Supersprint race (front pipe + X pipe + backboxes).

Can get gains of up to 360bhp.

If purchased from Evolve Automotive you can get 15% off.

What's that, 700 bhp in total?

Not sure if still sold new, but KKS Performance catback with button controlled valve. Understood it was really pricey but it's good quality, full titanium, and possibly quite a bit lighter than stock too.

But the main reason for it is in open mode it's like having no back mufflers at all and nearing the redline gets you the naturally aspirated sound from hell

Also when lifting off throttle it's like a thunderstorm is coming with some really heavy bass. Way better than the artificial make-believe pops and bangs of most modern cars.

Just remember to only open it when it's empty around because it's really that loud.

It's a cliché but the video doesn't do it justice compared to real life (not my vid) :

For anyone wanting something that's not too loud, I highly recommend Hayward and Scott back boxes, really happy with mine, bought second hand from a forum member (thanks bradz!), mine is a daily driver, started up every morning before 7am, I live in a tiny village with the car reversed up against the house so I couldn't have anything too noisy. They're nice and quiet unless really pushing on and then still not particularly loud, almost as silent as oem on idle (apart from cold start for the first minute or 2) barely any drone, a bit bassy at around 2k rpm but that's it. Everyone told me they were really loud and not to buy them but I'm really happy, around £800 new I believe.

Maybe that's why the previous owner of my car took it off after a week...

If we could get enough people interested - I'm sure we can do a group buy deal on the BCS Powervalve silencers...
Would need 5 sets though.

I could be tempted by this, depending on the discount

I was going to wait until next year, to allow the ZedMod fund to replenish after buying the GruppeM.....but I'm sure I could be persuaded. Just don't tell the wife.
