I have prepared this article on exhaust systems as they relate to the Rover SD1 3500cc V8 engine. Before making any decision on the type of exhaust to fit, try to understand the science in simple terms, the general principles of exhausts and why they are designed the way we have to buy them. In addition what changes can be made and how will they affect the performance of the engine. Finally, in practical terms, what modifications might we make when seeking improvements. This document attempts to provide the insight needed to understand all the above issues.

Saw/Grind cut-outs to tune system for minimum resonance and optimum gas flow. Works great! Hi-quality image from UnoHoo! . AlternativelyA commercial exhaust baffle that can be inserted into any pipe of the system for noise reduction. Not so cheap and probably more difficult to tune than a cheap DIY version.  What about the SmellStraight tailpipe S/S exhausts cause toxic smells to enter the cabin via the tailgate vents because the aerodynamics traps toxic fumes in the high pressure vortices behind the car . To fix, fit swan neck pipe. Cast Iron Manifold vs Tubular HeadersIn the Parallel Universe of the Rover SD1 Club Forum a member asked - "It's said the standard EFI cast manifolds are a pretty good design. Would be interested to know if the tubular ones are any better on a standard engine?" That question has been reviewed in depth - here: Rover SD1 Tech'l Articles:.......................................................................................................Site Contents: |
