Designing a Titanium Lexus LFA Valved Exhaust System – CAD Overview | 4enthusiasts

Which one do you prefer, V1 or V2?

We designed two versions of a valved exhaust system for the Lexus LFA to bring out the amazing V10 sound.

Version 1:
– Valves open: exhaust gases flow through the main two exhaust pipes
– Valves closed: exhaust gases are directed to the center muffler and exits the center exhaust tip

Version 2:
– Valve open: exhaust gases flow through the larger center exhaust pipe
– Valve closed: exhaust gases flow through the two side pipes and through the mufflers (smaller pipe diameter)
