70mm diameter valved system for Supercharged V6
This 70mm bore system allows optimum power and torque to be achieved AND gives THE most amazing exhaust note!
The factory system weighs 14.7Kgs. Take a good look at the image of the OEM internals on the 'Questions, questions page' - you can see the restrictive nature of the silencer when the valve is closed. Lotus needed this design to help pass the EU drive-by test.
When the exhaust valve (the Engine Protection Valve) is "open", the gases are guided through the 63.5mm perforated section - waaaaay too small for a +350bhp motor.
The 2bular system weighs 12.5Kgs. I designed it for a "Road" car. With the valve closed, the exhaust gases are fed through a perforated section for "quiet " operation. It's a big silencer, the perforated section is still straight-thru with no restriction other than it being 63.5mm (same as the factory system when the exhaust valve is 'open'. You won't upset your neighbours or attract unwanted attention driving through town/suburbs.
When the 2bular exhaust valve is "open", the exhaust gases are guided through the 70mm diameter plain pipe in the silencer - there is no silencing effect at all. The sound cannot be replicated accurately on the internet/youtube. The big 70mm bore helps it to scream/wail as only an open-exhaust V6 motor can - it's very special and I'm well-pleased as I thought the factory exhaust sound was good enough.
I think the OEM trapezoidal tip is hideous. The standard 2bular layout is now the twin 100m dia tips you see in the images alongside. No other manufacturer offers these diameters of tips.
100mm dia Carbon tips are THE MOST POPULAR. 100mm Titanium can be hard to source but ask anyway.
ONLY 2BULAR SUPPLIES ITS OWN DE-CAT/LINK-PIPE TO THE DOWNPIPE FLEXY FLANGE.
THIS SYSTEM WILL NOT PASS UK TRACKDAY NOISE LIMITS!
