Hey guys. Having sold my car I have my wizard big silenced decat pipe for sale and also a customised cat back. The centre pipe is standard (I did try a silenced centre pipe to no avail ) but the backbox has been reworked by the wizard to lengthen the internals and increase the volume (size) of the chamber. The boom most 147s have with after markets is totally gone. Spent all day in his lab testing and trying things out : )

Let me know if you're interested in any of the parts. Might just keep it for the day I get another Gta

Some vids of the setup were on recent threads and my YouTube

Does it fit a GT 3.2 please?

Do you have any vids of the larger back-box in action? I had Dan and Wiz modify mine about 5 times to try eliminate the boom at about 1900 revs and they managed to make it better but not eliminate it altogether. Now I have Wizard manifolds its a bit less civilized at low revs than id really like.

I have a few vids of the final internals and volume backbox, but before he put the prettier tail pipes back on .. He's made the backbox itself about 30-40% bigger in volume by adding a chamber on top, where he figured there was some space (the oem backbox is more that shape to take advantage of the space under the car)

Won't fit a GT I don't think. Maybe the big decat silencer would .. but it's made to fit equal length front pipes and then a wizard center silencer..
