Aston Martin V8 Vantage Equal Length Performance Exhaust Headers 4.3L 4.7L

  
I bought them a couple months ago although I have decided to sell my car. There has also been the EGR tube added to this set, if your removed the EGR from your car then the flange can be covered.

The finest V8V manifolds on the market, these are aftermarket replacements for the extremely restrictive OE manifolds on the Aston Martin V8 Vantage. Designed to complement our 200 Cell Sports Cats, these manifolds are equal length (down to the millimetre) and features a beautifully crafted, bespoke merged collector. The gases from the four flows on each manifold are merged in perfect equality, which prevents power being robbed (like the OE manifolds are guilty of).

These manifolds are TIG welded by hand by a specialised fabricator and are made of 100% stainless steel. The manifolds, in conjunction with our 200 Cell Sports Cats, boast (extremely conservative) dyno-tested gains of 49BHP with an accompanying 13-15% of additional torque. With an accompanying ECU remap, the 4.3 Model can easily outrun a standard 4.7 Model. Initial primary diameter is 40mm, transitioned into 70mm secondary, and flared to 76mm for the catalyst flange. Each primary pipe is exactly 400mm long.
