AWE-Tuning Audi 4.0 TFSI Touring Edition full exhaust available for 2012 on Audi S6 and S7, +18 horsepower dynograph - $2699, pictures and sound clip
Good news Audi 4.0 TFSI V8 fans, a new exhaust option is available courtesy of AWE-Tuning. This exhaust system is available for the new Audi S6 as well as Audi S7. They state gains are 18 horsepower at the crankshaft but also dyno'd the exhaust on an all wheel drive Mustang dyno (good job AWE providing figures at the wheels) showing gains of 15 horsepower at the wheels at peak. Torque at the wheels goes from 378 to 395 pound-feet.
Those are peak HP and TQ numbers however but max gains through the curve show up to 27 crank horses at 4550 rpm and 31 pound-feet of torque at just 2500 rpm.
Pricing? $2699 for a downpipe back system with either silver or diamond black tips. Combine this exhaust with a tune to really see the numbers go up.
