Hey guys, I'm researching my options right now and here's what I got:

Option 1:
- Full Stillen Gen2 Catback System
- MR V2 Test Pipes

Option 2:
- Motordyne XYZ Pipe
- Coupe Midpipe
- HKS Muffler

Option 3:
- Motordyne XYZ Pipe
- Greddy Evo2 Axleback (Not even sure if this fits the AWD)

Option 4:
- Motordyne XYZ Pipe
- Motordyne Exhaust?? (Who knows when/if this is coming out)

Or some kind of combination of the four. I'm looking mainly at performance, I'm not too picky on sound. Loud is good, deep is good, I've rarely come across sound clips and said "eww that sounds terrible".

I know Option 4 will probably yield me the most in terms of performance but it's purely speculation at this point as I don't know when or if a product for the X will be released. What are your opinions on the first three options? What is the best combination of those products?

If I'm missing any important products don't hesitate to tell me!
