Classic backbox
 

Looking for something a bit different from my current Magnex 3.5'' back box. Louder, but hopefully still able to get on track - though may keep the Magnex for that. [ Rest of system is H&S downpipe & Magnex resonated centre ] Had thought of H&S Scoobysport or Afterburner vortex...

Must fit standard diameter centre.

Back box...
 

Try Scoobytec.......they have a great bb for £199. inc. postage and VAT.

It really is a good piece of kit.

Im selling my hayward and scott for £180 +p&p but that only has a 3.5" rolled in tip so probs not much different from your magnex :s

I have a TSL group N for £150 - 4" exit, will pass trackday dB tests will bolt straight on to your Centre section.

I have an H&S backbox for sale would suit the rest of your system.

Just how loud is that thing ?? Looks like a monster! Where are you based?

I'm based in north london but could bring it to Japfest if your there. Its fairly loud but its the rumble that get my neighbours. Very low note.

I will be at Japfest - in the SIDC area - mind you so are about 450 others ! PM me your mobile number and we can meet up.
How much are you looking for - was trying to keep the costs below £150 - but see you were after a bit more than that on your for sale thread. [ What did it cost new ? ]

Cheers
