My mate has recently got an astra mk4 deisel, and we've put a scorpion backbox.  
 
I just want to know is there any way of masking the engine noise through the exhaust system? I spoke to A1 today and they insisted that I will never be able to make a diesel exhaust system load. 
 
I was thinking WTF! why do they have the center silencer there for then? 
 
How much of a difference will replacing the center silencer part with a straight thru mild steel pipe make? 
 
We just want to mask the engine noise with a louder exhaust system. 
 
Any diesel owners care to help? 
 
 
Cheers

no just had back box. most diesels usually have no centre section so i thought what the point of havin a new centre section. i thought that bcuz the backbox was less resrictive it'd be a bit more noisier but its quieter and can hear the turb whistling

I would imagine you can get the exhaust loud if needbe!! straight pipe should do it lol 
Think of tractors, they are diesels and loud
