So I am looking to start collecting parts to redo the whole exhaust system on my mustang, the headers supposedly are 1.75" runners with a 2.5" outlet vs everyone else's 15/8 with a 2.5" outlet. The brand is supposedly decent and used a lot in the 350z/g35 community as well as e46 community.

When you change the cats on 4.0 they get much much much louder, I would suggest doing everything but the cats first, see how you like it and then do hi flows later.

The headers are the hard part, putting the cats on later will be easy to do. Plus just changing from stock cast iron headers to SS you will quickly notice they are louder, some say aftermarket headers with aftermarket cats may be louder but more ricey than they'd hoped.

Definitely post up on the headers, if they work well for you, ill probably jump on a set for that price too.

I don't mind the loudness, it's no longer a daily driver and I'm planking on running a pro charger down the road so I would like to have the flow, if the sound is too much I can always throw on a set of resonators.
