VelocityAP 200-cell High-flow Cats (V8 Vantage)


More power and more sound – what’s not to like? These 200-cell catalysts are less restrictive for your exhaust system, allowing your engine to breathe more easily. You’ll get approximately 15 bhp and 15 ft/lbs, plus a more aggressive exhaust note.

Installation hardware included, and you can check out my DIY Guide if you’re installing these yourself.

An easy modification to do to your 4.3L  or early 4.7L V8 Vantage, high-flow cats and a tune are what I recommend for people looking to get more power out of their car without breaking the bank. I highly recommend getting a tune to get the most performance from the high-flow cats.

This product is designed for off-road use only.

NOTE: These are for the 2006-2010.5 (pre-MY10.5) V8 Vantage. They will not fit a 2010.5 or newer (post-MY10.5) V8 Vantage. MY2010 was a transition year so you’ll need to see which exhaust system you have to ensure you order the correct parts.
