Alright. I need some help.
My current plan is this:
-APN header
-new down pipe
-thunderbolt cat 415250
-magnaflow muffler 10416
-2.5" tail pipe
-2.5" piping to make it long enough
But my question is, will all this fit together perfectly with welding? Can i use a stock down pipe or should I upgrade to a 2.5" Borla down pipe? If I do upgrade to the Borla one will it bolt directly onto my APN header?

Jeez just go to your local exhaust shop and have them make one. It'll probably cost as much if not less than a borla downpipe, and it will be made to fit your specific jeep.

So I recently got my 98 Cherokee and the muffler had 3 holes in it and was held up by a coat hanger. So I went to a local muffler shop and had a magnaflow installed. Before I had the magnaflow installed I was averaging 19mph now Im barely getting 17 on the highway. Any ideas on why? Also any ideas on how to boost the MPG abit?

Really though, its hard to say. It could be just the gas that you put in recently isn't as good. I'd wait a few more tanks before declaring a new average.
