A completely new development, with interference at the front in 45 mm Stainless steel.
Perhaps a little ‘over the top’, but we wanted to offer a perfect manifold system that leaves nothing to be desired.
Performance and torque were the main focus, but durability, weight, fit, etc. were also important.

The Details:

The interference is plugged, not welded, to prevent stress cracks. The connection is ‘double-sleeved’ so that no exhaust gases can escape from the connection. Due to the taper at the end of the manifold, this manifold set is compatible with all interference pipes from 850-T3 or the Lafranconi LM-1/2 exhaust pipes.
Both sides are equipped with a plugged M 18x1.5 thread for mounting one or two lambda sensors.
The bending angle of this system also allows installation on California models with the long side stand. With this design, there is also significantly more clearance to the generator avoiding heat problems.
The flanges supplied are CNC milled from solid (7075) aluminium and are therefore very sturdy, unlike some accessories. On the cylinder head side, the manifold is not only flanged, but also has a solid ring welded on for maximum durability, tightness and stability in the cylinder head.
The supplied flanges, together with the stainless steel clamping pieces, securely hold the manifold in the head.There are four types of flanges to choose from, all sturdy, only a matter of taste.

We offer this set in 3 finish versions.

1. Stainless Steel natural, etched. Suitable when appearance is not the primary focus, or when polishing or painting is required.
Production marks may still be visible.


2. Stainless Steel etched and matt glass bead blasted.


3. Stainless Steel etched and brushed. The finest finish of all.

All versions are etched inside and out to prevent corrosion. Not just treated on the outside to make them look decent. They are etched in a special bath to also reach the inside of the tubes. Stainless steel is also prone to corrosion if heated up like on the welded parts and also in normal operation. The etching process also reduces discolouration when exposed to heat.

The set consists of:

1 Downpipe set, surface finish of your choice
2 flanges of your choice
4 Stainless clamp pieces
2 Downpipe gaskets
4 Cap nuts
4 Schnorr washers
2 Lambda plugs

 

HMB-TIP

The best choice! Rustproof, complete with flanges, precisely fitting with an inner diameter of 42.6 mm for the main pipes and the interference pipe. This ensures a noticeable increase in performance and torque in all speed ranges.
The reason: the back pressure in the exhaust system is reduced. This is due to the optimized bending angle and the large inner diameter of the pipes. In addition, each exhaust stroke can use both tailpipes, as part of the exhaust gases can flow via the interference, thus also involving the opposite tailpipe.
In short: the engine breathes easier.
The tone of the exhaust system becomes slightly duller, less ‘rattly’, which is particularly beneficial for the open Lafranconis.
