APR RSC 3" Downpipe with 200 cell Sport cat

Decided to take advantage of the APR summer sale and picked up a APR DP. Arrived yesterday and i decided to have it installed at Exquisite Marque in Kota Damansara



Installation was relatively straightforward, but had to fabricate a 3"->2.75" aadpter to fit the APR Centre pipe to my rear Miltek Muffler.

The APR kit came with all the adapters, clamps, even gloves for the installation, and as always, the DP is well made and solid.

First Impressions
Cruising around at 2-3k rpm, at normal KL traffic, the DP sounds totally stock. Your wife or mom could drive this car to the pasar malam and back without notcing the DP.

But when you go pass 50% throttle, the DP comes to life and theres a deliciously evil sounding PWHOOWAFAFAAAAAA ! :) Also notice a "Bliuffp" after every gear change...i love it.

Unlike my previous Cusco DP on my WRX, which was loud at all rpm levels, the APR RSC is totally silent at crusing speed, i took it it up to 120kph and it still sounded stock....

Part 2.

Have reflashed to S2 APR software, the lag is lessened and the increase in power is more noticible now. Before this, i was just toying with the idea of Brake/suspension upgrades...now..with S2..its a MUST! The car is barely able to cope with S2 power delivery, i can feel the body roll much more now, as well as the inadequecy of the stock brakes

As per my mod plan, i will be stopping at Stage 2, which i feel is the best compromise between power and reliability. Even with S2 i can already feel increased torque steer, which was not present at S1...so i can imagine that S3 would not be very drivable without significant suspension upgrades

Part 3 : have arranged a dyno shootout with my gay partner in crime, will update once done.
