Yep on 2.0 Turbo engines it is (most mk3 Megane have the 1.2-1.6 engines there are very few with 2.0 spec like mine). Exact same exhaust system & engine type as the RS MK3 (RS has slightly larger intercooler & turbo boost is 0.2 bar higher). The other exhaust option for 2.0 is invisible you cannot even see it the tailpipe ends before the bumper & vents down slightly. The 2014 mk4 facelift removed the 2.0 engine option. Then in 2017 they came with yet another system which was changed again 2017-present. You can buy several different aftermarket skirts which cover & integrate the exhaust into the rear differently but most just leave it as is!
Where it counts to me is useable engine power wise it has 300 N.m (only 60 less than the RS 275!). With a simple remap its possible to gain 40 BHP & an air filter upgrade adds another 5-7 BHP. If you want to make some serious noise & attract a lot of attention then a turbo BOV on top of that will achieve this
