BOE Racing Exhaust, Quarter Stick
The first true racing exhaust for the Lotus Elise and Exige that is also suitable for daily driving.
Design
The dimensions were tested extensively with many different combinations of silencer diameter, core diameter, length, and packing material consistency to get great power, great sound, and kill the annoying drone present in so many exhausts including the factory and stage II systems.
Construction
Our BOE Exhausts are all 304 stainless construction with mandrel bent exit pipe and 100% TIG welded. Its 2.5" straight-through design reduces back pressure to support high power applications. They have been tested on cars with 320HP both on and off the race track. The BOE Exhaust is designed specifically for the Lotus Elise/Exige platform by BOE and Coast Fabrication.

Mounting
Mounted using BOE's proprietary hollow stainless steel mounting rod system. This rod mounts in the stock exhaust hangers. Through several trials, we've arrived at just the right amount of flex (compared to other rigid systems on the market), which allows the exhaust to move, eliminating the stress cracking that has plagued other exhausts. Additionally, there are provisions in the mounting system to reduce the chances of the exhaust "walking" to the passenger side of the vehicle; another problem many other systems are dealing with today. See the Additional Information tab for more.
Rebuildable
Unlike any other Lotus exhaust on the market, The Quarter Stick is rebuildable. After a couple of seasons of hard racing, you can undo the end cap and rebuild the exhaust with an inexpensive rebuild kit.
Weight
Critical to any racer, especially the Lotus owner. Theis the lightest exhaust for the Lotus
on the market. The Quarter Stick, with all the clamps, mounting rod, tip and
silencer, weighs in at just a bit over 8lbs!
Sound
Now we get to the best part! These exhausts were extensively tested for great sound as well as power production.
Quarter Stick
As in "quarter stick" of dynamite! But even our highest performance exhaust has no drone and volume is moderate at idle. Several owners have commented it is quieter than stage 2 around town (due to lack of drone). Aggressive but not raspy off-CAM. On-CAM comments from event bystanders include "sounds like a Formula 1 car," "crisp and not raspy", and our favorite, "bad ass"!!!!
This is a "high exit" exhaust, which requires removing part of the heat shielding and either trimming or removing one of the rear side panels. We recommend the Blackwatch
rear license plate bracket that replaces the rear panel. |
