Has anyone tried to fit a 2014+ corsa catback on their NNBS? I thought about doing it since it's 3.5" like factory and i'd rather keep that exhaust size and not hack up my stock catback. But i'd rather not drop the coin on it if it's not even close to working.

Thoughts?

 

I had the same idea

I can't imagine that they're very different maybe move a couple of mounts and modify the y pipe connection I would V band it personally

 

Why not just buy the NNBS corsa catback? Unless of course your getting a wicked deal on the K1500 series set up.

How much do you stand to gain or lose going 3.5" from 3" ? The difference can be made up in other ways.

 

im not worried about the HP or anything to be honest. But I know the sound difference from full 3.5" exhaust vs a 3.5" exhaust necked down to a 3" exhaust system. The sound is just not as good.
