That will do
May be a touch loud though
ours only has a middle silencer and a very tiny cat where the back box shold be. 95db
My sytems a 2.5" all the way through (decat also) with a small backbox and mine makes decent power all day long, though its definately over 98db!
172s love bigger exhausts, unusually for an NA engine. droopy donkey dick tailpipe will help keep the noise down. If you want to be flash....get a re-packable backbox
well the cat makes a big difference to noise, and the ph1 twin cat is actually not very restrictive at all, so i'd keep that and whack on a 2.5 inch cat back
suspersprint 63.5mm race system with cat did 100db (static!) at bedford today
101db static!

Has any one ever tried altering the rear part of a ph1 cat like they do on a 182 cat? The rear part of the twin cat looks tiny and really restrictive.
^no, walk before you run kelvin
you've heard mine, Kev. That's just a back box. OMP. bwarp.
