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 quickly found out that the stock tubular headers are built reasonably well, a good design overall, given the limitations and the narrow 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.
We focused our attention to the stock catalytic and muffler, measuring the backpressure during the multiple runs on our in-house MAHA dyno, and realized immediately that they are awfully restrictive, seriuosly hampering the performance potential of the high revving, N/A V8 engine.
The decision by our team was about creating a new, full exhaust, from the headers back, using a set of 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 "peforated-core", straight-through inner scheme, 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 exhaust dynamics' efficiency, the final results proved to be nothing 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 increaase in peak Hp is + 32; not bad for a bolt-on 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, no modification is required; all of these SS rear mufflers retain the Vantage std. chrome tips, integrated with the bumper.
This Supersprint exhaust fits the 2006-2010 Vantage 4.3 / 4.7 V8.
