Aftcatalytic Converter Mail

If there s one upgrade many of us consider for our cars it's an exhaust and filter swap So when the UK importer for Remus exhausts ( offered a cat-back fully stainless system and a Pipercross replacement filter, along with a befcre-and-after rolling road run to chart any gains in power and torque, I jumped at the chance.

I've heard good things about Remus from a few mates who have systems fitted to their cars, and since they have to pass stringent TUV tests, you know they're built to a very Ngh standard. I was also encouraged by the fact that the Remus system (£506 plus an hour's fitting) not enly retains the Megane's standard catalytic converter and doesn't mess with the tailpipe finisher, but it also has a pair of silencers, so it wouldn't be stupidly noisy. The standard system is a one-piece item so you need to cut it aft of the catalyst downpipe. The two-piece Remus system then attaches with a snug, sleeved joint and clamp. It uses all the standard mounts and fits like a glove.

Running on regular 95 octane fuel, the standard Megane achieved 244. Ibhp, just a few horsepower down on Renault's factory claim of

246.7bhp (250PS). With the Remus system fitted, it develops a peak of 253.8bhp, with useful gains from 4000rpm upwards. Likewise, torque output increases by anywhere between 4 and 81b ft from 4000rpm through to the 7400rpm limiter.

On the road those gains are tangible, with a little added in-gear urgency and a sweeter, freer-breathing top-end Aurally there's little difference, save a very subtle deepening of the exhaust note. That it could pass as an OE system, but with greater performance, is perhaps the best compliment we can pay.
