hks downpipe sound with stock sti exhaust.
how much will i hear? my friend is getting the hook up with a tune for me and i think a free hks down pipe.. so seriously-- how much louder will this be over stock? and the down pipe is 3 inches will i have any issues bolting up to the stock exhaust? i want this to be as quiet as possible. i DO NOT LIKE loud cars or obviously sounding exhast. i was thinkin of just gutting the first cat and selling the DP... but who knows.

I wouldn't say its going to be generally loud, but you will hear a good increase in tone. It will be a good bit deeper, and you will hear the turbo spool more.
I would say go for it, its not going to be loud enough to pull great attention or be annoying. |

you may have some leak issues at the dp to resonator pipe. hks is 3" flat flange. it will fit/bolt on, etc. but less than optial cause the pipe is designed for a donut gasket.

I'm running the exact same setup. It sounds louder than w/ the stock WRX catback, but it's much quieter than my Magnaflow catback. It sounds good from behind but you can't hear too much exhaust from inside. It's nice to have a fairly quiet car and not give up too much power.
