For what its worth, here is my take on exhaust systems particularly on the MQB platform
ever since getting my MK7 R, the first mod I wanted to do was a Cat-back system.
I have looked at dozens of press release videos from different brands while getting impressed by the likes of
Bull-X ,
Levella,
Remus to name a few I never justified paying the ridiculous price tag ($2000+) for these systems especially knowing what is the cost of manufacturing these in huge quantities
The prices are somewhat justifiable for a few of the brands like Remus,SuperSprint, Akra because the amount of R&D, History and time it takes them to put out an almost perfect exhaust.
while other brands like Fi, Armytrix have the worst sounding exhaust in the market on this Platform and having been called out several times on the forums that these systems are not developed properly and in some instances will rob your power. ($ 3800 for a turbo-back
)
with that being said I decided to go a different route after seeing the Underground Exhaust system's approach in Germany, in a nutshell, they modified the OE exhaust to achieve different sound levels, so here is what I have done with mine, I call it the FSE (Fruit Salad Exhaust)
Gutted Rear section
Gutted Resonator
AWE Valve controller
CTS Downpipe (Catted)
CF Exhaust Tips

I'll take better quality once the weather gets better with different drive modes.
