can any shed any light on wether a cobra backbox would fit straight onto my car. 53 blob sti. non resonated centre section.

I wanted to order a new back box but ive been told that they don't fit the standard system and I would have to buy a cat back.. is this right?

 

Bolted a Cobra back box straight on to my standard centre pipe, unless you have a non standard fitment centre pipe there shouldn't be a problem.

 

I bought a cobra non resonated full system a few years back and found it too loud so swapped the centre part to a resonated one.
From memory I'm sure it was only about 100 quid.
So not the end of the world of the back box doesn't fit

 

cheers guys

 

yes should be straight fit..........
