Rover V8 Stainless Headers

Rover V8 Stainless Headers

I’ve started to mock-up and make some Rover V8 Stainless Headers for 1/4 of the retail price! They’re made from an old vacuum cleaner, cheap Chinese collectors and laser cut header plates.

I’d been looking for cheap stainless tube bends on the auction sites and once I priced up enough to make some headers, added on some collectors, I was looking at nearly £250 worth of parts.

In the corner of the workshop was a broken Numatic vacuum cleaner with a stainless hose handle. I was about to throw it out, when I realised the stainless tube would be ideal for exhaust tubing.

The Numatic part number is 602919 – 38mm Stainless hose bend. You can buy these bends for approximately £5. The Chinese 4-1-4 Stainless collectors were £30 each. The Header plates were second hand ‘Pop Brown’ items bought at Beaulieu Auto Jumble for £10. Total bill £110.

update: buy proper tubing

Header-Merge-Collector

Initially, I was planning on using Range Rover p38 stainless collectors then fitting them back to front on the wrong sides. However, Although they fitted, there was no room left for some vital chassis bracing and the exit angles were awful.

P38 Rover V8 Stainless Headers

There are several reasons why I can’t just fit off the shelf or after-market items. The engine bay is a little tight for a Rover V8. Add in the bulky Rover P5B starter, the 4×4 front prop-shaft, chassis rails, the brakes and the steering shaft and there’s barely room left for anything; let alone a 4 branch exhaust. If I used the P38 exhausts on the correct sides they would exit directly into the foot wells.

I therefore, had to make my own. As a quick mock up, I used some tack welded, steel strips to get the collector and header plates in the right position.Rover V8 Stainless Headers

They are now all assembled and ready for proper welding.

I do have a little confession, the collectors are the wrong size. I’d ordered the correct ones (38mm) and when they turned up several weeks later, I simply put them on the shelf for a few months. They weren’t the ones I ordered. They were 10mm too big. So I had to slice and shrink them a little.

These Rover V8 Stainless headers are going to be very hard to weld properly. If my welding isn’t up to it, I have a great mock-up.

Handmade Stainless Exhaust System

Handmade Stainless ExhaustOver a year ago, I was quoted almost £1400 for a custom handmade stainless exhaust system. I'd have to trailer the car to them and leave it for a week. Since then, although not much progress has been made, I've changed my requirements and added an extra pair of back boxes. ...

IVA problems

Front suspension design has been complicated by the 4x4 running gear. It quickly became obvious that it would be impossible to use the ubiquitous Ford Mk2 Escort steering rack as it would try to pass straight through the Sierra Front diff. The push rod for the coil-over shock also tried ...

Sierra Tripod Differential

The Sierra Diff was quite hard to measure and draw up. I started with the push in shaft 7" 'Tripod' version. Most of the time drawing up this Ford Sierra Differential was taken during the measurement stages. When there are so many dimensions to be taken you almost need a 3D ...

Chassis Collection

Having debated building a 'super seven' style car for decades, when a chassis came up on ebay with a reserve of only £0.99, temptation and curiosity took hold. The auction finished with only 3 bids at £56.55. Surely this was a bargain??!? A 550mile round trip would answer that. The unfortunate answer ...
