Just picked up my 2008 Superleggera an hour ago. I had a new LOC exhaust which replaced my Larini and here are a few observations:
1. Sound
Better, a much higher F1 pitch at high rpm, as well as a more "base" like sound at idle and low rpm. LOC winner.
2. Tourque
low end is about the same, I dont notice the difference. tie
3. Check engine light, NONE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! LOC obvi winner here.
4. weight tie
5. loudness
Although the larini was louder I dont think this is a win for Larini, with the noise a lot of "popping" which makes the car sound out of tune, kinda like a giant hunk of shit... LOC Winner
Will update you on performance as I strectch her legs manana
