Using a maganaflow X pipe for my 3" True Dual. I need to know what size x pipe I can fit under the car. I have two to choose from,

Magnaflow Part# 12599 Muffler-Universal
6 x 12 Oval / 3 Dual Inlet / 3 Dual Outlet / 22 Body Length / 28 Overall Length

Or

Magnaflow Part# 12469 Muffler-Universal
5 x 8 Oval / 3 Dual Inlet / 3 Dual Outlet / 18 Body Length / 24 Overall Length

So which one would be betting fitting.

Here is a picture of a Magnaflow 11385 Stainless Muffler 4x9in Oval 14" Body



So does anyone have any Idea. Also I really dont know which x pipe would be better. The shorter or the longer one?

 

Bump.

Someone has to know this. Im ready to buy my xpipe

 

Well your choice is easy. Only ONE of all those have an X pipe inside. The 12599 is the only one that has the X pipe inside. But it has a 22" case length. The one in the picture has a 12" case length. You need to see what you have in terms of space. If you aren't running individual resonators after your X, then there might be alot of space.

 

well i herd people using this one magnaflow prt# 11385
