Default K04s, downpipes, and milltek exhaust

Anyone care to comment on how this set up sounds compared to just the milltek. Or put another way, is it possible to go with K04s and keep the sound close to stock without losing the performance gains?

Default yup, I've heard his car

That's partly why I was asking. I thought he was running test pipes at the time though... and Borla is louder than milltek, isnt it?

Default I have KO4's and Milltek turbo-back WITH cats.......

Not too loud at all. Infact I noticed no difference in going from KO3's to KO4's in overall loudness. Slightly more turbo whine under hard acceleration but that's it. Very close to stock in my opinion.

Default Is that with downpipes or stock with precats?

I'm assuming downpipes without precats, but just want to be clear.
