Making That TwinTurbo V8 Rumble // Estoril Blue S7 AWE Exhaust Install

Eight seems to be the preferred amount of cylinders in high-end sports cars these days, and every effort is made by owners to make their V8 known. Not that we’re complaining.

Audi is known for putting big turbocharged V8’s in their higher end cars, such as the sought-after S7, S8, and RS7. Particularly, the S7 features a 4.0L twin turbo V8 that pushes out 420hp/406lb-ft torque paired with the famous Quattro all-wheel drive. There’s only one problem: the growl of that glorious engine is quite subdued. Don’t worry, there’s a fix for that.

Naturally, AWE Tuning offers an exhaust system for the S7 that is perfect for enhancing the sultry growl of the turbo V8. Luckily, a customer who just so happens to own a 2013 Estoril Blue Audi S7 agreed that the rumble need be heard, and so here we are.

We installed an AWE Tuning Touring exhaust into his S7, consisting of non-resonated downpipes and polished quad 102mm tips. The exhaust offers peak gains of 18hp and max gains of 27hp, not to mention it “is remarkably civil while idling/part throttle cruising, but unleashed at full throttle produces what some have called a ‘war-cry wail.'” He was quite pleased with the results!
