Currently have MAC mids. If I get longtubes, will I need a different y-pipe?

What longtubes should i get that don't break the bank?

Yes you definitely will need a new y-pipe. I think there are places that sell LT's/y-pipe together, but unsure how fitment is. If it were me, I'd get the LT's and then go to a place that will fab you an off-road y-pipe.

yes, you will need a new y-pipe with the longtubes. When you purchase the headers and y-pipe, make sure the flanges are welded on already. I have seen several sets advertised for sale pretty cheap but they come without the flanges welded on. If you can weld then obviously it's not an issue but otherwise it's an additional expense that you need to be aware of.
