How can u tell the difference between milltek cat back and standard

well visually, the milltek pips are round where as OEM are oval and the milltek will have milltek written on the tips. also the milltek will normally be a lot louder and deeper sounding
 
I know. I have a milltek back box. But not sure if its just a back box, cat back or turbo back.

Cheers
 
ahhh got you
you will have to get under the car and look at where the cat is, if its just a single pipe going into and out the cat then its a tbe system, if there is a bypass pipe running next to the cat then its a cat back, very much doubt its just a back box but you will have to see where there is a reducer section
 
Thanks a lot buddy. I'll get underneath and have a spy in the morning.
