The
#Supersprint exhaust for the
#ASTONMARTIN #VANTAGE 4.3 V8 / 4.7 V8 adds an incredible amount of torque throughout the entire powerband, and peak Hp, ensuring a magnificent V8 sound, at the same time.

Back in 2007 we have spent long hours in our R&D shop, dyno testing, evaluating and studying the overly quiet, standard-equipment exhaust.
We found out that the stock tubular R&L headers are built reasonably well; a good design overall, given the limitations and the space constraints of the Vantage engine bay.
While not being the ideal, perfect race headers, they leave only a small amount of performance on the table.
They definetly are not the bottleneck in the exhaust system.
Instead, we focused our efforts on improving the stock catalytic and muffler, having realized while dyno testing that they are awfully restrictive, seriuosly hampering the performance potential of the high revving, N/A V8 engine.
The decision made by our development team was about creating a new, full exhaust, from the headers back, using a set of R&L, high-flowing HJS Motorsport cats, and an oversize diameter X-pipe mid section.
Moving further downstream, we designed and built a rear muffler canister with a unique, straight-through inner scheme (with perforated cores, mandrel bent; no chambers nor baffles), which ensures the perfect flowing path to the spent exhaust gas and a controlled, droning-free sound at the same time.
Thanks to the new-found efficiency of the exhaust dynamics, the final results proved to be no less than spectacular, as the gains in torque measured between + 40 Nm and + 55 Nm, starting from 2000, all the way up to 7000.
The increase in peak Hp is equally astounding: + 32 Hp.
Not bad for a bolt-on performance addition.
We offer our rear section in three distinct versions; the Sport, The Dual-Sound (with flaps), and the Race (muffler-delete).
As with most of the Supersprint exhausts, the installation is extremely easy, with no modification required; all of these SS rear mufflers retain the Vantage std. chrome tips, integrated with the bumper.
This Supersprint exhaust fits all of the 2006-2010 Vantage 4.3L / 4.7L versions.
