The XYZ pipe will fit with stock exhaust... You have the option to get the HFC, resonator, or straight pipe module... Then the rest of the exhaust hooks up to that...

 

HFC bolts to the XYZ, but after that it's V-clamps, unless MD now has a "module" that allows stock exhaust from there using bolts+gaskets.

 

My 03' Z is totally stock at the moment but i have a JWT pop charger on the way and im saving up to get the TDX2 and ART pipes in the summer. What headers are you guys running? is there a big notice in sound/gains with headers? im also ordering a 5/16 plenum spacer but ill be installing all of this stuff when it warms up in a month or so.

 

I have an 07, i'm not sure on the DE but everything i've read on this forum shows that intakes/headers are a complete waste of money (minus the PPE longtubes) do your research before you buy anything

 

^like the above post, I have heard that there is almost no gains from stock HR; headers aren't worth the $$ and effort for little if any gains, that's what I understand anyway.
