how long is the centre section on a 4 piece system..ive bought a de resonated centre and backbox that's come off a my05 sti uk and the centre measures 4ft 1.5 inches long

is that the right one or have a bought one for a 3 piece system

my car is a 53 sti type uk

 

It will be the correct one buddy as newage centre pipes are all the same lenghth

 

Just the JDM twin scroll that are shorter

 

cheers
