  • [Corsa E 2014-2019] Exhaust System Advice Please

    Hello there, wondering if anyone can give me a bit of advice please....I own a Corsa 1.4 Turbo '15 plate. I already have a cone filter fitted but it's not really giving me the "growl" I am after. I have had a PowerFlow system in the past but just curious if there are any others over here I should be considering? I would like to fit a nice beefy system (but nothing too offensive if that makes) - can anyone point me in the right direction of which brands you've had fitted and the approximate costs I'm looking at please? Thanks in advance

    Hi Welcome to the forum

    You may have more luck on one of the forums that specialise in performance modifications. Sorry if I am stating the obvious but generally you have 3 options. Only the first 2 are road legal.

    1) A resonated system This may make claims to improve performance, but will not sound much different.

    2) A non resonated system. This may also make claims to better performance , and should sound different as it is lacking some baffles. It should still be road legal. and able to pass the mot . So the 'improvement ' in sound may not be as much as you hoped for from an outlay of perhaps £350 I know this is the main info you are seeking - which system sounds best. Sorry I cant help.

    3) a partial by- pass that is designed to be LOUD. It is not road legal. and will not pass the MOT. (or it shouldnt, Maybe you could find a deaf tester ) These systems may be cheaper -mainly because of their reduced complexity , . But these may seriously upset your neighbours,council environmental inspectors (noise pollution) ,police, mot testers and insurance companies. Even an old codger like me has a decibel meter on his phone . ( You should probably inform your insurance company of any of these modifications btw , even the cone filter. )

    Claims of improved performance are not always delivered. The original system is tuned very much for the best performance . A sports system may not give any noticeable improvement unless you also have the car remapped and stuff like that. It could even reduce performance - as can fitting a cone filter

    You also need to check whether the system will fit your rear bumper without having to cut it.

    I was young once , and can understand the grin factor of a throaty exhaust note (we had cherry bomb silencers etc back then as well ) But it may not be long before the thrill of extra noise is replaced by annoyance of a tedious drone ,especially on long journeys . These days I prefer the silent stealthy approach to extra performance. If possible dont throw away the stuff you take off. You might want to (or be required to ) revert to original

    Let us know how you get on.
