will these long tubes fit this x-pipe? and if so will i have to get o2 extenders?
is this a good combination and will i run into any problems at installation?

Mac's long tubes wont bolt up as SLP products are a "slip fit" connection type. You would need to have an exhuast shop change the slp to a ball and flang setup. Or the better idea would be a Mac or Bkk shorty X or H or Prochamber mid pipe.

 

If you are looking to bolt something up to Mac Long Tubes, I have a BRAND NEW Mac Prochamber for Long Tubes. I am positive they will bolt right up with no problems, and the sound is great. My friend has a 2001 GT with that setup with magnaflow mufflers and that thing sounds so mean. I'll give you a good price on it to if you want it, and i promise that its BRAND NEW, still in the box.
