Afternoon all,

Before I gut mine has anyone got one of these available? After doing the x-pipe and deleting some cats I fancy embracing the dark side fully but would like the option of reversing if needed...

GS boxes are already valved...I dont know how "open" wouldnt be loud enough given the mods you cite...
That said, if you want to gut a pair of boxes..Id do it to a pair of 4200 boxes rather than ruin the standard Tubi made originals..
There's a pair of GS boxes for @ £1K on eBay...
or a pair of tatty 4200 boxes for a couple hundred quid..
Glad Im not your neighbour...!:D

If you are after a pair of old 4200 boxes let me know mine are causing much clutter and need to be gone

Cheers for the replies - fortunately I don't have close neighbours! My thinking was to still have the original valves so I could be quiet when needed but open up the other side so could be a hooligan as required - are the 4200 ones valved at all as per GS or just one 'system'?

Have you got a GS or a 4200? You really don't want to gut GS boxes. Apart from anything else, in open mode they are pretty much straight through, I believe. Same like GTS

nope , Gs boxes are still very silenced in open mode .

Indeed the car is not excessively loud at the moment I would say - very much improved with the other mods but not ott - would say my Lotus Elise is probably louder, mind you that has an aftermarket exhaust and hurricane induction system...!

Would prefer to still have an ungutted set to put back on if needed hence seeing if anyone had any knocking about but am still still considering doing mine - at nearly 100k miles done it is now probably worthless anyway!

Like it! No option to make it quieter though for stealth mode which I like with the standard boxes....decisions, decisions!
