I am looking to put on a true dual exhaust setup on my mustang and I see that pwrhse has the prochambers that go with the true dual exhaust on their web site and if I am not mistaken they are the same ones that go with the 4.6L on the GT. If that is the case, will a MAC or similar X-pipe or H-pipe hook up to our little stallion? I am going to put on GT mufflers with the GT stock dual pipes that go on just in front of the mufflers and need some advise on what type of X or H pipe to use. I am currently looking at an X-pipe by MAC that has removable straight pipes up front where you can replace the cats with these pipes or use your stock cats. Does anybody have any experience or knowledge if this type of setup will work? Will I have to have the pipes cut, rebend and/or welded to get them to fit? Any help would be greatly appreciated!
