The exhaust and pipe finally arrived from the UK and Sector 111 will be installing it on Tuesday of next week. We are assuming that it has the resonator and we will replace it with the straight pipe and then replace the main exhaust with the Larini sport exhaust. I will post a review afterwards. This will be the first one done by Sector 111 on an S version. Fingers crossed there are no surprises. I am also hopeful since all of the changes are downstream from the O2 sensors that there will be no CEL's to deal with. Time will tell. The mechanic is experienced with Lotus cars as he was the former mechanic at Symbolic in La Jolla, CA when they had the dealership here in San Diego. Bring on the ruckus!
