I'm trying to remember how much it necked down when I measured one but it was NOT 3" inside.

From the illustration, it looks to have a 3" inlet but that quickly necks down at the body, similar to the Mflow resonator I have. The difference being thhat the Dynomax retains 2 pipes in the resonator while the Mflow merges into one then splits back out the other side.
I think before I do anything, I'll be putting the car on jackstands today and do some measuring.

excellent idea!

Ok. Here's the dimensions I am working with:
Resonator. 18"
Xpipe. 8"
Overall length 28" incl joints
Pipe spacing 4" C to C

I got my X pipe off amazon.com. Better price than Fleebay. I had the local muffler shop remove the resonator (borla) and put this in its place. They had to add some pipe to make up the difference in length. Its now quieter and has less drone than with the resonator plus I can now clear most speed bumps.Not sure how it affected HP

You'll find more restrictions at the rear. In fact there are points on the Borla's that it necks down to 2"...Geez, talk about trying to breathe through a soda straw.
The Borla's have a sweet sound, but performance?...not so much.

related topic: Is there a good turbo muffler with a center in, dual or center outlet that fits a C4 properly? I want to try to replace my Corsa muffler with something a little more muted.

will the corsa pipes drone with a different type of muffler can? I love the no-drone, but I really need a little quieter car.

I don't think you're going to find anything quieter at anything other then WOT then the corsa's
