Just for your info regarding what I have done over a few years. 2.0 Sport Tech Nav 2013.
I fitted a “Go Perform” rear box first and it was “Okay” for a couple of years. It looks nice, not the best fabrication/welding. But also may be a bit too loud for you… (all about opinions).
But we change them for a bit more noise and looks which is the whole point really.
(Probably a good track day exhaust with other mods).
I then had the Skuzzle Fast Road Package fitted this year and was well pleased with the results.
More BHP, more torque and a remap which does actually improve the fuel economy. The car drives like a dream now, better throttle response etc etc
Yes I agree with the post you have bought the wrong car if fuel economy is a concern!
Again, Admiral and very helpful.
First problem though was the Go Perform box was just far too loud and horrible to be honest. Roof up or down it drove me mad and hurt my ears in particular at motorway speeds.
Various obvious reasons why really.
That went straight away on eBay.
After a fair amount of research swapped it for the COBALT box (on special offer as we speak for for £210 from Moss yes I missed out!!).
Now that is a really nice rear box.
Comes with bolts, gasket etc. Would advise putting some exhaust paste in the join when fitting though.
Personally I have now got the car how I want it and it makes me smile every time I drive it.
My wife is happy too, so job done.
Yes an ex motor cyclist too.
Enjoy your car.
