Downpipe on Stage 1 APR.

[sergemcgraw83]

Car : Golf 1.8T w/ intake, turbo inlet, and magnaflow 2.5" catback (muffler but no res) on APR Stage 1 tune.

How much gain would a downpipe gets me if I stay stage 1 (which looks like I will be stuck with since APR discontinued Stage 2)? Already ordered a Ultimate racing one with ceramic cat, resonator and 02 extension.

Also what are the other benefits? Throttle response? Sound?

Thanks guys!

You aren’t stuck yet. You have until the 7th of next month from what I was told by Arin@APR

Not to say I know how the stg 1 tune will react to the dp, but the earlier turbo spool is caused by the reduced backpressure so you will get that benefit right away.
