The stock exhaust on the Evora is very quiet as it needs to meet strict noise requirements in many countries - especially in Europe. Naturally we want something a bit more aggressive. We had the boys at Larini send us a prototype Sport exhaust for our Evora along with a Decat pipe for the third stock cat.
The first noticeable thing was the ease of removal for the stock exhaust compared to an Elise/Exige. Once we hefted the stock exhaust out we immediately put it on our scales.
The stock exhaust was 38.45lbs. The Larini weighed in at 18.38lbs - a 20lb weight savings. The stock Cat pipe weighed 6.2lbs and the Decat pipe only 2.95lbs. Removing this last cat does not trip the MIL as it is located after the O2 sensors. This is a 23.3lb weight saving off the rear of the car! We have a Lithium Ion battery coming that will shave off a similar amount.
On start up there was only a slight increase in idle and a noticeable tone change when revved. Driving it on the street and highway showed that it is a gentleman's (or gentlewoman's) exhaust. It sounds aggressive as you rev up the engine yet it is dead quiet while cruising. The sound is very deep and muscular. We like it a lot and it suits the nature of this car.
This system came with an Oval tip but it also available with a Dual Tip. We are also planning to get one that sports a special heat resistant coating that will be white. One Evora customer, Craig, has requested black tips which we should also be able to accommodate.
