Hello, 
 
I have a 93' L-Reg Corsa GSi with the Non-Ecotec engine and am having some trouble finding a de-cat pipe that will fit. 
 
I tried to fit one that came off my mates 1.6 sport but the cat pipe on my gsi was slightly different and the de-cat pipe had no chance of fitting. 
I then got hold of a brand new Piper de-cat pipe and that wouldn't fit either.  Just like the the other one I tried to fit the bend on the de-cat pipe was to far down the pipe where the one on my GSi has the bend right at the top. 
 
Does anyone know where I can order a de-cat pipe for my GSi that will fit.

Im no expert but i assumed that all the X14/16/C16 exhausts were the same as they are all the same block. 
 
Do you still have the standard manifold on your engine?

Have you attempted to fit that? 
 
The angle is the same just the bend is in a different place...or does it just hang really low under the car?

Its to rainy to check if the manifold is an aftermarket one but I dont think it is as the car is quite quiet except for the induction kit.   
 
Mind you it does pop between 1st and 2nd gear when booting it.
