Following a couple of requests, I've been out and taken some photos. As you can see, I didn't clean anything first.
The end-piece is a cut down boy-racer thingy from Trago. The finisher was cut and filed from a bit of (spit!) chequer plate that I had lying around.
The silencer is one of these, and sits nicely between the wheel arch and the chassis.
JETEX - HANDY ROUND 250MM (125) 2.5 - J-HANDY-25
it is mounted rigidly on 3 home-made brackets, so as to prevent it rattling in the hole in the body panel. (The flexi-pipe takes account of any movement).
The inner end of the silencer connects to one of these
JETEX - JETEX 45 DEG. BEND 2.5 - J-45-25
which connects to one of these
JETEX - FLEXIBLE PIPE 1/2M 2.5 INCH - J-FLEX-25
then one of these (the landy pipe is 2 1/4" diameter)
JETEX - STEPPED SLEEVE 50.8/57/63.5 OD - J-SS-25
It joins the stock downpipe just in front of where the first silencer box was originally.
I made a cock-up joining mine and had to do a bodge, that's why there's so many clamps there - there should be only 2!
The system is a bit louder than standard, but not outrageous.
the lack of paint on the sill, below the exhaust exit, is nowt to do with the exhaust. That was over enthusiasm with a pressure washer.
