APR releases Audi TT-RS RSC exhaust system, sound clip - 99 horse gains when combined with Stage II ECU Software
Here is the new APR RSC Audi TT-RS exhaust system. The system is modular and consists of several pieces. One can get just the full turbo back exhaust, the downpipe, or just the catback. The full turbo back exhaust including downpipe will obviously offer the largest power gains. APR says the exhaust plus Stage II software on 93 octane will provides gains of 99 horsepower and 113 pound-feet of torque at the crank.
The turbo back full exhaust retails for a reasonable $2,393.10. The downpipe retails for $741.60. The catback is $1,644.10.
We would have liked to see wheel horsepower numbers as well as gains with just the exhaust alone. Most people will combine the exhaust with software obviously but stating the gains with the software and the exhaust does make the numbers seem much larger.
