About this deal

Availability: Problems with suppliers not delivering delayed first batch, but second lot should be available by July 2007. 01822 617624 or www.b-racetuning.co.uk So much so that it weighs less than half that of the original end can (4.9kg) and flows so freely it boosts power in the midrange by 13.5%. There’s also a removeable baffle in case you love/hate your neighbours. For a second opinion beyond the conclusions we’ve drawn, we asked John Balcombe of JB Tuning, which as a long time scooter mechanic, tuner and racer is a pretty experienced one. If you want more still from your 650 S&S have also created a pair of hi-compression pistons that boost the compression from 9.5:1 to a whopping 11:1. They say: “A clubman for a larger capacity and torquer engines, less bottom end but 1000rpm rev on over rivals.”

Availability: Any time now from Scooter Surgery (0208 748 0882 or www.scootersurgery.co.uk), just waiting for the manifolds. Items are usually sent by UPS and will require a signature. Please see below for approximate delivery times.on most six cylinder engines. The after market in the USA are way ahead and usually know what they're on about as do the aftermarket in Germany. On the expansion pipes the B-Race has the highest power and the graph suggests it would be great for touring, two-up and pretty good on a TS1. In fact it should be good on a standard 200 as well. I’m surprised that the Saigon Fresco copy has next best power, but the graph shows a fairly parallel line between the power and torque, the revs pull low rpm and it does rev on a bit. It does seem good value for money. As for the CL Race, well the engine is a bit small for this pipe, it’s too far up the rev range really. The power band is quite narrow and you can tell it was designed for something more powerful.” Our main objective is to improve the scavenging process that occurs within the combustion chamber. There are 4 strokes to an engine cycle and our concern is of the final stroke, the exhaust stroke. Here we want to increase the flow of exhaust gases by any means necessary but still allow for exhaust pulses and the velocity at which gases leave the muffler to be consistent and best suited for your specific vehicle. This hardened-up, 35,000-mile development car is fitted with two-way KW adjustable dampers, which aren't included in the kit but are worth having. They give the M520 the same solid but supple brand of body control found in the BMW M2 Competition, even if the front axle now needs a very firm hand on cambered or rutted roads. Meanwhile, fuel economy varies between 30mpg when you’re cruising off-boost to as little as 8mpg for cross-country blasts.

Type: Intriguing snail-like design, unobtrusive, performance pipe, handmade from 1.6mm mild steel in the UK. Only you can answer that. If you're hunting for the most thrilling Focus RS sensible money can buy, you'll find the M520's duality impressive.The powertrain'sdocile persona when the turbo isn't lit makes the carnoless usable than the standard Focus RS in normal driving, which is nothing short of amazing when you consider how switched on the driver needs to be when500bhp and 500lb ft is flowing. They say: Clubman for smaller capacity. Improved bottom end and mid-range with approx. 500rpm rev-on beyond others. Increasing the bore size of your exhaust is one way to achieve better performance from your vehicle. In simple terms a big bore exhaust means that you replace the standard bore exhaust system with a larger size bore. However, there is a lot more depth to this subject and it can differ from car to car. If they are unable to make delivery, a calling card will be left to inform you of the attempt. Couriers will generally make two attempts of delivery; after this time it will be your responsibility to collect the parcel from the local delivery depot near you.

The Indian-built roadsters have proved hugely popular since going on sale earlier this year, regularly topping sales charts and have only been outsold overall by the all-conquering BMW GS.

The Casa pipe makes a wider spread of power at a wider rpm suggesting it would be good for two-up touring, the flare tail having slightly more torque although the clover tail is more consistent. Out of all the standard looking pipes here though the AF is the one. It has the power and the price. The Sito Ancilotti one is okay, but it’s still no better than the AF power-wise, though it does rev on a bit, which suggests on a Stage 4200 the Sito may be the better of the two. They say: Well-established design originally pioneered by Arthur Francis and continued lobe produced today with slightly altered design for mass production. More recently we have also altered the material to a zinc plated mild steel to help against corrosion, and increased the gauge of the internal baffles to increase the robustness. Completely bypasses Triumph’s CAT, de-restricting airflow from the engine and releasing a deeper sound. Please note that in each graph, the red lines show the standard exhaust used for the base run and against which each other (green) is compared (light shades = power, dark = torque). Casa Lambretta Big Bore Clubman And so thrashing the scooter on the dyno could commence. For each exhaust, once warmed up the scooter was ‘ridden’ through all four gears and a reading also taken of a third gear roll on, the results of which have been published here.

And so to the meaty bit. It is important when looking at the graphs to appreciate all of what the dyno tells us, and not just the line you want to repeat down the pub (usually mph!). Power and torque are the keys here ladies and gents. As such, what this test has taught us if nothing else is that like ‘horses for courses’, different exhausts suit different scooters. Balls out fast riding, drinking a tank full of fuel every 30 miles, tripping speed cameras left right and centre? Then you’ll be looking for different characteristics to the couple that want reliable two-up touring on a scooter capable of dragging everything including the kitchen sink around, uphill and down vale. MIJ is at the forefront of exhaust fabrication technology, and we are always looking for ways to construct a system that will benefit a vehicle’s performance in terms of horsepower and torque. Supplied with TWO sets of baffles: ‘Straight through’ and ‘6-hole’ baffles – Easy to swap out to modify your sound!
