As I said on the other post, I have intalled a Custom Exhaust 2 my 7.
It is a copy of the HKS. It is complete ( from the cast iron part next 2 the turbine up to the the back )

It is all made in mandel bens 3 INCH, but the muffler (last part) has 2,5 internals.....(or inlet)



WIll it be 2 bad???????

I am in process of importing a 3inc inlet muffler, to replace it.

It'll be fine, although the bigger one will flow better.
