Larini exhaust installed and you can tell it sounds much better. I need a speed detector, some more practice with the pedals, more film and an open road or track, but you get the idea. I love this car! My last three cars were highly modified mustangs with hp in the 600 range and I have to say this lotus may be slower than those, it might not sound as cool (debatable), but it's way more fun to drive! Thanks GoPro! More to come.
