The B-RACE STEALTH performance exhaust


All the thumbnails on this page can be enlarged by clicking on them.

The B-RACE STEALTH performance exhaust is the follow on and supercedes the B-Race SnailIt was developed initially for the TS1 cylinder kit to make a touring exhaust that does not require the alteration of any bodywork to fit Series 1,2,or 3 Lambrettas. As with all B-Race exhausts they are designed for maximum torque allowing for lower revs, but utilising taller gearing. After the desired power characteristics were achieved the routing on the scooter was designed. With the Stealth, we designed an exhaust with unbelievable ground clearance (PHOTO 1). With enthusiastic riding most exhausts ground out, at best damaging the exhaust, at worst lifting the rear wheel with the resulting loss of tyre/ Tarmac contact (muscle exercising!).

Many Lambretta riders have experienced this. No degree of enthusiasm whilst riding will result in a grounded Stealth exhaust, the stand feet being the first to suffer road rash. Bear in mind (or not, your choice) suspension compression under load, gently lower your scoot over until the first contact with the ground (I suggest onto a piece of old carpet/ blanket). Engine side, odds on it’ll be the exhaust and most, the nearside too. I’ve yet to come across another expansion that doesn’t ground (Slim or Fat).I know our chosen steeds are close to the ground, but there is the available space to improve, even on
original ground clearance and increase both torque and horsepower with an
expansion chamber.
Unobtrusive looks, exceptional ground clearance, outstanding performance figures, highest quality materials (1.5mm Cr1 mild steel), individually hand-crafted to your requirements. Our design of slip joints (three in total) ensures leak free, both air in, or oil residue out. Stainless springs provide the fastening of joints, whilst the exhaust mounting points feature secure rubber mounts. This exhaust also continues the B-RACE application of a sealed mechanical muffler requiring no ìwaddingî or rivets to vibrate loose.

The Stealth was the top performer, and best fitting (a Series 1 and 2 Lambretta, both fitting to the engine and requiring no cutting of bodywork) in Scootering Magazine’s exhaust tests for both a piston-ported engine and on a TS1 engine (issues 253 and 255, July and September 2007). Following their dyno testing, it was John Balcomb’s (JB Tuning), and Andy Gillard’s (Editor, Scootering Magazine) first choice of the tested exhausts and is now fitted to a member of the Scootering team’s scooter as their choice of touring pipe.This is only part testament. Every owner of a Stealth exhaust has complimented us on build quality, fit and performance delivery, whether

specified for touring or fast riding, piston-port or reed-valve engine. This is a high-end quality British product, built to last and delivers all its promises. We endeavour to continue developing improvements if they can be found and incorporated within the design to provide you with the best available.View the pictures, read the Scootering articles and e-mail us with your enquiries (it will help both of us if you have your engine specifications to hand and know what it is you would like us to achieve regarding riding style / power delivery). We look forward to your enquiries. Thank-you, Simon and Tracy.
