hi looking to upgrade to stage 2 on a sensable budget does anyone run their downpipe onto oem exhaust if whats the outcome with sound and performance
many thanks
 
I am running a 3" cat-less downpipe into the stock catback on APR Stage 2. The power increase was noticeable, even before flashing the APR map. The sound is still pretty quiet at idle and cruising, but when you give it some throttle it's louder than stock. The exhaust sound is also more noticeable on cold starts until the engine warms up. Also the sound of the turbo spooling is much more prominent (which I like!)
 
Hi,

Im running a milltek downpipe with 200cell cat with a reducer to a standard cat back.
Im on stg2+ with no issues.
 
What would you see more gains from own a stock map.. Cat back or down pipe with sports cat?
