Hi guys. 

 

I know there is a very good reason why companies charge what they do for exhausts as it is no easy feet. 

 

But I'm curious. 

 

The vrs has a twin box doesn't it? 

 

What would happen if you went straight from downpipe to a single backbox? 

 

Which would be best grade of steel to use? 

 

Benefits of thinner/thicker sidewall? 

 

Thanks guys 

My old vrs had no centre section, just a sports cat and rear box.

 

Wasn't / isn't overly Tbh.
