Hi ,i was wondering if anyone has taken a standard exhaust of a classic sti and welded the downpipe cat onto the middle pipe so there are 2 inline to pass the mot, just wondered if its possible as the middle pipe is easier to change

 

Have heard of some guy with a twin cat centre section but I've got mine through with just putting the centre section back on.

 

There isn't enough room to fit the downpipe cat onto the centre section pipe.

your best bet is to weld two ctre cats onto 1 centre section,trust me

 

or 1 centre cat and rev car
